Custom fin for a custom SUP
Description
About A Year Ago I Shaped A 12' Sup To Use As A Frame For A Hovercraft. I Decided To Go With A Different Frame That Doesnt Tip So Easily For My Hovercraft And Am Now Left With A 12' Sup. Being That I Love Sup'Ing And Was Already In The Market To Buy A Second Sup For My Wife, This Worked Out Perfectly. We Took It To A Lake This Weekend, And It Performed Great Accept That It Didn'T Have A Fin. So I Designed This Fin To Be Attached To A Board Without A Fin Box. I Am Going To Epoxy/Screw 1-2 Of These To My Sup And Will Report Back How It Works And How It Looks. I Plan To Run This Through My Acetone Vapor Chamber (For Added Strength), And Sand It Aggressively. I Believe That The Trailing Edge Should Be Sharper Than It Is In The Model. Will Have To See What It Looks Like After It Prints. I Am Not A Fluid Dynamics Engineer, Nor An Excellent Surfer/Sup'Er However I Think It Should Be Decent Which Was My Goal. I Didn'T Want To Take This To A Glass Shop And Have A Fin Box Installed, So If You Need A Fin And Dont Have A Fin Box This May Be For You! Some General Fin Basics: There Are Lots Of Fin Configurations. I Do Surf My Sup'S But I Also Have A Sup That Is Perfect For Surfing So I Probably Won'T Be Riding This Board All That Much In The Waves But May Occasionally. For That Reason I Am Using 1 Large Fine With No Cant. This Fin Is Not Really Well Suited For 2 Fin Or 3 Fin (Thruster) Setups Because The Fin Rides Perpendicular To The Board. Most Thrusters Use A Different Foil Design, Are Toed In, And Smaller Than The Center Fin, Which Makes This A Poor Choice If You Want A Thruster. If You Want A Stable Fin That Is Fast, And Good For Large Boards And Beginner Boards, This Should Be An Okay Design For You.
