My $0.02:Use the coffin, and put storage under it too - like the newer YellowFins. Can't find any pics, but they basically put the coffin on hinges so the bottom of the coffin serves as a lid for storage underneath. Make sense?
I know many on here close there transoms in fully and run full brackets but up here on lake Erie that is not very popular and normally makes the boat porpous alot in the chop we have here...most regret doing it.
