Modified V shape (warped Plane) HUll = variable dearise combines sharp v at front (bow) ensd of boat to punch through water and a shallower V at the stern to facilitate planing and give a bit of comfort. Fast-planing powerboat hulls often combine a deep V at the bow and a shallower v at the back end (stern)
.A deep-V or constant-dead-rise powerboat carries the steep deadrise of its entry from the hull to the transom. A constant deadrise hull needs more whoomph to plane and is not as fast in calm water as a modified V, . It's not all bad news as it can keep flying through seas that require variable deadrise to slow down. They are faster and hold their course at speed better but turning can be a little more tricky (the fat arse of a modifies V gives a more stabilised turn). Deep-V powerboats are tippy at slow speeds but acquire stability when planing. They hold course extremely well but may turn with difficulty, and they have a tendency towards l chine-walking.
My comments about the dash being a pig in the rough, were not to do with srability it was to do with the high bow and where the water goes. which is directly in your face, rhis can be very debiltating after a while.
Maybe Dirk or Adam can explain this a little better, but the answer is you boat will be a lot more dependable in the rough than say an Avon Adventurer which has a variable deadrise..
I only know this stuff from converstions I've had with Johnny Fuller and Neil Holmes So If ADAM Y, Delta Rich, Dirk Digler or even Willbrooksy can add any other info it will probably be more erudite.
I had a quick snigger at Hightowers CAD design comment. wasn't the last rib manufacturer on here claiming CAD design a splasher?
