Yawl

I have a 36' Morgan OI, sloop rigged. I want to add a mizzen mast. What would be the best way to set up the standing rigging?

Re: Yawl

That boat has an aft cuddy, right? If so, I think your biggest design hurdle would be how to step the mast, not how to set up standing rigging.

If you're going to do this right, the completed mizzen will probably cost more than the entire boat is worth.

Re: Yawl

If your boat was originally rigged as a sloop the main mast will already be stepped too far aft to allow you to put a mizzen mast on without grossly affecting the balance of the boat.

For instance, my boat, an allied seawind II was available as either a cutter or a ketch. when rigged as a cutter the mast is moved aft by about 1.5'-2'. This balances the load on the keel and rudder and allows the boat to sail neutrally. If a mizzen was introduced to the boat with the mast in the cutter position, then there would be a tendency for the boat to round up, or at least have horrible weather helm.

I was going to use a simple tabernacle and I think to put chain plates similar to the main. There is a fair amount of room aft of the cabin on the deck. I can't find any examples of a yawl rig on this hull.

Why, for heaven's sake, I wonder why that could be???

Re: Yawl

The compression loads on the base of even a small mast can be surprisingly high. A tabernacle will not change this. The deck will need to be reinforced and likely a compression post installed under the mast step. Another consideration is how are you going to handle the sheet lines. As the others have said this will not be cheap and one wonders why you would want to do this? you may also have to reinforce the hull where you place the chain plates. most builders add extra laminate to these areas. Also making modifications like this can adversely effect the resale value of the boat. Need any more reasons for not doing it?

Re: Yawl

Listen to the folks who posted above;I suspect you may want a mizzen to hang radar or some such, this can be done without installing a 2nd mast.
If you are trying to get more sail area to go fast ,best to have a sailmaker take a look at your inventory or spend some boat dollars on a feathering prop etc.,but from what I'm told ,it's a waste of time to try to teach a pig to sing, and it only annoys the pig.

Re: Yawl

Why would you want to do this? It would seriously unbalance your boat. If you're dead set on wanting a yawl, I would recomend selling your Morgan and buying something like an Alberg 37 which is already rigged as one.

Re: Yawl

My boat is a ketch with a very small mizzen, so it is similar to a yawl. I really don't think it is worth it. Under some conditions it helps to balance the sail plan, particularly when you put a deep reef in the main or just drop it, but most of the time it is more of a nuisance. Stick with the sloop rig and see how you can improve it to get what you want. For example, you may want to go with a roachier main and full battens if you want more power aft of the mast.

Look into purchasing a ketch sailboat. The effort, expense and then you have an untried design.

The ketch threads makes everyone want to have one.

Re: Yawl

I lived on an OI 36 for a couple of years and cruised a few thousand miles on it. I had no problem with the sloop rig at all. Helm was very balanced on all points of sail and in winds from calm to gales with triple reefed main and storm jib which is as much wind as I ever experienced.

Cannot see any practical benefit to making a yawl out of the boat, and in fact would most likely totally unbalance the rig.

As pointed out, the cost could easily be more than the value of the boat. It would require significant bracing and reinforcing to hold the mizzen.

For curiosity's sake, why do you want to do this?

Re: Yawl

Not what you asked but Pearson made a pretty 39 Yawl.

I live on this Morgan and any increase in sail area might help. I love the room but she ain't fast. Only a thought.

This is not, repeat NOT going to make this boat any faster. What you really need to do is look at larger better shaped headsails, and maybe even a main with full battens and as much roach as you can fit under the backstay.

When you've done that, invest in some light air sails.

All a mizzen will do to that boat is ruin trim, and probably make it slower.
