hi
i am foiling SC and formula 178 board. weight ~95kg. sails 4.8 to 8.6.
looking for lower wind setup.
what about 2400 front wing with the formula board and 8.6 sail? is it significant change over the regular 1700 wing of the SC ?
cheers
You are close if not past the point of diminishing returns in terms of wing size vs low wind speed foiling because of the increasing amount of drag by going to a bigger wing. Especially with using a sail in the 8s already.
What would you call your wind range presently?
It seems like you have a race board, race sail and you want to put very soft and manoeuvre oriented foil under it.
Why not put a Starboard Race with a 1000 or 1100 wing? I think the set will be a lot more balanced in the end.
I have to agree about the diminishing returns comment above. For all foiling I prioritize getting the board going onto its own planing speed before lifting up into flight. I weigh 94 kg. My various foil wings run 779 cm2 and 1120 cm2 for the AFS-2, and 940 cm2 and 1300 cm2 for the LP. Sail sizes are 6.4 and 7.0, sometimes 5.0 when it's windy.
The LP 1300 gets me a slightly lower flight threshold than the 940, but not enough to matter. So, I just ride the 940. It works.
The AFS-2 1120 makes a big difference over the 779 for ease of riding.
In Florida I have the i76 and used to have a 1100 cm2 foil. They both ride the same even though the i76 wing is a lot bigger.
Point is, in my experience, anything over about 1100 cm2 is a diminishing return, even in light winds. Yes, people do ride the really big i84 and i99 with big sails (8.0 +) in the light stuff, but I can hang with them just fine with a 940 or 1120 and a 6.4 or 7.0 in the same light stuff.
If the wind is less than about 12 mph consistently, there is not enough energy in the wind to foil with anything. 10-12 mph is a slog. 13-15 mph is foil central. 8-10 mph is wishful thinking for us duffers.
I need 9 to 10 knots to fly with an 8,5 Ezzy Hydra, a 1050 Freerace wing , 85cm fuselage and a 91cm wide foil board. I weigh 90 kg. I can fly at 8 knots but it involves a lot of pumping and usually i am too lazy to do it. In 10 knots I can take of with a small pump. Flying through lulls of 7 knots is no problem.There is a correlation between board with and sail size, the wider the board the bigger the sail needs to be to take off in lower winds.Non foil sails have a much higher low end than foil sails. Formula boards need a much bigger effort to get going than foil boards. Latest versions of foil boards can "pop" before getting to the planing fase.
I don't think upgrading your wing will help a lot. Practice pumping and take off will do more I guess. Also make sure you move mastbase and straps far enough backwards to ensure the max lift.
The supercruiser is not designed for 91cm or 100cm wide boards. It does take off with low speed so that can be in your advantage. However it remains necessary to get to a certain speed to take off and the width of the board is not helping you. A 80 cm board and 7m sail will get you going in 14 knots also......
I guess things depend on a lot on your entire setup, and on skills. I'm around 90 kg and see quite a bit of difference between the i84 (2066 cm2), i76 (1534 cm2), and Time Code 68 (1101 cm2). With the i84 and a 6.5 m sail, I need about 11 knots averages and 13 gusts to foil, and 12 knot averages are easy fun (numbers from meters ~ 10 m in the air; numbers measured on shore are 1-2 knots lower). With the i76, I need about 1-2 knots more, and another 1-2 knots for the TC68. The bigger differences are when it comes to foiling through lulls: the large the wing, the easier it is to stay on the foil. My pumping to get going is pretty poor. Better guys of similar weight can foil in less wind and/or with smaller sails.Select to expand quotefelix1111 said..
i need 14 knots for foiling with 8 meter sail
Unless you're using a meter that reads high, there seems to be quite a bit of room for improvement. Our weights are pretty similar, and I'm nicely powered on 5.6 on a similar sized foil (i76) in 14 knots. This could be a setup issue. My light wind sessions became more fun after I put tracks in my board so I could move the foil forward about 10 cm. On the SB setup, you may be able to get a more balanced setup by adjusting the angle of the stabilizer.
The other issue, to paraphrase Brian Talma, is to "ride the foil, not the sail". Using relatively big sails for the wind conditions makes is hard to develop a good feel for the foil, which really helps extending the lower range.
I'm 90kg plus neoprene and in 14kts the Supercruiser can work with either a 5.2 or 6.4 depending on how much I want to pump.
I'm using a fairly narrow board without a lot of tail volume so I need a little speed to get into flying position.
What wing and mast base position are you using? That big rig is likely keeping the foil pressed down and unable to pump properly.
Excuse the length and lack of action(and probable interest to anyone but me) in this video. Recently I changed from the Super C to the Race set up with the 1000 wing. This is the clip is foiling on the first decent conditions for this new set up. *Note: I have since then rectified the constant touching down with some tuning with the mast foot. I think it can be seen here the wind was not strong but I can get up with some pumping - and is some cases it comes up with a bit of slop assist e.g. 1:35 - barely any assistance from me. Big wing foils like the SC are awesome for waves and are designed to be swell responsive- not cutting through like the Race foils. This is why in those condition it is a fantastic set up and you need the drag. I changed to my current setup because I wanted to cover more distance with more speed. I still have the SC and might keep it for bumpy seas because it is great fun.

mast 1/3 from back. the rear wing is set for minimum wind.
I don't think that board has the mast track far enough back to use the SC foil in its regular configuration. But if you mount the front wing in it's more forward setup and put the stabilizer in the center position you might get it to balance. That is what I use for lighter wind. I only use the wing in the normal position if I'm on a 4.7 or smaller and that is with the mast base as far back as a single bolt base can get me.
I would give the 2400 a go, I think it would go in less wind than the 1700, you could have some fun on that, let us know how it goes if you do get it
Hey there. I'm quite heavy, 110kg on a good day, and been foiling in a slingshot set up last season. I'm really enjoying it and keen to get a starboard kit in the hope of competing. I'm just not sure what foil is the best one given my size? Anyone got some reccomendations?
