Shelter, for instance. The Everglades Challenge –– the adventure race that got this boat-building project started –– naturally and responsibly requires that competitors carry a bug-proof shelter. With 300 Florida miles and the Everglades to traverse, I should think so.
Paddlers usually bring a tiny tent. For the trio onboard Spawn, the shelter is two-part: there's the forward state-room below the foredeck, and then there's a tonneau-cover/conestoga wagon shelter that spans the middle of the boat. The edges of the canvas cover are secured with a wide band of Velcro®.
The tonneau-cover not only helps repel water should it come raining or splashing into the cockpit while the boat is underway, it also makes a very cool fort.
So in case the wind poops out, the team won't be entirely at the mercy of the Everglades most annoying native species. I'll probably tuck a deck of cards into the toothbrushes-and-baby-powder personal-care kit for the guys.
You know, in the unlikely event of a boredom emergency.
