So is a 13kg weight saving worth 200 on a boat/rig/trolly combination that weighs around 100kg?

We are talking Finn's Rupert, the cradles and bow supports (and presumably Mr Cobb meant same cradle, different frame) probably have to be a tad more substantial than those for an International Moth. Its odd, I've had a bit of a trawl round, and no-on seems to publish the weight of their trolleys.

I don't know what the actual saving was, but it was very significant on my IC. I also like floating trolleys for getting the boat on and off. In my case I was quite sure it was money well spent.

True. A genuinely light weight trolley would simply snap in 2 under a Finn.

In the musto and 49er when you are trying to get sails up and launch on a windy day the weight in the trailer is pretty handy to keep the boat from flying off. I would not want an aluminium trolley in these boats as the weight saving does not get you reduced container costs or transport costs to any measurable value so what is the point. Maybe in a Finn where the boat is so heavy that you want to reduce weight on the shore but in the lighter boats it is not so obvious.

Maybe it's just I'm used to having old trolleys, but I always saw the key benefit of aluminium trolleys was more to do with longevity and lack of corrosion.

Too damn right!

I'm going to try this, take the sail, dagger, rudder and any loose bits out of the boat then pull it up a slipway. They probably weigh 10-15kg, the difference between a steel trolly and an ally one. The difference is more obvious in light boats, a Finn is still a big old lump on shore even with 10kg less trolly to haul up the slip.......

Keeping your tyres inflated also makes a massive difference. The rolling resistance of soft trolley tyres is considerable.

I have got puncture proofs on a couple of mine, definitely worth the investment.
