Subject: Looking for m31 mast specs- please help

Hi
I am the owner of a mariner31 dismasted in Grenada's Hurricane Ivan last year. I am trying to find out the length and specifications of the masts so I can get some new ones made. If anyone can help it would be really appreciated.
Suzie.

Main Mast Height 33' 4"
Mizzen Mast Height 25'


The info was a couple of posts down,(by Randall).

Suzie, would be curious to hear how building the new mast goes. I'd assume that, given the dimensions at the foot of the mast (from the pedestal you probably have) and the height, a carpenter could figure the tapering. (But what do I know?)

If/when you get it, could you send for posting any more mast specs you glean? The question of mast specs seems to come up quite a bit.

Will post any new info I get. I'm trying to get wood here in Grenada, at the moment the choices are pitch pine(probably too heavy) or cedar. What d'you think?

I only wish I could answer questions like that. Sorry, I don't know enough about woods.

Is cedar flexible enough? It's always empressed me as being rather brittle.

Seems to me if your choices are limited, weight should not be the primary consideration. Remember, Moitessier built his masts for Joshua out of telephone poles. That something is not ideal speaks nothing of its adequacy.

What about snagging some aluminium pipe and building them up with that? If anything, that would seem the simpler option, and it would answer to both strength and lightness.

Good luck.

Suzie,

Here’s a mast specs clue.

As you may know, Far East yachts built the H-28 for years. And so I’m supposing that in drawing up the M31/32, Oberly drew heavily on H-28 elements (along w/Garden’s 35 ft ketch, which he also built).

To that end, I was thumbing through SENSIBLE CRUISING DESIGNS by L Francis Herreshoff the other day in which there is an essay on H-28 construction. Interestingly, on pg. 26 and 27 you will find detailed drawings of both main and mizzen design. Additionally, there are drawings for the mast head hardware. Both drawings are nearly identical to the masts and hardware on my M31. Obviously, “idendical” refers to design, proportion, construction, and materials—NOT to measurements. Again, if you’ve got mast height and measurements for the base, it seems the rest will follow.

Don’t know where you are in the process of replacing your sticks, but thought this might help.

RR
