NVIC 7-95. This is the USCG vessel inspection document. Which states that
stainless screws are NOT approved for underwater use. This document is used
by the fishing vessel safety system.
The circumstances under which they are approved are roughly as follows. All
the conditions must be met.
1. Type 304 or 316 stainless.
2. Not installed in wet wood. (underwater?, you bet)
3. Not in contact with any metal less noble, which would tend to cause the
hole to enlarge.
I have queries into the Passenger Vessel People, but I am quite sure that
they cannot be used on any "T" boat inspected to carry passengers.
Regards,
Mike
