Homemade caterpillar track for Sand....

[flooky]

I got the same problem, live 100 yards from the beach, got to get stuck in traffic to get to the slip.
I got a bigger rib for the slipway,(sounds flash..it aint) weekdays (no traffic), and a 3m with a 9.9 same sort of weight as yours,i use a launching trolley on stone and sand, but some times i run the rib on lengths of plastic water pipe (sink waste size) after i get to the beach...
sand hopper tyres are crap they break use the rubber ones,
it agro but beer and rum help..(aint got to drive ..cos no slip)i am not a piss head you understand....i just got issues..

Many of the catamaran sailors down here are using balloon wheels over soft sand.

You can just manage a 145kg tornado single handed, and it is easy with two people. I would have thought a well balanced beach trolley should easily manage a 100kg rib. The wheels without treads seem to be much easier to handle.

These are the ones we use.

My old trolley for my 20' cat (190 kgs) uses the knobbly version of those. My new 17' cat (carbon fibre - 115 kgs) uses the 18 x 9.5 ones. These new are better than the larger ones - they are much more flat in profile and have the same contact width. Can actually run up the beach pushing the boat.

Interesting, the sand is really soft where we launch and there is often a bit of a bank to get the boat over so the larger wheels seem to work better. Those knobbly ones would be better if there are sharp bits, or a harder base.
