What is this big concern with water through the dodger? We are talking about a narrow slot at the bottom of the dodger that allows lines to pass through. The only way you are going to have significant water coming through that opening is if you are punching your bow into waves and have green waves washing the length of your decks! I am guessing if you are sailing in conditions like that you are gonna get wet anyway! And if you have to go up to the mast to make adjustments? You are going to get REALLY wet! Sailing is a water sport!
Power winches? Carpet? Enclosed cockpits? Might as well just buy a power boat!
