Becoming a hydrofoil expert

I got the book "Hydrofoils design build fly" by Ray Vellinga in the mail today.  It looks like a very good book.  I should be able to learn enough to make paravanes that work well.

There are human powered hydrofoils.  A human is about 1/8th Hp and with the machine is over 200 lbs.   My solar powered boat wants like 25 normal  to 100 lbs peak pull.  So this should be less than 1/16th Hp each, but I have 2 paravanes, so less than 1/8th Hp.  The electric motor I have is about 3.5 Hp.  The drag for the paravanes should be acceptable, if I get a good design.

The shape of those techniques is often small however consistent losses adopted by occasional big wins. However, over the long run|the lengthy term} these wins do not compensate for the losses incurred in between. Negative progression techniques contain increasing the scale of one's guess after they lose.
