Indeed, a while ago on this forum I was recommended to use super small boards (60-70l) at my weight in high-winds. The problem with my spot (Hong Kong) is that the wind is extremely unstable and gusty. In order to get to a more stable windline, I have to exit the bay and then it's full open water. I much prefer this as the wind is much more stable and you can launch off some great breaking swell.
I've been caught out once or twice even outside of the bay where the wind has dropped to less than planning conditions which is why I'm not opting for anything smaller than 95l for the moment.
I've gotten a 32cm fin for my board which is 63cm wide and when nicely powered up the board is perfectly balanced with the outboard straps, no need to dig my heels in to keep the board flat. I have yet to try this fin out in over powered conditions, but for the moment it's much better than the 36cm.
Thanks for your advice.

The more I think of your 36 cm fin, the more I find it way too large with a 5.8 sail when overpowered in 6-7 Bft for your 54 kg rider weight.
For illustrative purpose, this is what I'm using with a 5.4 sail in well to over-powered up 20-25 knots of wind (all 4 footstraps outboard and back):
-Hypersonic 105 (77 cm max width/54 cm width OFO): 26 cm slalom fin. A 32 cm slalom fin is too large.
-Carve 111 (63 cm max width/40 cm width OFO): 26 cm slalom fin. A 32 cm freeride fin is too large.
-Kombat 86 (59 cm max width/39 cm width OFO): 24 cm wave fin. A 30 cm freeride fin is too large.
BTW, I'm on Acid 62 + 4.7 m2 wave sail + 20 cm fin in true 6-7 Bft (25-30 knots wind). The stronger the wind, the smallest the gear should be picked up for a light weight rider to still be in 100% control when fully lit in choppy seas. The Carve 111 is for sure too big with a 4.7 sail for me whereas the Kombat 86 is still barely manageable with a 4.2 sail up to 7-8 Bft (2 front straps inboard and front; single rear strap centered and front. All 4 footstraps outboard and back was just impossible to keep sailing the board trimmed flat & fast).

I'm trying a 32cm today, I think it should be much better.Just put side by side, my 36cm and the 32cm seem to have an even bigger difference in size than 4cm, and the 32cm is much lighter. I'll post back on how this setup works.

I find that for your XS weight, a 36 cm fin is way too large with a 5.8 sail.
Never run that JP but I did use a Starboard Carve 111 with her stock 32 cm fin and a 5.4 m2 sail but the stock fin was way too large. A 26 cm slalom fin was a perfect setup up to 25 knots for my 65 kg, so I surmise the same should be fine with your 54 kg as well. A 36 cm fin was recommended for a 7.4 m2 sail on the Carve 111 BTW, so I'm pretty sure there is something wrong with your fin sizing setup.

I had almost exactly the same straight line speed as my friend on an Exocet S-Cross with 6.3m and a 36cm fin so I'm going to try the following to gain the extra bit of speed I need to leave him behind me:
- Mast track middleish/back (and tighter so it doesn't slip forward)
- 4 cams on my sail instead of 2 ( theoretically it can be rigged 3 or 4 but taking out the top one was fine so I tried it)
- All footstraps back 1 knotch so 2nd most back position
- More outhaul (when I got back to the beach I realized mine had come slightly loose...)
- Smaller fin (I'm trying to find a 32cm fin as my 36cm is seriously impeding on my top end. Also, as the guy I'm up against has a 36cm fin and weighs more so generally has bigger sails logically I should have a smaller fin)
I think that with all this I should gain at least 3 knots in top end.

I'd like to put in few more comment on foot strap positions /fin size, etc..
mine always all the way back with relativelly large fin, if you have problems/tail lifting,
you have choices: moving mast track forward, smaller or better fin, moving
foot straps forward, specially front ones (makes your stands wider),
all of those things will de-power you set-up but will give you better control,
so final result could be actually a better avg. speed,
as your tecnique improves, you'll be able to move all settings back again.

As for posting on this forum, it's the best one on the internet for windsurfing info.
