Building Out a new Setup

[RobertAB]

So the past boat owner bought some nockoff chain, it doesn't fit the windlass gypsy and jams horribly. We tried getting a new gypsy but the chain has inconsistent sizing and still jams on either burrs on the links or extra fat link welds.

I think rather than fighting it, we're just going to get new chain. The original gypsy is 5/16th which I think is undersized for the boat, so the thought is new everything. We're planning on heading to Mexico soon on the HaHa, then we're not sure beyond; I'd much rather have what I needed to do South Pacific if we so desire.

This is the current plan:
400' 3/8 G4 Grade 43 400' main chain with Rocna 25
100' 3/8 G4 to a Danforth 40 secondary
50' 3/8 G4 to a new FX-37 for kedge/stern

The boat is a heavy Maple Leaf 48. We have 500G fuel, 400G water plus all our curising stuff. I'm guessing we're near 40k lbs...

I worry our current Rocna is undersized and that we should maybe upgrade to a larger Spade/Mantus and replace the Danforth with an FX-55. Thoughts?

If I'm buying a new gypsy anyways, is that the correct chain choice?

If getting a new chain wouldn't be much of an hassle. Then I'd say you go for it

A good starting point, for some indirectly relevant general information:

A 50 Ft LOA [13' Beam] sailboat requires a storm anchor suitable for 3200# design load.

I agree that your proposed anchors may be undersized.

I would buy a heavier Rocna/Mantus/Spade and get a heavier chain if you can carry it.
