last year this time we headed out for the night [wife said wed be backin an hour it was about 10degrees]
advance thinking told me to take a tarp along and we found that throwing it over the bimini canvas and securing it down turned my little 4.6mt half cabin into a nice one bedroom bedsit
im sure the rum helped and our offgassing but we were surprisingly warm allnite
oh and the offgassing didnt seem to deter the fish
i did forget we had thermos on but i think the rum negated my memory [they were only $20 from rays]
if ya can keep out the breeze its actually beeeutiful!
