what is this?

Post by ford351c594 »

So I have been meaning to ask this for awhile now but never took any pictures till today. A through hull below the water line coming up in the back of the aft floor?

Looks like a great way to sink the boat...........

Is this the 28, right?
If you rotate by180dg this rubber tube, does it go meet the throughull?
If yes, then this is a floor scupper, and as you're saying it's a great way to create problems ...

Did this boat have a gen set at one time? Could be an old exhust port for one.

Unless you have a reason for it to be there, I would cap that ducker off until you can remove it and glass the hole.

Normally one would expect overboard thruhulls (sinks, showers, bilge pump, A/C, engine exhausts etc) to be as far up the hull as possible so as to minimize the possibility of them being a conduit for water ingress... The thing is that there are various reasons to have them as close to the water line as possible... For example:

1) Hull streaking... All such thruhulls will eventually cause streaks on the hull... These streaks will be caused by contaminants in the water... By placing the thruhulls on (or close to) the waterline this problem is eliminated...

2) Noise... You'd be amazed how loud even small sounds are when everything around you is very quiet (think some anchorage off an island)... By placing the thruhulls on (or close to) the waterline this problem is eliminated...

Now, to prevent water ingress the hose on the inside of the hull will have a slope downwards with the down bend as high as possible above the waterline...

yes. that rubber tube was connected to the through hull.

The top has been sealed by a one of those screw in round deck inspection plates.....

but I just don't like it. so it has to go while everything else is apart.

If you're not using it and never plan on using it removing the thruhull and fiberglassing the hole is the way to go... If you think you might want to use in the future (e.g. to add a generator) you might want to consider putting a seacock on it...

Just remove the hose
And put a threaded cap on it
Use some anti seize on it so you can remove cap in the future

If you do end up just capping the thruhull make sure you use a bronze cap (as opposed to a brass cap)!...

It may have been a live well drain.
