Traditional, heavy vessels have some advantages
when it comes to docking, particularly in spaceous marinas and harbors. I remember docking gaff-rigged, full-keeled 20-25 footers under sail a loooong time ago. As long as one had a fairly open shot at an upwind slip, this was easy as pie. You dropped the jib, adjusted boat speed and turned into the wind while lining up the bows with the dock or slip. It was important to keep one hand on the boom (with the main luffing) until you were satisfied that you did not have too much speed on; in which case you pushed the boom out to brake a bit (or even to back out in case of surprises). Then you just walked to the beam or the bows as soon as you were about 10 feet away from the dock. All the while, because of its mass and directional stability the vessel would just keep moving pretty much in a straight line, though continuing to decelerate. Much later, when we had little children and bought a 35 ft Drift-R-Cruz houseboat (with a single 250 hp Z-drive engine, practically no keel and more windage than a sailing vessel under reefed main) I had to learn the hard way not to line up "Rivendel I" with the dock or lock wall, idle the engine and walk to the bow to fasten a dockline, as she would tend to go every which way but straight ahead......The real problem for all vessels trying to dock in todays cramped, overfull marinas with narrow turns, fluky winds and tight slips is that you can't go really fast (unless you know your slip, your vessel and your engine very, very well) and yet you can't go really slow without losing steerage unless you have a big, highly efficient rudder or a big, full keel. In the latter case, however, it is pretty hopeless to try and execute a narrow turn at low speed. So, in tight docking situations, I will happily take a big rudder over a big keel any time .
