This is great! I'm really getting a lot from reading thoughts on all sides of this debate and I really appreciate all of your comments! What I have done so far is: Applied mildew/mold resistant primer to the hull and put reflectix over that. The thought being that if there is any mold build up behind the insulation it will be kept to a minimum. I have ordered the hypervent for the settees and v-birth since most everyone agrees that it is a good thing. This leave me with venting or dehumidifying... Since I will need heat either way, I need to choose an appropriate heater. My boat is on 25' so it isn't much space to heat, and I do have shore power. So to redirect this thread for a sec, who is using what heaters and any opinions (and I KNOW you have them
! ) on what may work best for my small space. THANK YOU ALL!
