Mast support pole 1990 GB 36 Classic

Postby Long Story GB36 » Tue Aug 27, 2019 10:44 am

I have a nice couple that just docked next to our boat with a new to them 1990 GB 36. (Classic)

They want to lower there mast to get under covered at dock but the boat did not come with the support pole to hold the mast and boom. Unlike my 1977 the hing is on the upper most flybridge.

Anyone have a similar model and year who might be able to supply some dimensions and photo so he can have one fabricated?

Thanks in advance for the help.

Our 87 Classic has the hinge on the flybridge and an aluminum crutch. I will take some photos and measurements and be able to post them on Friday or Saturday, Aug. 30-31.

Russ, please see the attached files for the mast/boom setup installed on my boat. The hand drawn dimensions are fairly close but not exact due to the mast/boom in its down position. The basic construction is 1/4 " thick, 1 1/2" wide piece of aluminum strap 16 " - 20" long (approximate), formed into a "U" with the top wider than the bottom welded to an aluminum pipe 1 1/4" OD. Allows for the holding of the boom which is approximately 3" wide. There is a length of rubber with the same dimensions cemented to the inner side of the crutch for boom protection. The support pipe is 45" long with a notch approximately 3/8" wide and 1 1/2" long cut into the base that is used to fit over the welded stainless steel linch pin that is welded to the stainless steel vertical support of the boat hand rail. The linch pin is welded approximately 2" up from the vertical support base allowing for 1/2 " clearance from the deck to the crutch support pipe end. If you have any questions, let me know. The support pipe is also secured to the vertical hand rail support with a couple of SS clamps placed evenly.
Good luck

You could just make a cradle using an 8 foot 2x4 with a one foot piece as a base. Tie line stabilerizers to port and starboard cleats. Fast remedy while you decide. Cut a v onto the top of the cradle.
