Gaff and boom dimensions
« on: May 09, 2021, 09:17:50 PM »
I have recently rescued a Winkle Brigg of unknown date or number from a boatyard. Unfortunately she does not have her gaff, boom or topsail yard with her and so I need to make up some new ones. Would any of you kindly, knowledgeable people know the standard dimensions as I can’t find them anywhere

Hello Mark,
Dimensions taken from WB #107

Low Peaked Gaff Rig, as supplied:
Boom:      3,365mm + Jaws, 44mm wide, 50mm ht. at ends, 62mm in middle. Douglas Fir.
Yard:        2,615mm + Jaws, 44mm square section, Douglas Fir.
Topmast:  2,590mm, 30mm square section at ends, 44mm square section in middle. Douglas Fir.
               n.b. I replaced this with 2,140mm x 45mm O.D. Aluminium tube.
                     In both cases I bolted the topmast to the forward port shoulder of the mast. When using the topsail, secured
                     the tack and clew to the yard and raised it using a peak halyard.

High Peaked Gaff Rig, as used of late:
Boom:      3,710mm + Jaws, 44 x 50mm at ends, 44 x 62mm in middle. Douglas Fir.
Yard:        3,325mm + Jaws, 44mm square section. Spruce.
                Can be about 100mm less but added length reaches the gallows. (Discovered after the event.)

Hope this is of use, anything else, please ask.

Regards,
David
