Everybody suggests anchor locker drain but surely its the drain for the chain locker ? Is that not where the anchor chain stows ?
If so the fact that water will tend to enter will mean that the chain in the bottom will always have water swilling around it and rust quickly
Id make a false loose bottom to fit a few inches above the drain hole to keep the chain out of the water.
VicS,
please for the sake of all that's holy don't tell me you use all chain on a Sea Wych ?!
The anchor rode I use has 4 metres of 1/4" chain then 30 metres of 14mm nylon 3 strand; when recovering the anchor I try to flake down the warp ready for deploying next time.
I do see Bens' pic of the hole from the outside shows a rust type stain; if that area isn't used for carrying the anchor I'd urgently suggest a look at the forestay, pulpit stemhead & cleat fastenings, but especially the forestay, no joking !
