Attaching a foil to an old twinny?

Postby dragnfly » Fri Mar 16, 2018 11:19 am

Basic nooby question.

I have an old twin tip that I'm considering bolting a foil to.

Is there any reason why this wouldn't work/ shouldn't be done? It's 138 x 41

I've never ridden a foil.

Thanks

It is a bit difficult to learn to ride a TT hydrofoil as board is small.

Another issue could be, that it almost (or do) sinks, at least if a heavy alufoil.

Even if it does not sink, but almost, it can be difficult to spot on the watersurface.

Thirdly, it will most likely be too soft and flex, so not that good for hydrofoiling.

Yes it can work and has been done !

Would not recommend it though...

I have a friend who did it with an old wakeboard. It works but it took a lot of mcguyver fiddling and then you have the issue of strap and weight placement. It works ok now but he learned on a more conventional setup first.

Also to add to this. The board will probably fail in time because it is not designed to take the additional point loading and stress a foil provides. Also most
tt's dont have much nose rocker, So it will be a lot harder not to dig the nose in during touch downs

Think about bolting an additional plate or adding some more glass/carbon to the board. Test the assembly floats before going deep. heavy alloy foils will need some board buoyancy light carbon or home made wooden will not. You can add boyance to the board by putting a full length foam deck grip on.

Here's a pic of my foil bolted to my mutant.

That's not where I live! that's a little place called Yeppoon in Aus.

But I don't have it too bad either!

My mate did it and it works fine - I had a go on it.

You probably are better off on a larger board though when learning.

Forget about learning on TT. For the first steps will be better big board (for expl. 150x50) with a lot of volume 30-40 kg.
Can try TT when you'll learn ride in levitation .

I've done it to several boards.

Definitely not for learning, bolt to a skim or something bigger with more volume if you are a beginner.

Once you have foiling down then bolt it to a TT and put some foam grip on top, works awesome. As stated above, flex is bad so try and use a stiff board. Otherwise just get stainless bolts/nuts/washers and drill right through the board and bolt it on. As long as it doesn't have a foam core you are fine.
