Why the vents ?

[Billybob]

I've been asked this by friends, and often wondered myself.Why do Seacraft's have the vents on the hull. The only thing I can think of is that they were put into the mold in case an inboard was installed, and so everyone got them. Maybe someone here knows, I'm sure Mr. Potter does. Just curious.

Those vents increase the speed of the boat by 10 miles a hr. plus reduces the cost of gas my increasing the gpr by 40 %. Just kidding I also asked my self that question a few times until I removed the my gas tank and saw that all the vents lead to the gas tank area of the boat. They are used for ventilation of the gas tank and for as you figured out the i/o power plant. Personally I thought that it was a bit to much overkill kind a like the fins we saw on some on the 1970 cars. When I did my re build I filled in all four of them with glass and epoxy I didn’t think they did any good and they were a bit to retro for my taste.

They are for filling the hull with water in rough seas.

I built a T-top for a 23 last year That had the vents in backwards [img]images/icons/grin.gif[/img] . The boat was a brand new restoration from a guy on the other side of town. This was probably the 6th Seacraft I have done for him.

I have the vents. We fished this year in some pretty nasty stuff (4-6). When we got back to the dock we noticed both of the forward vents where ripped off the boat. The new ones are 5200 and screwed into the hull now. Does anyone know where we can get inverted vents for the back I need them to sit into the hull (flush) more? They seem to be the perfect height for floats to break them.

Thanks

Just my opinion and a swag but If you run a bilge blower(hope everyone does),you usually only run it before starting your engine ,when starting,and for idling after starting. Anyways, when running you get forced air ventilating your bilge (air exiting thru blower on one side and open vent on another)by design without a blower running. On older boats(built before 1980?) ,I believe blowers were not required or standard equipment at all and although not as necessary on outboards or i/o's , they are in fact very important on inboards because of all that electrical stuff located in the same bilge as fuel tanks. I love my vents.

Yes you definately need the vents. I am just getting tired of replacing them in the back. Also check the one side and make sure that it is actaully a working vet. Mine was solid behind the vent.

First thing I did when I restored my boat is fill in those goofy vents! Of course, my boat is an outboard, and they served no purpose.
