Jack,
I can't help you with the registration, but Boat US has about the best boat  
insurance available, especially if you're purchasing a recycled from Sir  
Stanley. The amount a boat can be insured for is usually determined by Blue Book  
value. Since so few R22's are ever sold by dealers, they have little or no  
information to go by, so you can negotiate the value based on what you paid for  
it, including the trailer, motor and any other options. My 88 model is 
insured,  meaning boat, motor and trailer for $12,500. Try that with you local 
automobile  insurance agent and they'll balk at the value.
Congrats on getting such a superior boat. You are a lucky man.
 
Rummy
