Feel I must stress that things can get a little damp around (& sometimes in) boats, so please take good care of your instruments!!!

I lived on a (holey) boat on the Thames back in the mid 80's for a year. I bought it for £800 & sold it for £1 for salvage after it finally sank for good (never actually got the £1 but it stopped me from being the legal owner & liable...)

Good luck with moorings!!
