In terms of breaking strength, BBB or HT in 5/16 are plenty strong enough for Jason's boat and displacement. .....
HT in the 5/16 size is stronger and lighter and more expensive and WILL work in many BBB capstans but IS slightly different and MAY not be compatible with a specific capstan. BOTH HT 5/16 and BBB 5/16 are more than strong enough for your boat and storm loads.
I'd like to recommend that you three read up on chain a bit more. Talking about different types of chain being lighter or heavier, when the wire is the same diameter, is ridiculous. HT is not 30% lighter than BBB in the same wire size, but it is twice as strong.

Acco G4 HT 5/16" chain weighs 116 lbs. per 100'. Acco BBB 5/16" chain weighs 118 lbs. per 100'. The difference is 1.73%. However, the 5/16" G4 HT has a SWL of 3900 lbs, and the 5/16" BBB has a SWL of 1950 lbs.

Given that the weight of the chain is essentially the same... why would you want to get chain that is only half as strong?
All chain, that is the same size wire is relatively close to each other in weight...

Now, if you were forced to use 1/4" chain for weight considerations, 1/4" G4 HT weighs 79 lbs. per 100' and is still stronger than the 5/16" BBB chain, with a SWL of 2600 lbs. This is a significantly lighter chain, since it is only 67% of the weight of the 5/16" BBB. I think this is the part that Cam has confused... since G4 HT chain is generally as strong as the next size up in BBB chain. 1/4" G4 HT is a bit stronger the 5/16" BBB, but weighs 33% less than the BBB. 5/16" G4 is stronger than 3/8" BBB, yet weighs only 69% of the weight of the 3/8" BBB.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
