As you indicated, your boat is wide & heavy - for the purposes of calculating
anchor loadings, about equivalent to a more moderate 35 - 40 footer.
Assuming a (storm)
anchor load of about 2,400Lbs, your 5/16" ‘BBB’ chain is undersized (WLL of 1,900 #).
I would recommend using 1/4" High Test (G4) chain,rated 2600# WLL (or 5/16" HT @ 3,900#), which is roughly equivalent to 3/8” ‘BBB’ (rated @ 2,650#)
The 1/4" H.T. will weigh only about 40% as much as the 3/8" BBB, and will take less space (both at a premium on a 32'').
The H.T. chain would be an appropriate match for a pair of lightweight fluke
anchors, such as the FX-37 “Fortress”, which weighs only 21# (or FX-55 @ 31#), or a 40 - 55# “Danforth” style (excellent in Bahamian sand bottoms). A 35# (or 44#)
Delta, or 44# Bruce, or your 44#
CQR would all make good alternative “companion” (backup)
anchors.
FWIW,
