It is always surprising for me how detailed technical data is hard to come by on some of the official builders website, and catalogues. With some brands a buyer looking for some detailed information has to ask a salesman, and be lucky if this can answer to his question directly without a wait. May be some builders still think that the emotion perceived by the looks of the boat can actually make buyers ignore technical details. I am sure for some it is like this, but for the many how is that. I am sure many who when coming to the final choice between two crafts, open the specifications and compare much as possible.
Some builders even don't state any engine makes and will tell maximum horsepower giving a certain speed. Another lacking detail is always the Vee dead rise of some boats. You go to a show, the boat in question has a covered hull, and the salesman will tell you it is a deep Vee. You take the cover off and then you find a fifteen degrees dead rise aft. Deep Vee is twenty degrees deadrise aft and more to fore. Under this technically speaking it is called a medium Vee.
Should there not be an implemented standard for specification globally.
A builder which makes good technical specification is the Ferretti Group, still needing some minor improvements but of the major European brands it gives good over all information. Some of the Americans take the praise for also delivering in some case the full first test report on performance, and also giving the hull dead rise aft.
