That was an interesting exercise, and from a non-technical point of view I can only agree with it.
When we come to a cruising scow, though, one must wonder how often it is going to plane. The Raison Revolution 29 is 4570kg, which is a heck of a lot of weight for a 29 footer that is going to plane frequently! It's only 225kg lighter in listed displacement than my 40 year old 36 footer, which has sailed halfway across the world, and has a vastly higher ballast ratio so is unlikely to be lower in stability.
Looking at two boats a French mag compared the Revolution 29 against, we see that the Django 980 is longer, a ton lighter and carries a much bigger rig than the Revolution, so it must surely be faster overall. The RM 970 is significantly lighter than the Revolution and therefore probably faster although it has a smaller rig. And yet the RM 970 is rated under OSIRIS as having the same speed as the X332, Dehler 33 competition, Dehler 34 cruiser, Seascape 24 or J/92 - so for a 9.7m boat the RM isn't particularly fast. The Django is rated the same speed as the JPK 1010, Dehler 34 (2016) and XP 33. so again it's not particularly quick for a boat of its length or sail area.
If we assume that OSIRIS has its numbers correct, it's hard to see much evidence that the lighter "Open-influenced" racer/cruisers are particularly fast so one may well believe that the heavier Revolution is unlikely to plane often enough to make it particularly fast - and one still has to pay for those enormous sails.
There's a lot of publicity about the Revolutions and yet it seems impossible to find race results for them. I suspect that if they had done well, the publicity machine would have splashed the news around everywhere.
