Skimming through old design books,pre 1950, i note that there seems to be a lot of arc bottom plywood construction runabouts and cruisers,some up to around 24 ft. I dont recall seeing many new designs that are arc bottomed, and wonder why the V appears to be more widely used in preference?
Any clear advantages of one over the other in terms of performance or construction? I would have thought an arc bottom would be more liable to roll at rest than a V hull,but may have less wetted area for the same displacement when planing. I recall reading that an arc bottom can "skid" in hard turns,more so than a V, unless fitted with skegs and rails? Im generally interested in the use of arc bottom in outboard powered craft rather than under sail.
It appears the only downside of the arc bottom would be the rather flat entry,which could cause some pounding,and that in itself may be a reason why the V seems to be more in use, though i dont see why a transition from arc to a V forward could not be achieved?
Comments from all and especially those with experience of both welcome. Cheers.
