Propane appliance work on boats

[Hgye]

I notice that TSSA's scope does not include propane work on boats.  Is there another ticket that is needed to do work on boats, or is it unregulated?  Thanks.

You should contact TSSA to be sure, Toll Free: 1-877-682-TSSA (8772)

I believe what you're referring to falls under the RV.1 and RV.2 certificates. (Recreational vehicles technician)
