Heat is a must in the Northwest
With regard to "cold" we in the Northwest can understand your problem. If one is going to use the boat very much then heat is a must. Conversely, boat heat can help extend the season and increase utility and help justify the cost.On our H-35 we have had an Ardic 041-D forced air heater (made by Volvo) since around 1992 and it has really helped improve crew morale. It's a 10,000 BTU unit which I feel is appropriately sized for the boat and our weather conditions. I don't think this particular model heater is made anymore but there are similar units available.We just returned from a short one-week cruise and used the heater every day.There are a lot of considerations and if you like contact me off-line using the Owners directory and mention the deails you would like.
