I just bought a futura 133 2009, a very nice board ,and I am using it mostly with a severne element 8,5. Before I was riding a formula 162 with a NP 9,8, but i decided to improve my freeriding abilities and also it was quite demanding phisically speaking, I did not race. So sold the board and sail

The futura is quite good plannig when powered up, though in marginal winds, is not as good as formula, planning early and upwind ability. that we know for sure.

I wonder if for those situations I upgrade to a bigger fin, let`s say 50 or 52, will the board improve in planning early and upwind performance, i don`t want a bigger sail, because I know for that I will end up again in formula boards and heavy sails.

As the tail width is only 49cm you will over-power very quickly on a 50 - 52 fin, otherwise known as snapping your ankles as you wont have sufficient leverage to keep the board in the water

Thanks for the answer, then I`guess I will stay on the beach when the wind is low.
How many knots do you think will need a decent rider for plannig with SB F133 and 8;5, let say 80 kg. I would say 12knts ??
Thanks again

I would disagree with 628. While I haven't sailed a Future 133, several years ago I raced a bic techno 283 which wasn't as wide as the futura. It came with a 48 fin, but I added a 52 and 54 for my 8.5 and 9.2m sails for light wind planing and upwind performance. The 54 fin was good up to about 15 knots, the 52 was good up to 18-20 knots and then I put on the stock 48 fin.

I lighter winds, I believe a 50 or 52 fin will make a difference on the futura. I weigh 79kg

Just as another point of reference, I tend to agree with Ken. Although my reference point is an older Mike's Lab course slalom that is only about 60cm wide, I was matching a 50cm Tectonics Mirage with an 8.1 race sail with excellent results. The kit had a great low end, but I was also real comfortable in average winds up in the 15-18 mph range. My weight is approximately 75kgs.

Lastly, the product specification for the Futura 133 does reference a potential fin size up to 50cm. Although the large fin size probably was most likely spec'd to match up 9.0-9.5 sail, I'm sure that it should be suitable for an 8.5, especially if lighter winds are the target.

I should add that for the last 25 years I have raced longboards, course slalom and formula on upwind and downwind courses. I have always tried to maximize my planing and upwind performance with the largest fin I could handle, so I am pretty used to and like the larger fins. However, if free sailing is the main focus with only earlier planing as the goal, I would recommend a 50 or 52 without hesitation.

Your body weight makes a difference. If you are in the 90kg range, you could go bigger.
