Product Description

The all-new 7S Slipstream is a one-board quiver that will adapt to a range of conditions from mushy beach breaks to surfing down the line point waves. This board is a true hybrid, both from a design perspective and by definition of its performance.

OUTLINE: Front half resembles a modern fish and is great for generating speed and acceleration when driving off your front foot. The back half resembles a traditional shortboard with a refined outline and a forgiving round tail for smooth, yet controlled rail transitions.

CONTOURS: Subtle single-to-double concave with vee out through the tail delivers a balance of speed and flow over flatter sections, and responsiveness in hollow waves.

ROCKER: Low-to-moderate rocker is designed to offer immediate acceleration from the take off, and still allow the board to fit into more critical parts of the wave.

FOIL: Refined foil and the performance rail profile complete the design package by adding a very sensitive and responsive feel on the wave.

FINS: The Slipstream comes with an FCSII Reactor M thruster set.

Regarded as the most user-friendly hybrid model on the market, the 7S Slipstream not only makes performance surfing easy, but it will give your wave riding a whole new perspective

Carbon Vector Technology

Technical Info


Carbon Vector

Carbon Vector (CV) construction delivers unmatched performance by harnessing the flex characteristics of epoxy and the strength of carbon. CV combines a stringerless, high-density custom shaped EPS core laminated with biaxial fiberglass, epoxy resin and a distinctive carbon fiber webbing, (positioned on the bottom and around the rails).

The carbon fiber webbing serves to evenly distribute tension across the entire surface area of the board to produce a lively, yet controlled flex pattern with remarkable memory recall. The biaxial fiberglass on the deck serves to add strength and also help prevent delaminating. CV boards feel fast, light and highly responsive in all conditions.

Created by GSI to compliment a range of board models and designs, this construction has proven to have superior flex properties over our other board technologies by up to 20%.

  1. 5 out of 5 Great step up for Kids

    My 10 year old son has recently started riding a 5’7 cv slipstream after riding a Soft Tech 5’8 soft board for about the last 8 months or so and I couldn’t be happier. He had a great time on his soft board but I could tell he was ready to step up to something like this and the difference it has made is huge. He can now turn with ease and get a greater feel for the wave itself and he hasn’t had to compromise his paddling ability too much at all.
    It has a good amount of foam through the nose,essential for paddling ability, yet is lose enough through the tail to allow him to surf to his full potential. I am really pleased and proud of his progress and he is enjoying his surfing so much and that is all I can ask for.
    I would highly recommend these boards for people looking to go to the next level but not too drastically. I think its the perfect next board for someone who has outgrown or out surfing a soft board. Also stoked on its strength too. My lad surfed 60 times over summer and the deck is pretty much unhurt. Thanks GSI

  2. 4 out of 5 1 year review

    I got mine in August of 2015 as a step down from my 6’6 superfish. I have a 6’1 at 31.2 liters which was a frighteningly large drop in volume when I was musing over this before buying (I’m 5’11 175lbs 42 yrs). While I did struggle a bit with paddle conditioning, it was not nearly as bad as I thought. After a month (maybe 20 sessions) I was able to get this board into just about anything from short interval grovel windswell to nicer long period chunky barrels (OBX, NC). I used this board almost exclusively through the fall of 2015 and again in the spring of 2016. This board has been smacked down by lips breaking into 2ft of sandbar, has danced with me through the washing-machine and had a few elbows and knees thrown at it :) I love the thin, flat deck and the combo of hard rails with smooth round tail gives you the ability to sink the rail and make nice long round carves (good for cutbacks at the end of A-frames). Only negatives are the lightness (we almost always have wind…which can be a problem with strong offshores or ‘devil wind’ coming up the face) and I have a few spiders on the rails which have required some minor ding repair (expected after beating on a board for over a year). Also, now that I’m better (maybe intermediate to advanced now), I do find this board a bit ‘neutral’ when really trying to push out fins and make hard slashes…it is smooth, but compared to some of my more performance boards, requires a larger arc for turns. Also the larger tail can get a bit ‘slippy’ when pushing hard/ or really steep walls (quad helps but makes board ‘tracky’). Now that I have had the experience of P/U, Epoxy CV, Firewire (both LFT and standard), I really am impressed with this board’s flex characteristics and durability. Just as good as LFT, at a fraction of the cost.

    board shipped swiftly and ding/dent/damage-free! amazing. i was hesitant to buy online bec of fear of damage during shipping. board was packaged real well/secure. havent been able to take it on decent swells, but had fun and amazed at how easy it is to paddle on 2-2.5 ft mushy/onshore/crumbling waves. lots of drive after the popup and first turn. cant wait to see how well i can do on a decent swell

  4. 5 out of 5 7S Cv Slipstream

    First rode one on Costa Rica (6’3″) and had a blast! Came home and decided to get the same board… It rides really well. Fast, paddles great and quick & light on the turns.

    Love it. Have used it 4x and found it really fast. Great to duck dive. I am 84kg. The wide nose makes it very easy to get up on also.

    This board rides great, a lot of volume but doesn’t feel like it. Super light and lively, loose, and fast. Board rides just as advertised by Richie lovett

    Very fast and easy board, love the feel of the CV.
    Surfed this board in various conditions from weak onshore as well as nice clean and hollow waves and I am impressed by the enormous speed the board creates.
    Nice and fast with very good grip with the standard fins and even faster and much looser as a quad set up which I prefer for this board

    The board is super easy to paddle and really takes off upon impact. It’s fleet under feet and responds quickly when changing direction. The FCS II Reactors are a good complement to the board in this regard. In addition, what’s even more impressive is the board’s resiliency. I’ve taken it out on several long sessions and still don’t have any compression dents. Well done, 7S and GSI!
