Seriously though - can you post a picture of section you’ve got?
What section?
By the way agree completely with your above definitions,
A mast IS
"a tall UPRIGHT post, spar or other structure ON a ship or boat, in sailing vessels generally carrying a sail."

Mike Murphy came by our spot last weekend. He seemed to care more about not cashing out on this foil craze rather than what that thing is called :wink:

More fuel for the fire. Note the word mast, mat, is used no where.
As for MR MIKE MURPHY ( respect ) as far as my extensive hydrofoil history research goes he gave us our basic design.
If anyone has other info please share.
And yes to bad if if this is true that he was not able to patent, attack to protect , making the money he probably merits!

" their product as the Dynaflite Hydrofoil. The Hydrofoil consisted of two regular waterskis with two struts attached to each ski with a bi-wing design."

After getting blasted with water from the center of the skis, Mike came up with the idea to have Bob move the skis together so that the wash from the spray would be off to the sides of the ski. In addition, they changed the hydrofoil from a double strut to a single strut. This design eventually became a single ski with a single strut.

I see patent numbers on both ideas but when search find not.
Anyone know how to find these patents please?

As for the carbon layup schedule on my beloved snapped STRUT, as I did not make it I do not know.
Enough to say it was built by well known garage builder with tons of experience both in design and fabrication but clamped mold, not vac sack, high mod
carbon with correct epoxy and mixture of bibias and uni with foam core.

I would wager you could call it a "chassis" if he was paid what was,is most likely his due!
I would sure like to shake his hand and say bravo!
But it is and always will be correctly named a STRUT!

Yes I've head the same argument from language students...
"But my dictionary says it means this."
"But your dictionary was printed in 1890."

Well, again. Try to use a foil mast like the rest of us do - they don’t break like your strut from the prehistoric patent you attached.
Did you also used it with skis?
