My boat, Hull #15 has the true cast iron swing keel with the trunnion lift mechanism. I purchased it last winter, I've been learning as I go. I had the mechanism exposed as much as I can without lifting the boat into the air. I greased the threaded rod underneath and the mating surfaces inside the cabin behind the crank. It ran well for a while but now, at the end of the season, the metal to metal sounds are returning which seem to originate at the bearing surface behind the crank. The last 20 or so cranks to pull the CB horizontal are a bear. I've broken the roll pin that fastens the crank to the end of the threaded a couple of times but not since I greased the threaded rod. The glass on the corner of the centerboard trunk has also cracked from the stress of cranking the mechanism. I'm not sure if wear on the pivot bolt is a concern but the neoprene gaskets could use refreshing. I'm hoping to paint the bottom in the spring. The will give me the opportunity to take a closer look at this and implement any improvements. As a newcomer, I really appreciate the forum.

We only made about 12 with that keel it has a hand crank and a threaded rod driven through a trunnion block. What are your concerns about it? Stan,paintboy

When you say your boat has a cast iron swing keel, do you mean the standard shoal draft keel, with a cast iron centerboard? Or does your boat have a true swing keel? My '76 has the combination shoal keel and cast iron centerboard. The centerboard is raised by wrapping the pennant around a sheet type winch mounted just inside the companionway. It only takes about 10 half rotations of the winch handle to bring it up all the way. I've never heard of a Monty with a true swing keel, but your description sounds like it may be.

I have a '74 M-17 with a cast iron swing keel. I have not seen much conversation about the early swing keel. Cranking the CB up and down I lost count at 120+ revolutions of the crank. This is a bear on the way back to the dock.
Has anyone made any modifications to an early boat to make the process of cranking the CB up and down more efficient? Sailing the boat is a joy except for this chore.
