I am attempting to modify the anchor system on an older glass driftboat. The boat has a rear deck with a storage area where the rope could pass easely to get out of the way. I (think) that I would perfer to have a center pull system, but I really do not want to mount a pully or the rope to the floor under the rowers seat. A side pull system, where the rope runs along the gunwale, is also an option. Please help
