During the Moesly era, Merc did extensive comparison testing at Lake X of VDH hulls and conventional deep V's with the same weight and HP, and they concluded that the VDH was about 10% faster, so your boat might be about 10% faster that that Angler with the same power if weight is similar.
PowerBoat Reports did a great comparison test of all the 150 HP motors back in June 2006, so I dug out my copy and have posted the last 2 pages below which contained all the test results. I summarized all the data in a plot vs. RPM. All motors were mounted on identical Angler 204FX 2200 lb, 8'x20'4" hulls. The only gripe I have with the test is that ALL tests were done with the motors trimmed FULL DOWN! I"m sure they would have all picked up more speed if the motors had been trimmed out as far as possible! They did that just to make things equal because they didn't have trim gages on every motor. The tests would have been more meaningful if they had tested each motor at the optimum trim for the particular prop it was running, but I'm sure that would have taken longer, and those guys clearly weren't operating to the same aerospace performance test standards I was used to!
