A very quick test on a twin cam 9.0, so ignore all the info. Was actually on the H-91 foil board without the foil.

After testing I rigged the 5.3 Vogue and went cruising on the foil. So nice and easy to go upwind and downwind. Sailed about 3 km upwind, around the top of town, along the north shore a bit, then crusied back again, waving to the ferry as it passed by. Top speed on the foil was just short of 20kts, but like I said I was just cruising.
