The DM-3 works great, it measures 2.15 X 2.75, and weighs just under a pound per foot. Note that it's made of 6061, which is a stronger alloy (by 20%) than the more usual 6063, so if your replacement mast is of undeterminate alloy, go a bit heavier. jerry ----- Original Message ----- From: "Chris Smith" <chris.r.smith@gmail.com> To: "For and about Montgomery Sailboats" <montgomery_boats@mailman.xmission.com> Sent: Monday, March 18, 2013 11:48 AM Subject: M_Boats: Mast sizes
Hello all,
I know that there has been some discussion on Mast length (which I think was settled around 18.5'), but I've got a question about the widths. I currently am using a cut down mast from a catamaran that, from looking at pictures of M15s, is WAY oversized - adding not unconsiderable antiballast.
I had the information once, but have forgotten. Here is the resource I was using from Dwyer Mast Company.<https://www.dwyermast.com/families.asp?cat1ID=20&cat1Name=Masts> I believe it was the DM3 or DM4, but I can't remember.
How much wiggle room is there in mast sizing? I purchased a couple masts on the cheap last year, then found out they were a bit slimmer than they should be. I'd hate for them to bend while out sailing..
Now I've found one that they guy says is 2.5x2 at this craigslist post.<http://chicago.craigslist.org/nwc/boa/3681294101.html>
Thank you, my collective Montgomery brain!
