Default Wave board versus Slalom board

I was yesterday afternoon out in 25-35 knots with huge, nasty chop.
The autumn winds are finally coming in strong with us.

I started off with my IS87 and my North Warp 5.0 sail.
Struggeled for more than an hour.
Just couldn't get my gear under control, mainly because of the chop.

Because it was already getting late (darkness within 2 hours), I decided to do a little experiment.
I took my old school 85L Naish wave board out of the trailer and put the Warp 5.0 on it.
Yes, that's right, a full blown race sail on a pure wave board.
And guess what, I had a great remaining evening session with lots of control over my gear.

Conclusion:

1. There's "night and day" difference between a wave board and a slalom board of approximately the same volume. The main reason for it, I guess, is probably the thinner and narrower tail of the wave board in combination with a 25 wave fin in stead of a 28 slalom fin.


2. Race sails can also work on wave boards.

Yeah many of us use real wave boards for straight line blasting in crazy chops. Did use freerace sails too but I prefer one with a smaller foot. As the tail of the board is much thinner, the sail will sometimes touch the water when you close the gap. This may be fixed by adjusting the mast track but you know... there are many fast enough wave sails in the sub 5 range.

No question, going for a wave or bump & jump board (in my case) will smooth out the chop. I too made this same transition last week when it was building from 15+ knots to 20+ knots. My 6.6 race sail on my iS 111 was fine until the chop was killing my legs and back. I pulled out my HiFly bump and jump board (same volume and width as the iS) and sailing was much smoother. The narrower tail, the V bottom and greater rocker all made things easier on the body, plus it added control.

This was my first time with the 6.6 race sail on the HiFly since I always started with my 6.0 no cam sail with this board. I got lazy and rather than rig a smaller sail for the board, I tried the race sail and it worked fine. Not great at gybing, but nevertheless a good option to keep me on the water longer. I should also add that I was able to attain a higher top speed with the HiFly. More wind so more power, but also rougher water.

Yes, it's good to hear that I'm not the only one who needs to fall back to a wave board when the going gets tough

Yesterday, I've examined more closely the tails of my wave board and my slalom board (IS87).
I did not expect that much difference with these low volume boards, BUT there is !
The tail of the wave board has a really sharp and pointy end, whereas the IS87 has a more round end (+ cutouts of course). Then, beside being very narrow and pointy, the tail of the wave board is also very thin (small height). The latter is probably also very important to smooth out the chop.

Outside of my speed spot I often sail a RRD 85 with a 6.0 Hot Sail Maui Speed Demon, mostly because the RRD makes for a good moderate to strong wind board as I use it 4.7 to 6.0. I personally find a slalom board more comfortable above 6.0 because it erases swell/chop in those conditions. Below that it is unquestionably more work to be out with a slalom, and speed is not that great either, if your are sailing overpowered in heavy chop with a 4.7-6.0 and free-style wave board a slalom will not be much faster. However drop the wind a bit, and take away some chop it will smoke by.

Amazing how this compatriot is using his IS80/2011 in "heavy conditions".

That's rough!!!! but it also brings home how speed is very limited in those conditions.

I am not at all indicative of what it can be done by pushing things to the limit (i.e. I am VERY far from pro level) but I might be indicative of an experienced sailor and I noticed that my max/average speed is strictly dependent on water conditions. Typically in 6.6-7.3 conditions I hit above 30 knots but below 34-35. Twice I was lucky enough to be on my 5.5 Hot Sails GPS in 20-25 knots in very flat conditions and I hit my max speed ever (37-38) I probably would have gone as fast with a 6.0 or 6.6, and a big guy with a bigger sail could have used bigger slalom and go as fast.

Add a bit of chop and messy water and I am below 30. My Acid 74 with a SuperFreak UL 4.7 (not a sail known for speed) hit 28+ a few times and I doubt I would have gone much faster with any other gear in those conditions.
