Given that this is not just your boat we are talking about I think I should have some input.
Personally I'd go for one of those Dickinson things, smoke stack or no smoke stack. Diesel or Kerosene, even LPG is an option. Newport is the model we would instal but maybe for PNW you might need something a bit beefier.
They do still make a solid fuel heater but the problem with that has to be fuel stowage and don't try and tell me that a solid fuel heater is not going to be messy.
Thing I like about the Dickinsons is that you do see a flickering flame. That has to be nice.
