...speaking of keels and bunks and rollers, a question on the M17 centerboard. This is a '74 so it's the heavy cast iron CB.
When fully up, should it be flush with the bottom of the keel? Mine will not go up quite that far. The rear end protrudes about 1 to 1 1/2 inches.
I think it is because there is a rather thick pennant line, and I don't know what knot or fastening setup was used but I'm guessing the knot is long/fat, bulky, double, etc. - in short, taking up space that leaves the CB hanging out that inch-plus.
I can see the top of the pennant knot hard against the underside of the pennant hole in the CB trunk - it is as far up as it can go.
At some point this winter I hope to get the boat situated so I can lower the board down and see what's up and maybe improve the situation.
But should I expect to be able to get the CB up flush with the trunk?
Mine does too. Not an inch and a half, not even half an inch, but it’s not flush and on the rollers the centerboard makes contact and not the keel. And there’s a small gap at the joint that I epoxied, so probably a little more protruded before it sprang. My pendant is very thin (6mm single-braid Vectran) and I put some work into figuring out the smallest secure knot (a figure-eight hitch, if you care) so I don’t think there’s much wasted space in there.
