Any yacht brokers hang out here?

Are there any yacht brokers that hang out in this group? I'm going to be 
preparing a 41' wooden sloop for sale one of these days, and I have some 
questions about certain upgrades that I'm thinking about doing. I'm 
wondering if I can get some informed opinions about whether the cost of
the 
upgrades would pay off, either in terms of making the boat more attractive

for sale or getting me a better price.

Thanks,
Tom Dacon
