Seems like a good idea, but I'd be worried to use it to extend a short mast, especially when using a big foil, due to the extra torque/force from the extended length. The GoFoil small mast is thinner than the longer masts and might not be able to withstand the extra force when turning or being pummeled in surf.

An extra piece adding complexity, potential movement points and potential failure points. Sorry, just giving one person's opinion.

I am impressed!

Will it work with any brand?

Can you put a diagram with angles and dimensions on the web site? That we can measure our gear and know it will fit.

Will the sleeve fit a Deep Tuttle mast head? How deep is the slot? My Gofoil heads are 60mm deep. My Deep Tuttle heads are 68mm.

I am assuming the top of the sleeve will fit into a Deep Tuttle slot with the taper holding it in place. There will be a bit of a gap at the top, but that is normal and handled by having long enough screws. Is this correct in terms of the sleeve? How deep is the head of the sleeve?

Can you tell us anything about the anodizing? Our experience is that not all anodizing is the same. Some anodizing stays on. Others scrapes off. What kind of anodizing process do you use?

Wow nice bit of work there well done but what's with the bolts sticking out of you base plate , don't you use T nuts .

Hi Piros! This is actually a hangover from when I used to use different shims under my adaptor plate to play with foil angles! they are just super strong... but you are right - i'll change 'em

Thanks Ausiet! We designed it around the gofoil tuttle which is 60mm deep with bolt holes 105mm from centre to centre. The male end of the FOILSLEEVE is an exact copy of the gofoil male end, and 0.5mm thinner than the universal tuttle box width. Many foils are built to this universal dimensions, but please check your tuttle box bolt holes are 105mm from centre to centre!

FOILSLEEVE is made from T6 6061 aluminium billet and anodised to international marine grade at 25 microns.
