There have been a few posts about the arrangements for the BRe centreboard, which appear to have been problematic on some boats, but nothing that I could find on the BR20.
Here’s a brief description of the system on the BR20 to be going along with. It’s fairly simple: use the downhaul to pull the top of the pivoting centreboard aft and use the uphaul (on a 2:1 arrangement) to pull it forward. The downhaul line is held in position with an auto-release Clamcleat, so that if the centreboard touches bottom, it releases with a loud bang. The uphaul is led around the starboard side of the centreboard casing via through-deck and cheek blocks to a large plastic Clamcleat. Both lines are within reach of the helm and the system works well.
Attached a photo of the centreboard in which the downhaul is easy to see - it’s the brown three strand line fastened to the black bullseye fairlead. It goes through a bullseye fairlead on the end of the slot and then to the auto-release Clamcleat, both out of frame, bottom left. Part of the uphaul (a black line) can just about be seen underneath the aft edge of the wooden infill. It’s secured on the port side, passes through a couple of through-deck bushes in the top of the centreboard and then on to a through-deck block in the starboard centreboard capping. From there down to the cheek block and then along aft to the big plastic Clamcleat, attached to the side of the centreboard casing.
