If they are a member of our association, though I can't speak for those that are not, any boat that is sold in Canada or the U.S. has to go through a rigorous certification program, which goes above and beyond the U.S. Coast Guard standards and even some of TP1332 construction standards for Canada. For example, on the styrofoam in particular, everything is in a sealed airtight compartment, so there is no way for that to leach out. It's completely sealed. The engines are completely sealed and very well done.
I would be more than happy to provide some of the more technical engineering aspects of what we're looking at when we're certifying a boat. We could also look at the provisions of the Transport Canada Construction Standards, which must be met to be compliant for a boat to be used here.
