RE: TBT Ban
Actually there is NO restriction on any boat entering US waters with a TBT painted bottom. The restriction is on work done HERE in the USA where
"use is prohibited on non-aluminum hulls and vessels
less than 82 feet in length"
TBT is still allowed for use on props and shafts and for larger vessels including the US Navy and ANY aluminum hulled vessel. If you are a US skipper of a US boat and get your boat painted down island with TBT, there is no problem bringing it back to US waters.
OK...so that is the legal status. TBT seems to be pretty bad stuff for the marine environment and recreational boats have other alternatives that are effective....now if they could just be as concerned about the big ships. Kinda feels a bit like the marine head discharge rules." Let's get the little guys so we can make headlines" while letting the big guys keep dumping.
