Welcome to Cruiser Log Daniel!
You've brought up a topic near and dear to me as I'm in the process of putting a solid fuel stove in our boat and have done a lot of research to ensure that we can safely operate it and the installation is proper.
There are numerous folks with solid fuel stoves aboard their yachts. Some purely for heating, some for heating hot water that is circulated in radiators, and some for cooking. There are special considerations for the installation of a solid fuel stove in your boat. You're not going to be able to maintain the clearances for a home installation but there is guidance available for the installation of a solid fuel stove. The Navigator Stoveworks website happens to have a nice guide on the installation of some of their stoves--and you can get the idea just from reading their installation instructions how you might deal with a stove in your own yacht. Here is a link to that installation info for one of their stoves LINK
In this link, you'll find reference to applicable safety standards and the following info:
American Boat & Yacht Council Inc
Standard A-7, Liquid and Solid Fuel Boat Heating Systems.
National Fire Prevention Association
Standard #302, Fire Protection Standard for Pleasure and Commercial Motor Craft 1998 Edition.
Regarding Stoves Aboard USCG Inspected Vessels: The 1994 US Coast Guard Supplemental Notice of Proposed Rulemaking, (SNPRM, Subpart B--Cooking and Heating Sections 121.202 and 184.202 -- Restrictions.) addresses the 46 CFR 184.202 regulation prohibiting open flames:
"This new restriction is not intended to prohibit wood burning stoves, such as Ben Franklin stoves, or fireplaces with proper doors."
Most cruising yachts don't have sufficient room for clearances required by NFPA standards for residential installations--even the reduced clearances so you'll want to look to an engineered installation or get in touch with a local marine surveyor to make sure your installation is done is such a way that it will be ok when future surveys are performed (else, you won't be able to insure your vessel...)
We're installing a solid fuel stove in our galley (it originally had a combination solid fuel/propane stove there) with an accessory of Trangia
-based non-pressure alcohol burners for summer/hot weather use. Our boat originally had a small solid fuel stove in the main saloon as well, but we will likely put a diesel wall-mount stove there instead.
Most all solid fuel stoves built for residential use are far too big for use in a cruising yacht. You can find a few smaller stoves (for example the Morso
Squirrel is available here in the USA and some of the Jotul
stoves are almost small enough) but you are likely to do better with a stove made for boat use. The Fatsco
stove company has a few, as does Navigator Stove Works
. The Lunenburg Foundry in Canada used to make boat stoves, but I believe their patterns were purchased by Navigator. The Washington Stoveworks (no longer made) and Shipmate stoves made by the Stamford Foundry are no longer available new, but you can find them used sometimes. The Concordia
company can sell you one of their stoves, but it will be dear in cost as they're not in production and are only special order. Dickinson Marine
makes a wall-mount saloon stove for solid fuel and Paul E Luke Company
makes some solid fuel stoves.
Once you've decided on a stove that possibly fits the space you have (with a proper installation for the reduced clearances of the boat space available) you'll be also most interested in the chimney and thru deck fittings required. We're doing our installation now and we have a "moat" style thru deck fitting that one puts water in to keep the deck around the pipe cool. Is this
the same type of piece you're talking about already having for your stove? What diameter is the thru deck fitting that you have?
We also have designed a "double pipe" installation allowing air space to keep the flue gases hot and the deck cool. The Class-A double wall stovepipe made for house installation will not typically fit your boat installation so if you choose to do a double wall installation, you'll probably have to have it custom fabricated (as we're in the process of doing right now) for your application.
How much space do you have for the stove? Where will the chimney exit the deck/cabintop?
Looking forward to further discussion.
