DIY Floating ATV
#42
Hello MN your setup looks good, but will you have enough flotation? I guessed at the dimensions/volume of your floats. 5”(H) x 12” (W) x 98” (L) x 2 (Floats) / 1728 (# of cubic inches in a cubic ft) x 62.4 (weight of cubic ft of H2O) = 416 lbs. I know the tires will add to this but will it be enough.

I don't know. I've seen plenty of guys float there quads through deep water simply by getting off the machine and the quad floats pretty well. I'd give the extra flotation about an even chance depending on rider weight. If it were me on it, it would probably sink to the bottom faster than a rock.

Never saw one turtled. Have seen guys walk alongside their quads in really deep water. Don't recommend it up here. Water is usually very cold.

When I tried it with the setup in the last picture, it floated, but just barely, and was hard to keep it balanced, and the board across the middle was really bending. So I made the pontoons larger and stronger and made the cross-board stronger and now it works pretty good. Only goes about 1mph though

The reason I don't walk beside the ATV and let it float on its own is because in spots it's too deep for that. Also it's a swamp with leeches https://atvconnection.com/forums/images/smilies/lol.gif

I am working on a design project right now to solve this! I started a new thread, here is the link. If you guys know people who want to drive their ATVs across the water at a decent speed without breaking the bank please do my survey and pass it on to your friends. We are in process of developing our specs and we are hoping to have a working prototype in December!
