21′ Trihull Expedition Boat
The Mac Daddy of Expandacraft! Great option for camping expeditions. This boat can break down in 10 minutes and the parts fit in the back of a truck or SUV. Not everyone has a yard for a boat on a trailer, so this makes boat ownership possible for a wider market. With Expandacraft, you can change the configuration of your components to fit your needs that day. The same parts which make this large pontoon, can make a 12 foot sit on top paddle cat or an outrigger kit for a canoe. Great for camping and large groups! No loading ramp needed, just a quick 10-15 minute set up at the water front with a couple helping hands and you’re on your way! Scroll through the photos for some previous client set ups as inspiration. With Expandacraft, we always say the only limitation is your imagination!

NOTES: If using deck planks, attach to cross tubes with space between each plank so you can strap things down to the deck. Optionally, for an additional charge, you can have 8′ 6″ cross tubes and an extra deck plank.
Cost cutting tip: Source local aluminum planks for decking and the aluminum tubing for your cross tubes. You will have to drill your own holes and attach the end caps, but this will save on shipping and total order cost.
Does NOT include decking, seating, or any other items shown on the deck in pictures. We do typically offer aluminum decking for this boat package, but due to nationwide supply shortages we are out of stock until at least February 2022. We will keep this page updated when decking becomes available again.
