    I was unable to post a picture. At 4.7 Mb too large...If the moderator can recover the photo that actually downloaded and resize it I would be greatful. also what size is allowed?

    I am totally unable to post here in Cuba with this computer. Can you give me an email to send posts to please. That seems to be the only thing working!

    Although editing this one seems to work, so maybe I'll just keep editing it forever.....

    The size limit on image uploads is about 1MB. It’s a shame the forum software doesn’t tell you this when the upload fails. I have no access to uploaded images.

    Well, my fin is a success! Before lunch I sailed with my low wind kit here in Cuba. A 7.3 sail, a 130 l. Bic Techno board, and a HUGE weed fin. The wind averaged 14 to 15 km/hr with disrupting waves. I never quite managed to get on the plane. Then, after lunch and after replacing the fin with my new home-made fly fin, I tried again. Same wind meter, same 14 to 15 km/hr. wind, same very sideshore wind. I could plane all over the ocean! Some effort necessary to get up on the plane, but pretty effortless sailing after that. The wind was so weak it was impossible for me to beach start in chest deep water with the 7.3 sail. I was starting that deep to be sure not to hit bottom and break my fin bottom before I even had a chance to test it....

    More important; the fin sailed almost normally: in the footstraps, sail closed almost to the board, hiked out over the water, and no spin-outs! After the nose pearling, windward rail sinking, water splash, centerline upright stance, and huge spin-outs of the FRP fly-fin, this adaptation was amazing! As I predicted, the main problem with the original fly-fin was sheer lack of size to do the job.

    Now I shall try the fin with some changes: 5.5 sail, different mast position, different angle of attack for the wing on the fin, etc.
    Also now the board points very well into the wind. Something the fly-fin could not do! 16 kiters sat on the beach waiting for more wind. 4 kiters were on the water but had trouble returning against the very side-shore wind.....

    O.K. First problem with the fin. Today the wind was gusting 17 km/hr to 27 km/hr (with the wind meter set on average setting!) I was overpowered at times with the 5.5 sail, needing to hook in the harness and get back foot into the strap BEFORE lifting the sail to waterstart. I have very little practicing with wind that strong. Anyway, the fin was NOT allowing me to jibe successfully. The pressure on the outside rail would work normally for about 1/4 of the turn and then the board would suddenly turn vertical and sink. I spent way too much time in the water uphauling or waiting for gusts to come again and then trying to fix my sail which is old and breaking apart on me, and then switching to a 4.1 sail. Hopefully, I'll get some steady wind and figure out how to jibe.

    Low speed jibing with the board flat on the water the day before was not a problem. Tilting the board enough to steer at any speed was not a problem. Tilting the board at the end of a low speed jibe to bring the board around and finish the turn was not a problem. The only 2 things I can think of to try when I get steadier wind is less pressure on the rail and a larger radius for the turn which I guess is the same thing....

    How long is the fin, how long is the wing, where is the wing located, what degree angle of attack , is the wing symmetrical ,so both sides with a foil ????

    A 5.5 then smaller seems large on the BIC.
