Many thanks gentlemen that's very helpful. Cheers TT

What treatment or coating (if any) should be applied to the inside of a steel hull before applying sprayed foam (PUR or PIR) insulation? Thanks

Although on the Mississippi/Missouri, and with vastly different boats to what you propose, there's some great detail in this terrific historic resource on the techniques and difficulties of taking canoes up a big river. Lewis and Clark did carry sails on some of the variety of boats they used...

Current records for pump foiling on flat water seem to be in the ball park of 25km: The Official Foiling Book of Records - Foil Pro https://foilpro.co.nz/world-foiling-records/

I can't imagine that the wings used by wing foilers are very efficient - that big fat tube as leading edge and then a single skin - is there a reason why a double skin couldn't be used, with membrane ribs and inflate the whole wing to produce a much better wing section?

An interesting project here, with respect to this discussion - using the sailrocket approach of the reversed foil anchoring the rig in the water:

A friend of mine, a Scottish fisherman, in a fairly remote village, has just converted his boat to electric, with PV on the boat. Interesting that it is a bottom up project, not top down. The biggest difficulty has been certification. The film , made by another villager, is not released yet, but...
