Why are the screws angled into the deep tuttle?

Postby lovethepirk » Sun Jul 15, 2018 12:38 am

What is the reasoning that the deep tuttle has screws going into the tuttle at a 6.5 deg angle? Why not either make the top flat or just make the tuttle so that the screws come into the barrel nuts straight down?

I'm possibly going to make my own carbon fiber insert and I'm trying to engineer this thing and I am at a loss why it is the way it is. Thanks...

The Tuttle standard was originally for windsurfer fins and the angle of the top was to accommodate the typical slope on the back of windsurfer boards.

All Tuttle hydrofoils have small threaded barrel nuts (press fitted in) which can be rotated. In practice these can be rotated enough so that the screws work on flat boards (and are perpendicular to the base of the board).
