Handbook, performance data from White's RM, and Noble Cab (similar to
River Belle), and whatever I could glean from Atkin's writings.
The spreadsheet is a bit rough, and is really useless without Gerr's
book nearby. But I would be happy to share it.
BTW - Gerr designed the power for Noble Cab, with (as I recall) 100HP
Yanmar, 17x17 5 bladed prop (the prop cost more than any boat I have
owned). I understand he expressed some scepticism as to whether it
would perform as well as Atkins claimed. She met all expectations, and
I suspect might have done better if Gerr had pushed her.
