RockStar 4.0

RockStar 4.0 The 4th Generation of the most decorated freestyle/playboat design ever made takes freestyle kayaking to new heights… out of the water.

Here is what you the Rock Star 4.0 Delivers:

Lightweight: Pick the boat up and you’ll feel what an unwavering commitment to making the world’s lightest plastic freestyle kayaks is like. On the water your moves will be snappy, easy, and you’ll be given every advantage that a lightweight boat can give.

Comfort: Slip into the boat and you’ll immediately feel how we improved the comfort, foot-room, knee pockets, and the view from the cockpit.

Durable: Our perfected composite/plastic track combo for the hull support prevents oil canning and deformation of the hull. Your boat will be ready for the biggest waves, the best rock spins, or running down the river to the next playspot. The shape of the bow and stern are designed to take hits and hold strong. While shallow looping holes are abusive to any boat, you’ll be glad you are in this one when you hit hard.

Dry: We have been trying to create the driest boat in the world with each generation. Zero Holes are drilled into this new Rock Star on the outside where it can leak. Compare that to 11 holes for the competitions boats (or more), and add in one of the driest cockpit rim designs possible and you can paddle without water in your boat. If you want to know how dry your gear is, paddle our Rock Star 4.0.

The most aerial boat we have ever made is designed to help everyone get out of the water for the first time, or get more air than ever before for the experienced paddler. The two main venues we designed this boat to excel are on waves and in holes.

  • 9  - Drier Ride

    We have been trying to create the driest boat in the world with each generation. Zero Holes are drilled into this new Rock Star on the outside where it can leak. Compare that to 11 holes for the competitions boats (or more), and add in one of the driest cockpit rim designs possible and you can paddle without water in your boat.
  • 10  - Big Air

    Big Air “Huge” Bonuses are not only going to be easier, but we’ll set the new standard for just how high out of the water the judges will expect a boat to go! If you are just learning to loop, this boat will launch you higher than any other design, giving you the time and air to complete your first loops. For all of the moves where air is possible, the bow and stern of this boat are carefully shaped to combine a slicey, easy-to-move-around shape with an explosive thrust upwards and a clean release from the water.
  • 11  - Retentiveness

    Sticking moves is not only fun, but critical in competition. The Rock Star 4.0 has the side view shape, the volume, and fast rotation speed to give you more margin for error than ever before. Less boat in green water, more in the foam, more upstream launching, and slightly narrower and more forgiving hull for landing makes sure you spend your time in the hole, not in the eddy.
  • 12  - Speed

    1” longer than the Rock Star 3.0 with an adjusted rocker profile that works across more wave shapes and speeds than the previous model to allow you to drop into just about any wave with more speed and potential energy for take-offs.

    When will they be available in Canada??

    1. July 22, 2018 at 2:14 pm

      Check with your local dealer in Canada, they are shipping to US dealers now and it’s all depending on who got their order in first. We have several here on the Ottawa but I’m not sure out West.

    Hello! Is there paddler weight ranges you could share for each of the sizes? What would best for 140lb female? Thx!

    1. July 22, 2018 at 2:13 pm

      If the weight ranges aren’t up yet, I would likely wait for the Small at 140 as the Medium is bigger and I’m sure the Small will be slightly bigger than the 16 model as well. Check back to see when the specs get posted – boat is due in August! Clay

    At 6’, 185-190lbs I’ve felt like i was between sizes in the previous 3 rockstars. I can’t quite squeeze into the medium and the large feels big even with the seat raised. You think I can comfortably paddle the new medium?

    1. July 22, 2018 at 2:12 pm

      Hey Andre –
      YES. While you will still be on the upper end for the Medium it will both float you higher and give you more leg room than either the 14 or 16 versions. They are also narrower, so if you want a big floaty boat you won’t have to paddle such a wide hull in the Lg when it comes out in August. I’m 175 and very happy with the new Medium, have seen if float someone at 200 lbs. Clay

    Which size for a 6’, 185-190lb paddler? Currently in a large 2016 but looks I might be a medium in the new boat? Thanks!

