Storing on a houseboat

[pepowdylan]

So we have a older houseboat, and everytime I go wakeboarding I'll definitely be leaving from the houseboat so I want to keep it there. The only place I can come up with to keep it would be in the hull. Theres a lot of storage space down there. Some are just planks of good going across, and some of it is crawl space. We keep floats and stuff down there. Whats the best way to keep it down there? It's just big enough to crawl down there and put it down there.
