Hydrofoil is can be defined to be a one piece construction with different names for area. Like a house, it has rooms, bathrooms, kitchen, etc.

Hydrofoil defined as follows:

Strut- hydrofoil long shaft
Fuselage-the main body of an aircraft where the wings attach
Mounting plate (area) that mounts to board
Wings
screws, mounting wings to fuselage
screws, mounting strut to board

[quote="C A R A F I N O 2014"] Hydrofoil is & can be defined to be a one piece construction with different names for area. Like a house, it has rooms, bathrooms, kitchen, etc.

Hydrofoil defined as follows:

Strut- hydrofoil long shaft
Fuselage-the main body of an aircraft where the wings attach
Mounting plate (area) that mounts to board
Wings
screws/hardware, mounting wings to fuselage
screws/hardware, mounting strut to board/boat

ALSO; mast refers to anything above your head, like a flag pole, sail boat mast, etc. so this define is incorrect.

Keel refers to anything below the hull, so not accurate in this definition. As a keel does not have wings attach to it. It traditionally and accurately has a lead weight to provide balance to a ship for stability from/when heeling.

The proper definition for a hydrofoil is a strut. It may be helpful to reference a maritime dictionary as all our definitions are in nautical language and aeronautical.

hydrofoil |ˈhīdrəˌfoil|
noun
a boat whose hull is fitted underneath with shaped vanes (foils) that lift the hull clear of the water to increase the boat's speed.
hydrofoil

ORIGIN 1920s: from hydro- [relating to water]

Mast or Keel is what I've heard most, also manufacturers, use.
Mast is a bit confusing, i admit...

I went through the topic I got some findings.
Why do we not use a sailing vocabulary? Instead we use aviation one.
I thought foilboarding is about sailing seas rather than flying skies ;)
Check it out:
A fuselage is a main body of a plane.
A main body of a vessel is a hull.
Have you ever seen a sailing unit having a mast under water? Actually I've had - once they were sinking.
Whatever appendage of sailing unit got it is called a fin or a keel.
A keel of vessel from a structural point of view is is a beam around which the hull of a ship is built.
A fin is a thin component or appendage attached to a larger body or structure.

On Polish forum I created a topic with FAQ and proposed to Poles to use maritime expressions. Check out Question No.4:
http://www.foilforum.pl/viewtopic.php?f=2&t=83

I've been trying to convince Poles to use:
- a fin (our masts, struts (building roofs?), keels, T-bars)
- a keel (our fusalage) ,
- wings

And I think not too many buys it.
Most of users talks about planes, hydroplanes, masts.
Should I give up with idea to understand it as a sailor?

And as "Strut" hasnt been used by any of the new manufactures (and will certainly not be used here, because it seems so wrong)

I beg your pardon, I have and will continue to call it a strut because that is what it is, period!
Read carefully all definitions anywhere and ask your self how can you call it anything else?
By the way our sport was named "flysurf" in the beginning, also incorrect!
And it is also not kite surfing unless you are in waves.
Kite boarding is what we do when not in waves.

I beg you pardon :wink: Why not a fin?
Most sailors, except "kiteboarders", would call it a fin.
A strut? It might be used in architecture, constructions, automobiles, avation, human anatomy.
To make it even worse we have struts in the kites. Do they look and work like a strut underneath a board?

A fin - cannot be mistaken even by any non-sailor. This word is just reserved for maritime environment.

BTW. To make it more complicated Moses used to call it a "drift"...

That is why!
Do you read any mention of structral support any where concerning a "fin"?
Talk about confusion....." fin" can be easy to confused with "wing" because that also what it is.
To be fair "fin Keel" is not bad, but once again, read what a strut does, it`s function and definition as far as we are concerned is much more accurate.
Again from wiki,
strut
"A strut is a structural component designed to resist longitudinal compression."

hydrofoil http://en.wikipedia.org/wiki/Hydrofoil
"Description
The hydrofoil usually consists of a wing-like structure mounted on struts below the hull"
Exactly what it does on a KBHF!
Looks like the moth guys call it a strut as well.

Fuselage comes from spindle-shaped, whether in the air or in the water. And I find nothing wrong with calling the foils "wings", cause that's exactly what they are, submerged wings.

I agree with you Revhed, having looked "back" at the terms :thumb:

The difficult thing is, in our native language, "Mast" is the same word and easy to understand, whereas "Strut" is a thing many dont know about or uses, so it wont work well around here :roll:
That should not influence what the right english term is of course.

As "Strut" is the correct term, and used for the exact same in aviation, supporting the main bodies and having a low drag profile.

The vertical stabilizer could be called a "Rudder", as some hydrofoils are using these, others use a high fuselage instead, and others use swept rear wings (which has the exact same function).
It could also be called a "Fin", but this could lead to confusion as some might think the strut is the fin ?


I find that using terms from aviation makes perfect sense, as they are used in the very same way, so most will recognize the terms immediately :D

Board
Strut
Fuselage
Front wing
Rear wing
Rudder (if present)
