Someone actually did it and came up with results that made Calder make the opening statement.
It would seem Calder is citing the very good report done by Norwegian O Gulbrandsen in 2012. The report points to bigger props turning slower, increasing the gear ratio and derating the engine by the use of lower RPM fuel stops to prevent damage.
The report is well worth reading and spends much time on hull design and saving fuel by easing back on the throttles. The report also cites the need to install smaller engines to best take advantage of slower speeds. Way to go Coot.
Now if only I were doing a new build and could do it perfect, kinda like Steve Dashew has already done in his FPBs. Calder and Dashew are two very smart cookies, with Dashew putting his money on the line.
