Great quality and easy to to install and ok on flat surfaces but i have had real problems trying to pull it on some sands as they dig in more like an anchor and also some of our slipways are cobble stone and they really struggle on this as wheels are quite small and hard and get stuck in cobbles ,i have them on a 330 inflatable with 6hp outboard ,i hope this helps
Bought for my 10feet long rubber sea dinghy. Briliant set of wheels well worth the money strong durable and lightweight. Top marks i well recomend these.👍
