Rperret-

My question is this... what are the bolts in the keel made of??? If they're 304 stainless, you'd probably be better off getting the backing plates, washers and nuts in 304 to prevent any galvanic corrosion issues between two different grades of stainless steel.

316L is a better material, since it is more corrosion resistant and doesn't suffer from the chloride stress cracking that 304 is subject to having in a chloride ion rich environment, like salt water or chlorinated pool water. However, 304 is about 15% stronger than 316 IIRC.

Monel would be great, but if the bolts are stainless, there will be galvanic corrosion issues whenever the bilge is wet.

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.
