Re: Camping aboard tri-hull
I've been boat and shore camping for years and have sleeping bags stowed on the boat, just for it. I started out on a 16' tri-hull which had home built lounge seats, a big seat/storage compartment behind the windshield and the middle of the deck wide open. When boat camping, take the seat tops off (2" thick foam) and place them on the deck, insta-bed

The big storage compartment had 4 sleeping bags in it, all the time.
My current boat isn't so comfy since it has pedestal seats, but has more deck space to stretch out on. I cobbled up a cover for it out of a rain fly from an old cabin tent. Look like 'ell but works well as we have been in rain several times and stayed dry. Work much better then the emergency plastic tarp I had in the tri-hull..
Storing provisions in the boat can be interesting. I once opened up some granola bars which had been on the boat for who knows how long. They had the faint taste of fuel and I was burping up gas fumes for the next couple of hours. Another time I was out night fishing with a buddy and grabbed a package of cookies from under the seat.... After both of us munched down a couple I felt a strange tickling on my hand,,, ANTS!!! A flashlight confirmed that the entire package was crawling with the little buggers, ants and cookies were quickly pitched overboard (Ants kind of taste like cookies)
I noticed a couple days earlier that there was an ant trail coming from my yard to the boat,,, and those little buggers climbed the tire, wheel, axle, frame, bunk, hull, under the cover, into the boat and finally discovered the package of cookies where they were partying for who knows how long.
Have fun and don't let the bed bugs (or ants) bite