    1. July 22, 2018 at 2:04 pm

      Hey Paul –

      I think you’re on the bubble and might want to try the Medium and then try the Lg when it comes out in August to compare. I’m a fan of the Medium at 175 – it’s a great floaty fit compared to the 16 version – and have seen people 200 lbs play the medium WELL. How it compares… we’ll see in August! Clay

        November 17, 2018 at 4:43 am

        Is paddler weight with gear or no gear in general?. You at 175 is it with gear or no gear?

        1. November 24, 2018 at 9:04 am

          Paddler weight on our specs was formulated by EJ so it = your weight in nothing but a Speedo swimsuit. If you don’t have one, it’s about 2 lbs less than wearing your shoes, jeans and a T-shirt. Since everyone wears about the same gear, and no one wants to get it wet and weight it, we factor that stuff in.

          Good Question – I think all kayak companies decided to go this route years ago because it just makes sense. Clay

    Great to see a new freestyle boat. I’ve got a 2016 Rockstar so will be interesting to compare. Working in a kayak shop I am sure I will be quizzed about it very soon! A quick question for you. As there is 6/7 extra gallons in the Medium I presume that the paddler weight ranges for both the Medium and Large Rockstar have changed somewhat? Do you have figures yet? Cheers.

    1. July 22, 2018 at 2:02 pm

      Check to see the specs on the website – yes the 4.0 is a bigger boat and will fit a bigger paddler. I’m 175lbs and felt the 16 was on the smaller size for me. In the 4.0 I’m feeling the size is fantastic. I also had my feet touching the bow on the last model and now I’m using a massive foam block or the Happy Feet fully blown up – at least a 3” difference. Longer legged paddlers will be stoked! Hope this helps – Clay

    I weigh 165 pounds and I’m 6’1. I have an old 2016 large rockstar, but it’s too big. What’s the sizing differences for the 2016 large rockstar and the 2018 medium. I could fit into the medium, but what are the differences of the boats and is it worth it?

    1. July 22, 2018 at 1:46 pm

      Hey Carter! 6’1” should fit into the new Medium depending on how much of your height is in your legs. I’m using nearly 3” more foam in front of my feet and still not touching the bow… there’s much more foot room compared to the 16 Rockstar AND it floats me higher as well! I had a similar issue with the 16 large – felt wide on me – but this new model feels much narrower in the medium… and I predict it will in the LG as well. Good Luck! Clay

I had a similar issue with the 16 large – felt wide on me – so I paddled a medium but that felt pretty small. This new model feels much narrower in the medium but a bigger boat overall with way more foot room… and I predict it will be a similar story between the LG’s. Good Luck! Clay

    Can a Rockstar be setup for a C1 paddler?

    1. July 22, 2018 at 1:24 pm

      Sure – we have many c-1 paddlers using our playboats. We had a special conversion kit but right now it’s outdated so most of our Team are custom crafting their own out of foam. Check in with Dane or Seth Chappell on FB for tips! Clay

    Beautiful boat, love that it comes in three sizes, but you don’t give paddler specs. At 6’3″ and 250 and size 13 feet makes finding a playboat that both fits and floats without the stern sinking is a daunting task.

    1. July 22, 2018 at 1:17 pm

      This medium size is floating higher and fitting much longer legs than last year’s, so while the Lg won’t be seen until a few more weeks I would suspect it will be a great fit! The Mon-star is likely your best option at 250 though – that’s the biggest size we’ve ever made for a play boat. Based on the 2010 Allstar it’s a great design! Clay

  9. Meg Brown
    July 22, 2018 at 12:56 pm

    How much weight do the rock star’s hold? Would they be good for paddling around lake or pond and what about a protected area of the ocean.

