Deck vent - 02

I decided to join in the competition, here are a few notes i decided to follow - - easy to manufacture, since the system has to hold up for years and be cheap to manufacture(considering the total production run will probablyt stay under 500) - alternative materials - marine grade rubber seals and 5754-H11 saltwater proof aluminium. Very strong, very good to weld and work with generally - no "weak" parts - all of the sections were designed to be robust and very easy to fix - almost all parts are separatable and easily changed if the situation needs it. - feedback and renders appreciated(my quadro decided to shorch itself during the weekend) Thanks :)
