A question for those of you that have divided their anchor locker along the boat centerline. I am at the point of cutting out the floor of the shallow anchor locker to open that area into one big compartment. I plan to store 300 feet of 3/8 chain on the starboard side and 280′ of 12 strand with 20′ of chain on the port side. A dock neighbor wondered if that chain rode weight would cause the boat to list to starboard. A suggested alternative would be to mount the divider between the two rodes transversally port to starboard, so the weight of the all chain rode would be more evenly balanced across the beam.
I would appreciate the benefit of your experience with this.

Chain on the PORT side might offset the Coriolis effect in the northern
hemisphere… but you might have to reverse after your Neptune party….Pete

Hi Dan,
All funning aside, the major trim worry that comes from this would be
pitch, bow down. If you’ve already put that amount of rode up there then
you’ve already dealt with that.The rolling moment arm from the division of the rodes would be negligible.

Dan,
I reinvented Silverheels’ chain locker several years ago. If you can’t
find the info & photos of that project in this group’s archives, let me
know and I’ll email them. In particular I’d recommend making the divider
removable to permit access later. Certainly in my case a fixed divider
would’ve been a big mistake.I don’t believe carrying the bulk of the chain on one side of the locker
will cause the boat to list, being so close to the centerline. In fact,
although 75% of my 200′ of 3/8 is on the port side of the locker, my
boat lists slightly to starboard. Go figure.However, as Bob Fine forewarned, it is likely your boat will ride
permanently bow-down with over 300′ of 3/8″ chain (plus a pair of big
anchors) so far forward. My chain total, as I said, is only 200′ of 3/8
(150’+line and 50’+line, + 45 lb & 66 lb anchors) and it’s too much
weight up there for this moderate displacement boat. I know this because
she sits slightly bow down, even after stowing only light stuff in the
forepeak and leaving that forward water tank empty. I realize anchoring
conditions occasionally call for lots of chain, and I’m a big fan of
oversized ground tackle. Still, if I were doing it again I believe I’d
go with 5/16″ HT chain (in the same lengths). I’d also install a
horizontal windlass instead of the vertical I have, for easier handling
of the second anchor.If you feel you must carry 300’+ of 3/8″ chain, see if you can lead it
farther aft. For example, you could cut into the forward water tank.Let’s see, what else? Oh, seal the chain locker bottom so it no longer
drains into the bilges. (What was Pearson thinking?!) Then drill
overboard drain holes at the very bottom of the locker sides, port &
starboard, angling them down and aft from the inside. Presto, a
self-draining chain locker. Works great.Oh, splice 10′ of line to the inboard end of your all-chain rode, and
secure the bitter end inside the chain locker. If you ever have to slip
your anchor in an emergency, you’ll be glad that the end can be severed
with a knife.More if you want it.
