Don't have any answers to any of your questions, but had to add my own M.E. story.
I was in the Bahama's in "88 for my honeymoon, strolling the docks at port lucia marina and stopped to admire a offshore boat docked there. It was a M.E., and I'd never heard of them before. It had a raised area on the deck similar to a bullet. There was moss growing on the hull and drives over an inch thick. Looked like it had been there for a long time, without moving. While we were inspecting it, looking it all over with lots of intrest, a Bahamian Police officer walked up and asked why I was interested in the boat. Told him all the above, and I wondered if the owner might be interested in selling it as he was not using it. That made the officer very interested. Long story short: It was a confiscated drug runner's boat, and the office thought I was involved. Visions of rotting in a bahama jail popped in my head. I must have looked like a scared little kid, cause the officer told me to just leave the boat alone, and I could not get out of there fast enough. It looked like a nice boat, and I'm glad you started this thread.
