I'm a bit heavier, about 64kg, myself and the key to highwind controll in my view is a smaller board. Putting a too small fin on a larger board is not going to help, as the board will not have a proper position in the water. It will just feel like it sticks more to the water. If you don't have any waves in your regular spot, then go for a freewave/freestyle wave type of board with single fin or single fin with trusters. Older single fin boards are usually very good for this type of sailing too, as they where were designed with heavy weights in mind and are therefore quite "gunny" in the smaller sizes. anything around 80 liters, ? 56cm in width, should do fine.

Hi,

The sail range for the AtomIQ 104 is 5.0 to 8.0, so 4.5 to 3.6 is not really a sails for it. You can go until 30cm on this board with 5.0; If you need really a smaller sail than that I recommend you then another board to enjoy like Kode Freewave 81.

Hope this help

All the best

Waterstarting a small board is a lot easier. Don't be afraid, youll learn it on your first session! Its that easy when you have the right equipment for the conditions and you'll accelerate your overall skill progress at the same time.

Fully agree with the aboxe. Anyway at 56 kgs you can still uphaul on a 80ish board, but waterstart is so much better in strong wind. You can really learn it in one day. Long time ago, I've been using a similar combo in Leucate: 3.7/4.3 sails, 108L board, 28 cm fin. It was manageable with my 68 kgs but I had much more fun after switching to 85L.

Hi,

The Atomiq 104 is 70 cm wide. It is not realistic to use such a wide board in 40 knots of wind for a super light 56 kg rider, even with a 3.6 sail and 30 cm fin. You will be blown away because of its massive footprint once the nose is lifted in the air. It will be nearly impossible to keep the nose down because you are way too light to keep control of such a wide board in 40 knots of wind. Forget it, it's not going to be fun at all.

There is a very simple rule in very high wind : keep all of your gear as small as possible, especially if you are a super light weight rider. Small board, small fin, small sail, short boom and short mast. This is the only way to keep control of your gear in 40 knots winds. Too big a board will make it more difficult to keep control during a jibe, bouncing out of control during the carving turn, or flying the nose once lifted by a wind gust from below, flipping your board like a pancake and throwing you over the handle bar...

Waterstart is much more efficient, quicker and much less tiring than uphauling your sail in 40 knots of wind.

If you really want to have fun riding those 40 knots winds, please get the smallest board, fin and sail as possible. Think about a 53-54 cm wide board like a second hand Kode Wave 68/67 or a brand new UltraKode 72.

As an example, please find below the real world upper wind limits for my 65 kg body weight :

Carve 111 (63 cm wide) : 25 knots with a 5.4 sail + 26 cm fin. Way too bouncy in higher wind.
Kode 86 FSW (59 cm wide) : 35 knots with a 4.2 sail + 23 cm fin. Way too bouncy in higher wind.
Kode 81 FSW (56 cm wide) : 40 knots with a 3.6 sail + 18 cm fin. Way too bouncy in higher wind.
Acid 62 (50 cm wide) : +50 knots with a 2.8 sail + 20 cm fin. No wind limits yet.

Uphauling a sail in lower wind limit according to board volume + body weight :

A simple rule tell us the following :
Body weight (kg => liters) + 20 L = floater
Body weight (kg => liters) + 15 L = semi-sinker
Body weight (kg => liters) + 10 L or less = sinker

This rule translates to the following results below when uphauling a sail in lower wind limits for my 65 kg body weight :

Carve 111 + 7.7 sail : no problem. Very easy.
Kode 86 + 7.0 sail : still a floater but this is the limit with feets getting wet. Moderate difficulty : I must pay attention not to sink the nose nor the tail.
Kode 81 + 6.2 sail : semi-sinker up to ankle level. Difficult to keep balance once submarine.
Acid 62 + 5.5 sail : sinker up to waist level. Very difficult to keep balance once submarine.

For your 56 kg body weight, a 76 liters board will be just enough to float you so you can uphaul your sail in case of a wind lull.

Cheers !

JM
