View Full Version : 100 kg on a hypersonic 105?

1st June 2010, 12:22 PM
Hi, there is a 105litre hypersonic for auction here, for US$250. Cheap enough to buy for a laugh, but just expensive enough to ask your opinions first.

My problem: I am 100kg. This means I will be limited to waterstarts, which in turn means it will be a board for medium to strong winds only.

Can anyone tell me if this board will suck for such a heavy guy like me, even when I am in strong enough winds to waterstart?

I should add I already have a Carve 121 which is good for me in lightish to medium winds, so the hyper would be for when it blows properly. Tell me, will I have fun?

Very interested in your responses...

They Hypersonic hardly makes sense as a heavyweight's highwind board, as a partner to a Carve 121.
In your shoes I would instead look for a freeride or Freestyle-Wave in the 100-105 liter range (60-65 cm in width). It will be a waterstart only board that takes you well into 5.0-5.3 sail territory.

Hi Ben

Mention "Hypersonic" and you'll get a real mixed bag of responses:) Like Marmite, people either loved it or hated it. For sure, it needed a different approach to get the best out of it c/w normal slalom boards. But once dialled, it was a shed load of fun:) The HS had a big range and is probably the only "one size for all" slalom board, great concept in its day.

The MK1 HS was one of my all time favourite boards. I had a D-ram 125 and a wood 105. Other than big sail slogging, the HS125 felt pretty similar to the HS105. I was using Gaastra Nitro's then, and used a 5.5m to 9.3m on both the HS105/125.

Now a days, a 5.5m on a 78cm board would be considered wrong as boards this wide are XL slalom. But the HS's huge double concaves allowed you to run on small or large fins, partly were its huge range came from. 9m sail, 78cm wide board and a 34cm fin (todays XL slalom can not do this) which mean't "fast" downwinders:)

It was very good in chop as its huge double concaves made feel like it was riding on a cushion of air, very comfy for such a wide board.

Not sure what type/size sails your on, but the HS likes cambered sails. A 7+m would really be the smallest size for the HS105. But this combo will take a lot of wind, 15k to 25k winds.

At 250, it could be cheap fast thrill's (in a good way):)

Thanks guys,

I get the feeling the hypersonic is one of the great boards of all time, or at least one of the most influential... I should buy it and stick it in a frame behind glass and hang it on my wall for future worshipping. The fact some people hate it just makes it more brilliant if you ask me. It took alot of balls for SB to make such a radical design for its time.

Thanks PG for pointing out the downside of this board for me, but at $250 (ie virtually free) those reasons are not enough to cancel out what Mark H is saying.

But yes PG, i will look out for a board like you suggest if I can get one this cheap. For real strong wind I currently use an old 80 litre wave board. It weighs nothing, I love it!

Hey Bro

Get the board. Make sure you have some cammed sails. Even if you hate it at 1st, keep perservering, as you will learn more on the Hyper than any other board. As you get better on it, you will plane up earlier than your carve!..

Enjoy the challenge

2nd June 2010, 10:46 AM
OK Maximus... I will!

If it truly does plane up earlier than my carve I will be blown away. I guess it makes sense though if it's wider, and those concaves must help stop the board sinking at low speed.

Or is that an embarrassingly stupid and naive theory?:)

2nd June 2010, 11:15 AM
Everything Mark writes is correct. But at the same time I believe that Mark is significantly lighter. And that makes a difference.
On the other hand, you already have a small board to use when it really blows (and the wind is steady!). Go for it, you can sell it for half of what you bought it for, and it is still not an expensive test.

With all the light winds we've been getting this year in the UK, I wish I was lighter:) I'm 105kg & 194cm

you fat b...stard!

3rd June 2010, 04:36 AM
Actually Mark you are identical to me in height and weight (100kg was just a rounded off figure)... we are both perfect physical specimens in other words. I should listen carefully to everything you say from now on... I will go back and read every gem you have posted in the past too.

One thing I never understood was: Is bigger model of the same board optimised for a bigger sailor in the same wind, or an average sailor in less wind. Maybe that's another thread though...

Actually its a little harder to get planing because of the concaves, on the upside it glides longer through lulls, and points very high on autopilot. Great entry into the slalom world, which was its intent.

When you get it, let us know and we can all give you some great tips to get the most out of it quickly,

ok, thanks maximus, I will definitely do that... ben

Newsflash, I have purchased the board. If there is any dissatisfaction upon delivery all the above contributers can expect to be sued. You have been warned.

