Wow, That looks like a fairly large shop, Nice to be inside for all that
type work.
Do they have any DIY shops up there now?

I did a dive job for Trident up there a few years ago, and remember
thinking some of those empty waterfront warehouse space's would be ideal
for overhaul/refit's. I doubt for the DIY you could get that type space
nowday's the way insurance, and DOE laws are now.
Prolly been slated for condo's anyway. UD
