I'm going to try this out when I re-rig my boat. Not sure if I'm going to go cabin top or not. One thing the J's do is have the helmsman grind in the final few inches on the sheet and I don't think this would be possible with the winch on the cabin top.

:: It looks like most boats have gone to cross sheeting or

:: For those not familiar with the lopez block, it is a cam
:: cleat mounted to a block. This allows you to pull in the
:: genoa sheet and cleat it to stay in place before
:: wrapping it around the winch. These are used on the J/24
:: for example.
