Default 70cm fin for F-Type 158?

Hi there! Need an advice.

I'm using my F-type in 3-9m/s wind and a little choppy water with Gaastra GTX 10.5m2 sail. My weight is 70kg. Will I benefit in perfomance by upgrading my stock "Drake R13 Race NR 640" to "Drake R19 Race NR 700"?

Early planning in lightwind is what I'm looking for.

Thanks in advance, Max

Yes.

Sailed the F-type 158 for more than a year. I used mainly a Drake 70cm fin with my V8 10,6.

F-type 158 is not the earliest planing board in the world, but the bigger fin helps somewhat.

By the way, even in 8-10 m/s wind, I never experienced the 70 cmfin to big.

I believe the stock fin too small, no problems at all using a bigger fin.

Best regards

I sail a freeformula 158 with the drake 70cm fin. I too have never found it too big. In fact it is the only fin I use on the ff158. The 64 never seemed to be enough in the marginal winds and for cranking upwind.

I would recommend upgrading to the 70 - it is worth it.

I sail it with a nx4 10.4 and a retro 8.5.

Hi kimax,

Yes this will help, but the R19 70 is probably to big, I recomand you the Drake R13 70 or the Deboichet R13 70 soft rake + 6cm.

All the best

Thanks mates. There is just one guy with "R19 70" who wants to exchange for high-wind fin... and I'm considering it.

Hi KImax,

I never try the R19 under this board, just remind you that we made this fin for early planing for a real Formula, so it might be too much powerfull for this board.

But the R13 work really weel.

All the best

Hmm, thanks Remi. Then I better give it a try before doing the change. Just waiting when temperature in Finland goes above +6C... =)))

What actually it means in practice "too much powerfull"? Difficult to handle? Flying board nose?

Anyway I start thinking about switching totally to real formula gear. But F-type goes relatively well on beam reach which is nice sometimes in recreational sailing. I've heard that it is almost impossible on Formulas.

PS: Drake fins are the best!

I've had an F-type for a year and now an F160.
The F160 comes with a Drake R13 70 cm and works realy great!

But after I damaged that fin I borrowed an R19 70 cm, the one that comes with the F161.

Correct me if I'm wrong, but the R19 seems to have more rake and feels a bit stiffer.
With a wider F161 (more leverage) that stifness might be good, but under an F160 I prefer the R13.
An F-type is a bit more narrow 1 feet off compared with an F160, so I think that the stifness of an R19 would be more of a problem then.
No science, I'm just reasoning. So correct me if I'm wrong!

Kimax,

Reaching on a formula board is no different than any other board. Formula racers rig big sails for maximum deep downwind speed. If you are fully powered deep downwind and then try a beam reach in the same wind conditions = YES you will be way over powered.

In 15 -20 knots, I may rig a 8.5 just for beam reaching and free sailing. However, if I was going to be in a formula race, I would rig a 9.2 or 10.0 for upwind and downwind speed. Normally, there is no or very little beam reaching on a formula course course.

While the Drake 70 fin that came with my F160 is a good fin, I find that the Deboichet R13 70 medium (don't know the rake) is much better in winds over 15 knots. I weight 80kg

"Better" means that control is much improved in the stronger winds.