Oh dear, I was only joking when I said the HS was great. It actually a terrible board, sold mine after just one session:))

I have used the Hyper, I have seen the light... unfortunately it was in gusty (to put it lightly) conditions, going from 2-45 knots every 20 seconds. But, in those 20 second bursts of wind I can report I found it easy to control, it pointed very high when asked, and any chop just seemed to melt away as I hit it. Top speeds were impressive the few times I managed to get my back foot in the straps before either the wind stopped or my heel clipped the water and sent me into a catastrophic failure of geometric orientation (crash).

Great news, it came unexpectedly with an awesome board bag and a mast base and extension. US$250 all up.

Question to all you good guys out there: Should I move my back straps one setting further inboard? I have massive size 13 feet (perfectly in proportion with the rest of me... settle down ladies...) and wear booties. I managed ok, but usually only by putting the back foot in first. Otherwise my heel would drag in the water to disastrous effect if it happened when I was already planing...

29th June 2010, 04:20 PM
I would reccomend running the front and back straps in the middle setting. In regards to the back strap, best to start with the inboard setting until you get used to sailing it, then down the track try the outboard setting again. However with size 13 feet, this may be the only reasonable setting.

30th June 2010, 07:05 AM
thanks Maximus, I'll do it now and see how it goes...

6th July 2010, 05:50 AM
well, turns out i can't move the rear footstraps inboard, there are no screw holes.

But I had a great session yesterday anyway. I just have to get the back foot in first before the speed gets too high.

But all you HS fans out there, I have some dire news: Yesterday's session was in outstanding conditions. Smooth, strong (perfectly to slightly over powered on my 5.9m sail) wind. I started on the Carve 121 to assess the wind, then got the Hyper out of the van. The Carve had been flying at good speed (about 31knots) so I was hoping for something special once I got on the Hyper. Unfortunately I couldn't seem to make it scream. I had a few crashes but that was expected, getting used to the new board. It went fast, and smooth, and high, but even on my good runs it didn't seem to really fly. After half an hour I got back on the Carve for a comparison and it was instantly obvious I was going about 4 knots faster, and with better control.

I will not blame the Hyper for this, as it is surely a faster board, or people would have been winning slalom events on carves back then.

So what do people think caused my slowness? Unfamiliarity? Not enough volume for such a big lump of meat like me? The fin? (my carve has a beautiful 42cm c3 venom, the HS has 30cm dodgy looking drake fin that looks like the tip has been chopped off square, although I believe they came like this with the hypers...)

Hi Ben, the original HS fin was a weird looking one, easy to use, but not to quick. The two stock HS fins were 34cm and 42cm (i think). Your venom will take the HS up a gear or two for sure. HS likes plent of downhaul two get it to fly. And it not to heavy on the back foot. Then you will be fast:)

6th July 2010, 07:15 AM
Hey Kiwiben

To answer your questions, I believe its a combination of all those things, unfamiliar, poor fin and tuning. Ideally when you get a new toy, best to aim for moderate conditions, where you can tune your gear. Volume isnt a problem


Mark is right about the stock fins, not that great, and the small one should have been 34cm, if its chopped down, it will be worse than the original. get yourself a venom 34 for your 5.9 to 7m sails.


As the tail width of the hyper is significantly larger, you will need a higher boom (At least nipple height for you) & longer lines (26-30", adjust slightly backwards of where you would use for your carve, gets the rig more upright and away from you) to get the same sailing position as the carve. . A wider tail means you can also carry larger fins and sails. You can run a 8.6 comfortably on the hyper. Set your mast base on the centre position, downhaul your sail to max, control the power by adjusting your outhaul. Most likely if your using a 5.9 on your carve, odds are you could be using a 6.5+ on your hyper. (bigger tail requires more power, ie larger sail in same conditions)

Here is a guide as to what fin sail combos will work for you:


Personally I would be ringing its neck with the 2 larger sail sizes, before using the smaller ones. There is no reason why you cant do 31/32 knots off the wind with a 8.6 on it.

6th July 2010, 11:24 AM
That sounds awesome guys, I will do it all next session... thanks for your time and thought, much appreciated...

One question though... If my 5.9m was beautifully powered up, wouldn't a 7.5 have been overpowered? That is probably a dumb question... but I have been operating under the belief that sail size is governed purely by windspeed and adjusted for bodyweight. I got this belief from using James Douglass's sail calculator. If this is not the case then this is truly a useful revelation for me... thanks again

6th July 2010, 01:06 PM
Depends a lot on your sail types, I am commenting more on race or free race sails.

6th July 2010, 02:19 PM
Totally agree with Maximus that the HS will carry a good sized sail in strong conditions. Hyper though is a balancing act - need sufficient fin and sail to get it flying, but past a point when drag sets in with the sail / fin it is time to change down and go faster. Go down a fin size first then the sail if it seems you are hitting the wall too soon. Anyway that is this punters take on the HS - great sailing but as Maximus says likes to be tuned.