    1. July 22, 2018 at 1:14 pm

      Hey Meg – this Medium will float up to 185 lbs easily – I’ve seen 200 lbs paddle it well but it’s slower. Our recommended specs are usually pretty on target, just look for them on the web page. Clay

    2. July 22, 2018 at 1:20 pm

      Any flatwater is good, but they are not fast (6′ long) so they will only be fun to practice play boating tricks on a lake, not for long distance journeys. Longer boats have more ”glide” between strokes and make flatwater go by faster. This will be more fun on ocean waves or rivers or trying tricks. Clay

    1. September 25, 2018 at 10:43 am

      They are out now! I’ll try to post a review soon – its tall but not wide! Clay

    1. September 25, 2018 at 10:41 am

      Hey Ben! Go with the Medium – its awesome and handles more weight than the last version so you’ll have more room to grow. Enjoy! Clay – 175lbs and medium.

    When will the small and large models be released?

    1. September 25, 2018 at 10:39 am

      They are both released and available for order! Paddled both recently, Small is a true small but handles bigger paddlers pretty well, Large feels tall but not wide like the last one – I’m trying them all and hope to answer better in future. Clay

    August 7, 2018 at 10:06 am

    @ 5’11” with my weight ranging between 195 to 205, I’m interested to know what size would be recommended. I have a more muscular build and often have sizing issues with my fluctuating weight. I typically paddle smaller waves and holes because that’s all New England has to offer.

    1. September 25, 2018 at 10:37 am

      For your size I would go Lg if getting air and downriver paddling are a priority, but the Medium will fit you and be easier to throw around. I paddled the Small and loved it even at 175, though it wasn’t as retentive or poppy as the Medium. I also paddle the Lg downriver and can get vertical but it’s a challenge to swap ends compared to the Medium. Try both Md and LG and let us know! Clay

  14. Sam Perkins
    August 16, 2018 at 11:58 am

    I’m 6foot and 150lbs, would like to use for mainly flat water tricks. What size would be best? Should I stick with the 2016 model? Thanks

    1. September 25, 2018 at 10:29 am

      Hey Sam – For flatwater tricks, the 4.0 goes bigger for sure, but at 6′ I’m not sure if you will fit in a balanced way in the Small or not. The good news is you will fit into the Medium much easier! It’s a tall boat that fits taller people no problem. If you can throw the 16 around the 4.0 might take a bit more practice but it’s more a matter of learning to be precise with the angles and committing to the ‘bounce’ from one end to the next. Try a Small 4.0 just to see if you fit but I think that’s going to be tight, or just try a Medium 4.0 and see for yourself! Clay

      It’s an insert, molded into the plastic, not a hole into it 🙂

    September 3, 2018 at 12:13 pm

    There are no weight range specs provided on the website. Would help if there was? At 210 lbs the superstar has been the best option for me so far but it’s just too big. Mediums are always too small weight capacity-wise. If the Superstar is 65
    gallons and too big, most mediums are in the mid/upper 50’s of gallons, seems like the medium 4.0 at 61 gallons might be about right. But other weight related comments make it sound too small? Mediums are the right size for my body dimensions. I’m just big-boned. What to ride at my fav play wave in Boise, ID?

    1. September 19, 2018 at 9:59 pm

      Hey Chewy! I’ll add more when I know more but 2 friends at 210 paddled it today and looked pretty solid in it, right on par with our previous Lg’s before the 16 maybe or just floated better in the eddy. It just came out – hope we get better info soon. Clay

    Im 5’11 and weigh around 55kg and was just wondering which rock star 4.0 i should go for?

  18. Volker
    September 14, 2018 at 5:52 pm

    I am 80 kgs and 191 cm. I bought a 2016 rockstar Large. But I do not have enough weight to have a stable bow stall and flatwater moves take a lot force. Could I fit into the medium? Or will there be a medium/large intermediate rock star size in the Future? Thank you in advance

    1. September 19, 2018 at 9:10 am

      Hey Volker – The 4.0 medium will fit much better due to the extra foot room but in the 16 I would stick with the Lg as the md will be slower and not as retentive at your weight due to your leg length pushing you back. To make the most of your weight in a larger boat, sit up on an extra seat pad or 2 – or push all the beans into the middle of a sweet cheeks. The higher center of gravity makes the most of your strength and technique. Also work on technique by doing lean cleans without a paddle before adding the paddle strokes. Stephen Wright has some great videos on Youtube.. Good Luck! Clay

  19. Volker
    September 15, 2018 at 5:01 am

    I am 190cm (6’4) and 80kg (180 lbs) and Inseam plus foot size = 45 Inches. I Always felt to light for the Rockstar 2016 large I got. How is it with the new medium 4.0?
    Is there hope 🙂 for me?

