Thanks to Ed Ferrier for helping me think some of this through

I made units for two different boats. It all still needs a good testing, so far it worked (kind of) once in a row


Specifications:





Unit for #7603 (N&H) - Oval Alum. Mast


Also made a unit for #7603, with its narrow mast partners and aluminum mast. Even Simpler. Put notch in the mast butt plug that goes inside the aluminum masts (shown while removed from mast for purposes of the the photo. The notch fits right over the 5/16 in. bolt that is part of the structure of the unit. This is to act like a hinge as the mast is rotated upward.

Seeing that boats from different builders are enough different in thie past partners area, that I now think you are likely buiding a custom unit for your boat if you try to make this device.











Unit for #11867 (Allen) - Wood Mast

Photo of Mast Butt receiver, would have to be a different design to receive a modern aluminum mast butt. Also would need to be mounted differently for a boat with narrow (standard width) mast partners



Shows how the swinging mast butt receiver is hinged, using two old small racelite straps



Shows how easy the device is to install and remove. The rubber band helps hold the receiver in place while you drop the mast butt into it.



Photo of Dynema shroud extenders. These connect to the bottom of existing upper shrouds. Run thru the upper shroud chainplates and cleat off using the existing guy cleats. Purpose is to stabilize the mast as you are pushing it upward. I did not have it adjusted right, so really they didn't do anything, but would probably be useful after I used the rig a few more times. So lets call them a potentialy helpful option?

To help hold mast butt in the hinge unit while walking it up, I have added a larger bracket to hold the mast butt. And added a line to quickly tie it in place as well.
