No running rigging or no standing rigging?

Re: Morgan Out Island 28

A little background I recently dropped everything and moved to key west and bought my morgan oi. Only problem is the mast is not on the boat I am missing all rigging running and standing, I see people selling rigging on craigslist but it will be off another type of boat, I really wanna put the mast on but preferrably without a crane if possible to save money.... is that possible? I have seen it online but I do not know if my boat is too big. I am new to sailing but am committed. I just hope getting the mast on wont be too much trouble, I am glad I found this thread. Any info would help about how to get it installed for the best price (preferrably me and a few buddies) and no crane unless its nececarry. Can I use rigging from any boat as long as the mast is the same size?

Re: Morgan Out Island 28

So are you missing the mast as well as the rigging?

If so then you have a project in your hands.

The cheap(est) way to remedy that is to find a used mast that would be suitable.

The very first thing you want to do is find out what the stock mast dimensions were. Better than dimensions would be the moments of inertia in each direction.

Morgan was bought by Catalina which is still in business so you should be able to talk to them for that info. Also wire sizes for the standing rigging and mast length.

Now you look for the replacement. On a weekly basis you want to try search tempest or another Craigslist crawler. A better option would be to call all the boat yards and marinas in a 50-200mi radius asking if they have masts they want to get rid of.

The new mast needs to have the same dimensions or maybe slightly bigger. Wall thickness is critical, dropping even 1/32nd of an inch can give you a 10-20% drop in bending moment strength. When you go to look at the mast take a micrometer to check wall thickness.

If a mast has the right section but is significantly too long you can cut the bottom to get the height you want. This will entail moving the spreaders too.

OIs used very a very wide shroud base so you will likely née to install longer spreaders. Should just be some wood working and a bit of painting to make your own.

Assuming the mast comes with standing rigging lengths are probably not going to be right. As long as the wires are big enough all you need to do is cut them to length and install Norseman or Sta-Loc terminals yourself. Practice on a cutoff piece before proceeding with final product. Before you cut the stays look for which end has the better existing swaged end and cut the worse looking end.


A mast that was a bit longer, 2 maybe 3 feet at most would be fine maybe even desire able since the OIs were under canvassed to begin with.

Re: Morgan Out Island 28

Fortunately I do have the mast I just need the standing rigging and to step the mast. But you did answer my question about the rigging. Now I know I can just cut to the demensions I need. Is there some type of inline calculator that I can use if I know the height of the mast? And what wall thickness would you recommend?

Re: Morgan Out Island 28

I will call catilina in fact the rigging I was trying to get was from a catilina around the same size. And thank you so much for your help!

Re: Morgan Out Island 28

Verify mast length, size, thickness and spreader position matches what you have. You may not have to stock mast or here may have been multiple stock sizes over time.

Get lengths and diameters from them. There are likely to be at least 2 diameters. Ask if the lengths they give you assume a turnbuckle at one end and toggle at the other. Find out what length they are assuming for the turnbuckle.