    1. September 19, 2018 at 8:58 am

      Hey Volker! At 180 lbs I’m understanding, 175 myself and paddled the Medium as the Lg felt really wide unless I sat high up.

      The good news is that the new 4.0 LG is both narrower and taller – so it should feel more sporty and let us sit up higher as well! I can’t wait to try it out – maybe later today on the Dries! I’ll let you know how it goes, we just got the boat in and so many bigger folks have been loving it … so I haven’t paddled it yet. Clay

        October 6, 2018 at 12:02 pm

        Hello! I’m 6’3” and float between 195-205lb depending on the season. I currently paddle the L 2016 but would’t want a ton more volume. Would you still recommend the Large 4.0 for me? I won’t be doing downriver, just small to medium waves and holes.

        Also, does the L come in the same colors as the M colors shown? Cheers and thanks!

        1. October 7, 2018 at 1:14 pm

          Hey Daniel –

          The colors are same as medium but the ‘green’ is now a lemon-lime yellow green mix.
          The sizing.. you can certainly try the medium! I paddled a Small at 175 and it was still really fun and very easy to throw around. The leg length won’t be nearly the problem it was in the 3rd generation Rockstar as this 4th one is longer at the legs by design. I’ll be curious which you like better – the Lg felt pretty good on me at 175, but I prefer the Medium. Tell me what you end up liking the best! Sorry I don’t have enough feedback yet to give you a specific answer but to me you fit the Lg best, but could paddle the Medium if you choose that style now… so give it a go and write back! Clay

      Hey Casey – about half yellow half green as I recall, I’ve searched around and can’t find any shots of it – I know I’ve seen one! I’ll post somewhere when I get it discovered or get one myself!

    Is the new Rockstar large SuperStar sized or Monstar sized?

    1. September 26, 2018 at 11:34 am

      I would say it’s more Rockstar Lg sized than anything else – its thick like the 2010 Super-star but much narrower than any Lg boat we’ve made recently. I paddled it yesterday at 175 lbs and it’s fun! Took awhile to get 10 ends but eventually hit flatwater tricky and loops and macho-moves. Felt about like a 2010 Superstar .. a touch harder than the 15 Rockstar Lg but easier than the 14 Rockstar Lg or 14 Superstar.
      Ask again for specifics, hope this helps! Clay

    Hi! I’m 6ft 2, 195 pounds

    I’ve been paddling the 2013 Allstar and I fit perfectly in it. I’m really debating between the L and M. I’ve read all the comments above but I’m still wondering which one would be best. Any advice? Many thanks in advance!

    1. October 5, 2018 at 3:55 pm

      Hey T paddler: The All-star is a similar size boat as the 4.0 but this one is narrower by far, which makes it paddle smaller. I think at 195 you can paddle the medium if you want a smaller, easier to throw around boat OR you could go Lg for a faster, poppier but slightly harder to flatwater model. At 6’2” you will probably have more than enough leverage to boss around the bigger boat, especially if you sit up on an extra seat pad. Try one and see … I would NEVER have paddled the Super-star from 2013 as it was massive on me, but the Rockstar 4.0 in Lg was a fun downriver boat I could edge easily and still flatwater cartwheel after some practice (I’m 175lbs). Let us know when you get to try one! Clay

    Hi , I’m looking to order the new 4.0 , I’m 5.11 and 210 pounds , which size should I go for ? I’m curantly in a LG 2016 , Thank u

    1. October 5, 2018 at 3:51 pm

      Hey Trevor – I would suggest the Lg for sure, as it will be faster downriver (or back to the hole) and give big loops and honestly, it feels ”taller” than the 16 but narrower … it’s more volume but easier to edge. I think the same size people will like the same size boats (+ 10-20lbs leeway in the new model) as while it’s higher volume, it’s a bigger ”design” rather than a bigger size.

