I came across this picture the other day. It illustrates that while a designer can sweat over formulae concerning lift and drag, all his hard work can come to nought if the boat isn’t trimmed properly.
Trim is about distributing weight around the centre of buoyancy. But if the client—who is always right—takes the choice seat with backrest then the skipper has his work cut out for him. This one has sent the crew up to the bows and told him to act heavy, the crew’s up there looking rather unsteady and wishing he’d had that second portion of paella at lunchtime.
Of the 3 passengers one is barely containing his mirth, the other’s rummaging for his camera while the third, unaware of how he’s affecting the trim and worrying the skipper, is wondering what the skinny guy on the bows is doing. The skipper, knowing that the boat is only staying afloat due to its forward movement, must be opening the throttle and hoping that he can power the boat out of its hole and on to the plane.
