We love the Winchrite. It goes on charge the night before sailing and has a charge that lasts us all day. Great for raising the main and sheeting the head sail.
I do find it a lot bigger than a winch handle and worry about it leaving the winch in heavy weather
The admiral just reminded me that the best time for its use is when we need to reef and now she can handle the whole operation by herself which is great for me as I don't have to put down the beer
We have had it for 5 years now and got ours by post direct from the states, forget which web site but the service
was good and has helped us take some of the load off.
A warning came with the unit Not to use it to raise or lower someone up the mast but when we were trailer sailing we used it to raise the mast. Another time we improved our sailing experiences.
Its a winner.
