Noticed some foil brands have an adapter to screw on the tail to lengthen the fuselage, or stabiliser.
Anyone tried to make one for an axis fuselage rather than buying a whole new fuselage. Maybe possible to machine one from a bit of round aluminium tubing. Angles would have to be machined accurately. Probably only need 100 to 200mm.

Maybe a bit of bagpipe chanter ? 
Hey dartboy do I know you.?
Shape would be good but need solid aluminium, not Polypinkle or African black wood with a hole thru the middle. But I do know some bagpipe chanter makers.
There's a Facebook group called "board and hydrofoil building". I saw someone who made an aluminum plate (something like 1cm thick) with holes in the front to connect to the fuse and in the back a couple for the stab. I think he windfoils with SAB and seemed to be quite halpy.
This is a piece of a sailboat jib track, so the alloy is not corroding in salt water. Only used it a couple of times, then got the longer fuse from Naish, which lengthens both the front and the back.
Similar vein - anyone ever considered machining mounting holes in an Axis fuse to attach a tail closer to the mast?
(would certainly create a weak point in the mast, but seems not to be impossible with a decent mill)
Why go longer? Longer means your carving turn radius becomes much wider. Maybe consider getting a better stabiliser foil. And/or a more pitch stable front foil. Kiters routinely do 30 or 40 knots with short fuselages. Look at this bloke, Arthur Mathieu, who in March 2021 did a run at 45.5 kts (85 km/h or 23.4m in 1s) on the Mikeslab foil kit shown in the image:
