Morgan 36T Keel
 
Is the Morgan 36T keel lead or steel?
Problems?

Sailboat data indicates it was lead google the boat name and the information is available to study.....

It was intended as a front line IOR race boat when it was introduced so I'd be very surprised if it was anything but lead.

Thanks for that. I'd never noticed "ballast type" on Sailboat Data before!:o

Why, because of the efficiency of lead?
Also, Whats with the swept keel design (the fin retreats radically toward the Stearn)? Haven't noticed it on other boats.

1974.
Unfortunately, I'm not on Face book. Joined once and got pummeled by contacts from people I had no interest in speaking with!

The shark fin style keel, featuring a lot of sweepback, was the common fin keel design for performance oriented boats in the late'60- mid '70s. This design was generally replaced in the late '70s by "higher aspect " keels which feature shorter chords and less sweepback (more vertical edges).

See Good Old Boat - Keel design: What's best? article

You can see this transition by comparing a boat like a C&C mark II to a Mark III. I have a very positive opinion of the older sweepback keels, as while they may have given a little up closehauled, they were far more forgiving if they hit something hard at speed...

Exactly - it's the densest material allowed for ballast. Denser is better for ballast because it allows the weight to be carried as low as possible, giving a better lever arm.

Lead is also, for all practical purposes, inert so it doesn't require maintenance like iron keels can if not properly protected with coatings.