    Hi. I am interested in getting a rock-star. I am 5’5 and 120 pounds. I know the small would fit me better but I want a boat that I can grow into. Do you think I should get a medium or a small? Thanks.

    1. October 15, 2018 at 9:12 pm

      Hey Captain Worrell –
      At 5’5” and 120 the Small sounds great! I’ve paddled it at 175lbs and not only did I fit but I had a blast on Corner Wave. I’m 5’9” and size 11 feet. This small will handle more weight than the last one because its so flared at the sidewalls. Stephen is one of our smallest folks in the Medium and at 145 he throws it around easily. What’s your home river? The medium will be fun loops and surfing – sit up on a Sweet Cheeks 200 to get a better fit in any bigger boat. Hit me back for more details but I would go Small unless you are due to pass 140 this year. More details as I get more team feedback. Clay

    Hey there, I’m looking for a new boat for my husband and will custom outfit it to c-1. We mostly paddle on the Ottawa. He’s 6’4, 195lbs but the previous Rockstar L has always been a little big for him. Since these are going to be a bit bigger would you suggest getting a M? Thanks!

    1. October 15, 2018 at 9:05 pm

      Hey Mandy –

      At 195 I would guess the last one – version 3 or 2016/17 – would be perfect as its wider and that’s good for a tall C-1 paddler. That said – if he LIKES narrow and smaller boats he can fit into the Medium 4.0 easily. Does he have the 14 or the 16 version? 14 was wider and thicker, 16 version was a touch narrower and slicier, 4.0 is narrowest at the chines but a touch more volume than the 14 even. I would stick with the LG, personally, at 195 but its personal preference… hit me back for more detailed responses. my first name @ Clay

    At 6’0” and 140 lbs but an inseam of 34 and shoe size of 10.5 plus I’m only 15 so I’m going to grow a little more. Would a medium be best or a large?

    1. October 20, 2018 at 10:45 am

      Good Question Lucas! At 140 the Medium is a perfect ”grow into’ fit already, even at 6′ tall. The 34” inseam should fit so it depends how much more you will grow in the legs. This version of Rockstar has way more leg room than any we’ve made recently so I think this is the best boat for you and should last awhile.

      At 175lb and 30” inseam I fit into the Small and could paddle it on waves. I’ve paddled the LG too but it was a challenge for me to throw down in flatwater – so I would guess this Med would be best right now. Try for leg room fit and know many of us paddle this new 4.0 with the seat BACK from center so that is pretty normal.. Let me know how you fit! Clay

  27. John
    November 21, 2018 at 6:10 pm

    I’m 6’3” 180 and I tried to squeeze into the medium and yes I fit but it was extremely uncomfortable but I feel like the large is too much volume for my weight any sugestions?

    1. November 24, 2018 at 8:28 am

      Hey John –

      Give me some details on ”uncomfortable”. For starters, this boat is designed seat-forwards, so if you usually sit one-hole-forwards then try middle or one-back. 2nd the hull is narrower so you might be able to pop the seat pad out and sit lower than usual. 3rd – did you have the Happy Feet fully deflated and pulled up around the tops of your heels? When they are brand new the beans are at their fullest – and it takes a few weeks for them to pack together and get a good ”vacuum” hard shape.
      As for the Large – that’s a good option too! I suggest you sit a bit higher than normal if you want to go this route – add a seat pad or add some foam UNDER the sweet cheeks to help push all the beans under where you actually use them. I’ve blown it up, slid all the beans forwards and rolled up the back of mine in a pinch – to help me sit higher when I don’t have any other props around. This will sit you higher and make it easier to get the ends down. Then tighten the backband lowering strap to make sure you can lean back comfortably in the taller cockpit (in case you are more leg than torso). This awesome little add-on has really opened up the larger boats to shorter paddlers nicely.
