It's best to put the boat on a trap before inflating/deflating. I did it once on concrete, dragged the boat a little, and put scratches on the bottom plastic sheet between the two pontoons.
They're Railblaza C-tug dinghy wheels. Only issue with them is they get in the way of the engine, it won't turn. I just remove the wheels once the boat is in the water.
I skipped through the video a bit. Sorry. From living most of my life in Moreton Bay and fishing the place for years in a kayak, I can tell you that covering up is the way to not get burnt. In fact, go for a long sleeve rashy (uv protected). Wear gloves, long pants, wetsuit shoes, sunnies, a hat and a buff. Show no skin basically. Occasionally, wet your hat/buff/wetsuit shoes in fresh water. Don't be tempted to use salt water. It will dehydrate you more. Also, how was the boat at speed? Can you feel it flex? I'm considering one of these but I am concerned about possible flex.
Thanks for the tips! The boat is solid, as long as you pump it up to the recommended pressure, which is easy. I had no experience of it flexing & I've been out when it's been a bit tasty & also jumping waves in it.
I reckon to inflate it, put engine on etc., probably about 45 mins, but that's taking my time, strapping down my emergency equipment box, putting wheels on etc. I reckon you could do it quicker. I guess the more you do it the quicker you get. Packing up was a bit tricky at first, but now I can pack it up easily. I use my electric pump to suck the remaining air out after I've released the air valves & also make sure none of the boat sides sticks out past the transome before I roll it & it seems to be okay.
