    I have a longboard in the works.....first one I've made since 1995. This time I decided to make my own glass on fin. Layed up a panel this morning. 34 layers thick. Shaped it this afternoon. Came out absolutely perfect. Very fun little project. I may be making shortboard fins in the future. I can see how this could become addicting.

    By the way, any spots in the pictures are not in the fin. I doused the fin in water and took pictures quickly to capture the effect of what it will look like glossed on a board.

    You appear to be trolling for a critique of the red fin.

    so... the chord ratio is too low and the foil looks to have a huge flat area which drastically reduces performance.

    I can't tell without feeling it or seeing a cross section. Aesthetically, though, I think she's a beauty... especially on that yellow bottom.

    Finally got back to work on this project yesterday. Got everything sanded out. Ready for pinlines and gloss coat. I'll get some good pictures and post once its complete.

    PS. I can assure everyone that the fin is properly foiled.

    You did say that it's 'perfect'.

    Anyway the cross section can be seen at the base, and the thickness and chord ratio can be estimated via the same method and the number of layers used.

    Had I taken a picture of the fin dry you would have clearly seen the foiling in the layers of cloth.......I wet it with soapy water so I could capture what it would look like glassed and glossed on a board.

    I posted all I've got for now. The board is glassed and sanded. I've got to do the pin lines and gloss coat. Then I will be taking pics. I'll wrap this board up sometime in the next week.

    well if anyone would know about making something with reduced performance, it'd be you Roy!!! lol. I think the fin looks well within suitable shape for a longboard/funboard. its not like that board is ment to be slashing and gashing up and down the face. Just a straight shooter, down the line runner like your boards, Roy.
