[QUOTE=BigLew;212233]I guess Istarted a fire storm

You didn't start a fire storm at all I'm new to SC, been a long time mako guy just stepped into my dream machine. ;) and want to be sure I don't kill anyone or my boat! I appreciate all this knowledge

No vents = Death & eminent destruction, vents = bliss & immortal SeaCrafting, lol. For myself I understand why they are there I also think they can sometimes look out of place and more dated than classic. One person's choice isn't another's, to each their own.

Capt Chuck,
I have a 1978 23' that is in need of new vents. Where did you get yours?

Thanks,
Mike

There are plenty of 20 seacrafts with below deck tanks and no vents. Were the 20s originally built having the vents?

Let the imagineering commence. I would have to take some numbers with a tape and think for a while. Boat owners warehouse has a few designs that could be improved quite a bit. I`m thinking sleek, subtle, and low profile. Match the gelcoat? What are your plans for the old spray rails?

Cheers and keep asking,
GFS

mine has vents

Of all the 20s on the pictures portion of this site, I don't think any have vents. Whats the big difference between the 20s and 23s???

Interesting. I never noticed that the Potter era 20s don't have vents. My 20 is a Seacraft Industries Hull, and like Mikem's it has vents.

Mine has vents, big clamshell type made from Marinium on aft gunnel; stbd side faces forward, port side faces aft, with hoses leading down into the bilge. The later 20's had plastic vents in hull just forward of transom, similar to the 23's. The later I/O models, like Strick's 20' Sceptre had vents just aft of the engine box.

Hey all listen Im not trying to be difficult or stubburn here just want as much info as possible thx for the prior posts. I appreciate it.
The queation waa posed why dont 20s have them???? Again my wheels start, i call some of my marine guys all with different answers.
Is it just as simple as obviously SeaCraft made the Inboard model on the 23, could it be that they just kept the hull design for all 23s? So each hull is the same? I'm just throwing it out there, as a long time boater (well I'm only 32yo but been boating my whole life) I completely understand the air vents on an inboard, dangerous situation there, I have seen that explosion as I'm sure a good amount know ir heard of a boat blowing apart bc the blowers weren't put on.
But the outboard is set back 3ft (with bracket) so fuel line is out in the open air for sure. As far as the tank and fumes,...I just don't see why it's different from any other boat? Whether Foamed tank or not, idk? Just seems like u would see it more on other boats wouldn't u? I mean a fuel tank under he console is not irregular, the hook up and sender are located there and I assume fuel fumes would be the same issue on every similar hull? No? Again even the 20? Why wouldn't hat be an issue in that model?
Are there any cases of SeaCrafts blowing up for this reason? I don't know...... im I asking...?? i cAn do a search. I'm not talking about other model boats, again I have seen that happen. Im Talking SeaCraft 23s and something ill happened from lack of vents. As opposed to some drunk dude who ignited a flare while filling gas lmao!!! Again I'm just curious it's and interesting topic and I want to be sure I want/need to do this before I redo the precious owners fill job.
