I just finished a relatively unpolished but chock-full o' wisdom book called "The Warm Dry Boat" http://www.nauticalmind.com/Warm-Dry...-pr-66240.html
Good, brisk fun, and it's given me several ideas for dorades, etc.
Even though we'll be mostly in the tropics, we may overwinter in Britain, New Zealand and Canada's East Coast. This means we need a diesel heater (bulkhead or free standing will depend on other factors) for the main saloon, in which we can all sleep on frosty nights. Due to the "wetness" of propane, I want to use diesel pot ring-style heating. Must I run the "chimney" straight up through the deck to a Charley Noble, or is it feasible to run it to a fixed portlight, drill a sufficiently large and insulated gasket and have it going out that way?
I ask because I wish to avoid sooting the sails, crowding the deck, obscuring my view from the pilothouse further, and avoiding the dreaded "down draft" that can really make diesel heat unpleasant when it has to smoke against a sail-created head current.
