I know it is an old thread, but came upon it as I was searching to re-tile the front of my Simpson-Lawrence fireplace on my 1966 Ted
Hood Auxiliary
Racing Sloop (Hood 43). There are certainly newer technologies, but old still works really well.
I started using it in earnest this fall and have found it is very effective to create a warm and comfortable
cabin. Located in the main
cabin,it backs up to the
head with venting that turns the closed
head into a great drying room.
I have burnt wood (bulky) and compressed
logs (not hot enough, lots of ash and smokey) but have found charcoal briquettes to be the most convenient and hottest so far. Will be trying lump charcoal next season.
I do have smoke and CO detectors in place and would not leave it unattended for prolonged periods, but it has been a great way to extend my season by being able to warm the boat at
anchor.
