I want to put heaters in my Pearson 33 and Tartan 34 to extend the season away from the dock. They would mostly be used at
anchor, but possibly underway some protection. There are a lot of different people using the boats. I have an alcohol
stove in one and a CNG in the other, so no propane tanks. Engines are diesel. The solid
fuel heaters seem like a possibility. Are they dangerous?
