If you need a heating system you could consider a hydronic system to circulate hot water through the boat with radiators. During the summer months these systems can have bypasses to run through your water heater heat exchanger. These units are diesel fired and can provide hot water and heat all from diesel fuel.
Your best bet is to stay away from diesel cookers. Just stay with your propane. It is sort of a universal fuel.
