tunnel fins in bellyboard?

Unread post by asier esnal » Fri Mar 01, 2019 5:11 am

I've been looking in the forum but I have not found too much information or debate about these keels just this interview
https://mypaipoboards.org/interviews/Jo ... tml#Note_1
https://surfing-waves.com/forum/viewtop ... 2&start=20
http://waveslide.blogspot.com/2012/10/ur-simmons.html

the first information I found is from 1964

Could it be a good way to control takeoffs on windy days?
I have seen in square shape and round shape. my head burns, I do not want to do a hydrofoil, I just do not fly so much


es

he estado mirando en el foro pero no he encontrado demasiada información o debate sobre estas quillas solo esta entrevista

podría ser una buena forma para controlar los despegues en días de mucho viento?

This would be an easy way to make the keels, 5mm aluminum sheet folded and screwed to the wood

Don't worry about going crazy. You will be in good company.

Posted in 2003 I think...photos are deck-down, looking at the underside of the boards

Modified Tubes Paipo: That has been the basis of my idea, the other photos I did not know.
  I saw the tubes on the sides and I thought a version of that would be for my paipo, it is the great thing of this community to be able to learn from others and be able to contribute

Both John Mellor and Surffoils post on Swaylocks, Surffoils sometimes drops by here. He is working on fibreglass flippers, at present.

No tube fins, but wave face contact thoughts:
