That is true IF you mount them straight up and down but if you face them

the passing flow will create a venturi effect and they act as bailers.

Fast moving water on the outside and still water on the inside makes
lots of negative pressure.

Unless the drains are always above water, even when pitching hard in
heavy going, I'd make the holes a lot smaller than 3/4". With a hole
that big you'll be taking in a lot of water on the down stroke and
then draining it back out on the up. The dynamics are such that the
water is more likely to go in than out, so you end up with a lot of
weight in the worst possible place. Check valves are a tempting
solution, but will likely stop working when chain goo gets in them.

Swee****er (Swan 57) had 3/8" holes, I think.

The good news is that it's much easier to put a restrictor in than to
bore them out....

My chain locker is self draining. I was about to bore holes in the
corners for some 3/4" through hulls and then screw clam shells on the
outside when I ran across some really neat looking hooded drains on
ebay. These things are heavy 2" wide cast and polished stainless
clamshells that are threaded on 3/4" Maralon through hulls. No
exposed screws. Missed bidding on them but asked the seller Julia
Farichild, if she had any more. It took a couple of weeks to get
them but they are just what I needed and only $10 each. That is less
than through hulls and those cheap stamped metal clamshells.

Turns out her brother makes them for a couple of production builders
and never tried to sell them outside so she is feeling out the after
market on eBay. To spare here from the spammers, if you are
interested email me and I will send you here address.

No connection, just a real neat product found by serendipity.



Yeap,

That's the way most of us that are too stupid to remember to put the
plug in the boat, get all the water out when fishing. Just start moving
and it will suck all the water out, then put the plug in.
