10 hours of work- THE BOAT!
probably the sickest cardboard boat ive ever seen. double decker bus. they piled 14 people onto it. it didnt last long.
this was my first year attempting this. i had never even seen a cardboard boat before. it was fun as hell though. we had probably 10 people building it, took about 10-15 hours over 2 days and costed about 100 bucks. we piled 6 people into the boat and it floated for a good 4 minutes.
the goal is to make it to the island princess (big boat) and back and then once you get there you just start attacking other boats.
