Genoa Block Adjuster - stbd side: fwd end. Garhauer block on Antal car, with Lewmar cheek block at end of track. I had to add a second bale to the car for dual-directional hauling. The Antal car fits the 1" T-track OK, and it has a nylon insert to help it slide, but the friction is still too much to allow it to be moved under much of a load. That means I need to slack the sheet in order to reposition the car if I don't want to tack to the other side. I usually adjust the windward side while there's no load on it and then tack over; then I can adjust the side that had been under load. Sometimes I'll feather the genoa and shift the car without tacking, but that usually requires using my other hand to keep light, variable pressure on the sheet to keep the genoa from flapping itself to death. In spite of this, it's still a lot more convenient than having to step out onto the side-deck to reach a pinned car in order to pull the pin and reposition the car.
The dual quick-links and pad-eye is an attachment point for spring lines at the dock. They (there's another set on the port side) also serve as turning points for the boom preventer lines on each side that I run back to the cockpit for quick release.
