Well i dont know when to stop with projects abd faffing about. As some may know i have a 10` Dinghy mould here ready to make a few when Bohemian is done this summer....yes it will be Honest An idea like some folk have is to to take a bike with themselves while cruising, i have one which is to to carry a motorbike, this being a Honda Shadow VT600C which weigh in at 200kg. good low centre of gravity and 7` 6" long , in the 10` x 4` GRP Dinghy. I can sort a lift frame for it and tow arrangement but at the minute its carrying it and if you think it would be stable on the canals. The bike weighs as much as three average people so i reckon it will be ok and as said the low center of gravity will help as i have designed it in my head to sit low in the keel with a frame i can drop the bike into with out the need to tie it down. Thought apart from being mental please

Why would you want to carry a 200kg motorbike around on a dinghy? Unless the engine is revving and there is a chain connection to the propellor?

Too risky I think the dink would turn turtle at the slightest opportunity. This would obviously be unacceptable as it would result in total loss of the motorcycle. A dinghy just isn't stable enough. My 2p as a keen dinghy lover Maybe it could be made more stable with some sponsons

It would but when you tow a dinghy behind a boat it is subjected to some knocks here and there and can get caught especially in locks. I know someone who had a dinghy overturn while being towed out of a lock and the dinghy was empty. Eta and 3 blokes would probably float whereas a motorbike would sink and its more valuable than the blokes.

Maybe get a wider dinghy then.

Outriggers?
If its rigidly attached I suppose it might work but I still think something unexpected is going to happen.

Yes outriggers. They use bamboo ones on the sea going quite narrow wooden boats here in Indonesia. Bamboo is relatively light and very strong and cheap out here, but doubt it's readily available back home.

Quick one, either outriggers then or make a small pontoon type dinghy, 10` x 6`. Out rigger easier, i can build them into the hull. chow for now. ave a good day all Captain Faffer

You'll stand a much better chance with a catamaran pontoon, which will also make getting the bike on and of easier, I reckon. But all in all, I don't think that it would be practical enough to waste your valuable time on, as you have many more projects on the go, haven't you ? If you continue with it anyway, I still wish you success. Peter.

Would agree with most of the former posts. Would have thought a dinghy a too unstable hull shape for such a heavy small area load. You were saying that it is only about the weight of three guys, maybe, but they don't sit on one another's laps in a central point, it's a spread out load with a low centre of gravity. The other bit that concerns me, is loading and unloading, when you move the weight off centre. I would have thought that could be squeaky bum time. As has been said, a cat pontoon would be more stable. Outriggers are IMO a step in the right direction but that is only a step towards a proper multihull. (The other thing with a pontoon is that you could moor it bow or stern tight square on to the bank and get the bike on/off via a ramp) "Victoria Plum" with his push garage (for electric mobility scooter) SAM_1473 by mudlarker2, on Flickr

Why not just buy a smaller and lighter bike to be the Boat Bike?
