ISOMAT Boom from a Tanaya 42.
See pictures of what you get below.
Look at Rig-Rite Inc. - Masts, Booms, Spars, Rigging, and Hardware for Sailboats. in their Boom area for a NB-40 section and you can get all the specs.
The boom was cracked in a jibe about a year ago and a repair made. Not the best looking repair in the world, but the boom has been fully functional for the last year including sailing offshore.
The aluminum section is 16'11" in length. Take off 3" to get rid of the repair. With the gooseneck and end of boom fitting, you could have a boom with the max overall length of 17'2".
Proper repair would be to cut and join/sleeve it. RigRite can probably help out with the part you need to sleeve it.
Nearly all of the components are still on the boom, a couple have been removed. Internal lines were replaced during the repair. Boom is basically in good condition.
Buy it and take it away (roof top transportable!) or arrange for pick up by a boat transport company. Or for and extra $25 I'll take it all part and you can have just the pieces you want or just a section of the boom.
A great spare or winter project.
I can store it for 30-days once you have paid for it. I ca do PayPal, but you have to send the money as a "gift" so they don't take out 4% fees.
I would be willing to deliver it to Beaufort, NC, Morehead City, NC or to Oriental, NC for gas money or a couple of cheeseburgers or tacos!
