You need to investigate a bit more about how you would mount the mast on your boat and how your sail will attach to it. Prindles, as all beach cats, are designed to step the mast on the front crossbar. So the step is curved and there is a ball or other device that allows the mast to rotate once it is stepped.... there is a good chance that the mast step on your Oday (the part that attaches to the boat) will not accommodate the casting at the base of the Prindle's mast. Nor will the Prindle's mast step fit on your boat without a major modification. What would be delightful is if you could remove the casting on your broken Oday mast and it fit perfectly in the Prindle extrusion....

Question One: have you compared the prindle mast extrusion's profile with your Oday's? Is there any way you can adapt the base, step and extrusion if they don't match.

The next issue is how your sail attaches to the mast. Almost all beach cats attach the mainsail to its mast with a "boltrope" which is sewn into the sail and fits snugly into a groove in the mast extrusion. If your sail's attachment method doesn't match up with the Prindle mast because it uses slugs or the boltrope is the wrong size, you may be able to adapt the sail by finding replacement slugs that fit the Prindle's groove.

Question number two: How does you sail attach to the mast... will it fit the prindle and if not, is it adaptable?

The final consideration is how the mast is supported. All beach cats are fractional rigs. That means the forestay only goes part way up the mast, not to the very top. In addition, the side stays, or shouds are swept backwards so the mast can be supported without a backstay. Think "tripod"... But without a doubt the most important difference is that the beach cat's mast has no "spreaders", because there are no cap shrouds.... the side stays do not go all the way to the top but rather terminate near the junction of the forestay. If you wanted to rig the Prindle mast on your Oday you would need to fit a set of spreaders at the proper height and afix some tangs near the top to attach the shrouds.... Chances are your existing rigging could be adapted and perhaps the bracket from the broken mast can be refit on the prindle....

If your oday is a masthead rig, where the forestay goes all the way to the top, you will need some type of fitting to receive it. If you're lucky enough that the Oday's base casting fits the Prindle, then it's logical that the masthead fitting would work also. Otherwise you will have to come up with another solution because the Prindle's masthead fitting will not accommodate your rig.

So, question Number three is: Can you adapt your existing rigging to the new mast?

Heh,heh... I've just realized that I did not answer your simple question.... but hopefully I've given you some insight into it's solution.

My advice here is that if you have the old mast and all the rigging, you can probably adapt just about anything to make it work. If you don't have the old rigging and the broken mast with its base and top castings, you'll have to be a lot more creative. Good luck

mast replacement

that is some wild reply- my main question was strength- but i guess aluminum is strong!!

Re: mast replacement

Doug , actually your question was would it work, and had no reference to strength. Joe gave you a superb answer detailing the differences that you will have to deal with.
