While I'm yet only using my new Sabfoil Leviathan 831550 hydrofoil kit for SUP, I tried mounting the foil on my two years old Sabfoil T35 kitefoil board. Trying dock/rock-start any cloudy day now, cooler for full suit/armor and less spectators.
Sabfoil has replaced the T35 with the very similar model B14. Both are 108cm long. They also have the B08 that is also clearly aimed at pumpfoil, but at 90cm it is not for me.
Pumping with a SUP I have measured the preferred stance to be exactly 90cm, from front of front foot footprint to back of rear foot footprint. Meaning, zero margin for jumping to the right spot. I'm 190cm with relatively long legs, smaller riders with narrower stance may of course think differently when choosing board. And who knows, if I ever advance in dock/rock-start, I might tend to have a narrower stance. Other riders have reported that you can pump the smaller Leviathans almost with same foot pressure, without the need to work so much pointing the board nose up and down. That makes narrower stance more likely I guess.
See board/foil relative sizes in the following pics and make up your mind about your first dock/rock-start board, given that you choose one of the big foils.
