Does anyone have a pic that they can share of this setup?

Re: O'Day 30 Swing Keel Rigging

Hello! This is my first post on sailnet so here I go? I have a 1980 Oday 30 win a CB. It too has the line over the cabin and a Kleet to tie off. It isn't very difficult to retract because as you have read it is a neutral balance. Maybe barnacles are the problem. The guy who dives on all the sailboats by me I. The Long Island Sound says that the barnacles can build up and almost make it impossible to retract. He said he manufactured a long angled rod to get up I side the keel and clear the unit. Good luck!

rustyballast wescarroll,

I finally added the block and rigged as you suggested and it works perfect.

rustyballast wescarroll,

Thanks. This makes sense and will rig accordingly. Called Rudy at D&R and he indicated that it should not require such effort to lift. The swing keel weighs about 300 lbs but due to position should not be so difficult to lift.

wescarroll The line from the centerboard ends in a shackle attached to the dead end of a block. A line anchored on the deck loops through the block, back to a cleat next to the anchor point, making for a 2/1 purchase.

O'Day 30 Swing Keel Rigging


The swing keel on my O'Day 30 simply has a line coming up out of the cabin roof, through a cheek block and then directly to the cockpit. The line is cleated off at the top of the cabin near the companion way. This arrangement provides no mechanical advantage of pulleys and blocks and I must pull with an enormous amount of force to retract the keel (both feet on cabin). Does anyone have a diagram they could send me of how this is supposed to be rigged or could you describe? Any help is appreciated before I break my neck or back slipping at some point.

Oday 30 swing keel

I have the centerboard version of the Oday 30, too. It is not weighted, but it is not neutral buoyancy, either, and can use a little help in terms of mechanical advantage to lift it. When I bought the boat several years ago, it had a 2:1 tackle on the cabin top to give additional purchase, and wasn't too hard to raise, but sometime later, since I was adding self-tailing cabin top winches for spinnaker halyards anyway, I ran the tail through a clutch and then to the starboard cabin top winch. Now raising the board is really easy. Here's a picture of the centerboard:

On the same subject, be careful about using a Nicopress fitting on the bottom of the centerboard pendant. After having to replace it every 6-8 months, I suddenly realized it was acting as sacrificial anode, and being eaten away just like a zinc. Next time I replace it, I'm going to try a stainless fork.
