Hello All,
Over the years, I have benefited from the many projects shared on the forum. About 16 months ago I embarked on my own build. The design is B & B Crowninshield Design 149, also known as Gypsy. Designed in 1901, she is 22' LOA, 14.5' waterline catboat. Unfortunately, the build has come to a halt due to a recent foot surgery. So during this downtime, I am working on drawings for some of the metal fabricated parts. That's what brings me to the post. The CB is supported by a unique (at least for me) mechanism that hooks over a pin through the bedlogs and is secured at the top of the CB trunk. I find it an interesting design that would make for easy removal for repair. I share this design with you all looking for comments on the design.13160

Harold-
Thank you for introducing me to another interesting historic small boat design. There are others more qualified than I to comment on the centerboard mechanism, so I'll just append what Wikipedia says about the design of Gypsy.


"The Gypsy (previously known as the Witch and the Wren) is a historic catboat (https://en.wikipedia.org/wiki/Catboat) whose home is in Wareham, Massachusetts (https://en.wikipedia.org/wiki/Wareham,_Massachusetts)....Her design was influenced by the "Seawanhaka Rule", instituted at the Seawanhaka Corinthian Yacht Club (https://en.wikipedia.org/wiki/Seawanhaka_Corinthian_Yacht_Club) to govern important characteristics of racing boats. She has a spoon bow, low freeboard, and long overhangs rising out of the water fore and aft.

Beautiful hull! The centerboard hanger is reminiscent of the fitting used for the Beetle No Man's Land boat shown on fig. 63 in Chapelle's American Small Sailing Craft. I'd like to see the rest of BB's design.

It looks to me like the top eye requires a bolt or pin to keep the board from inadvertently being pushed upward if it touches bottom with the board down. I can't distinguish the instructions on my phone if that is in the comments.

I hung a 1/2" thick steel CB on a similar hook built into the board. It worked well and made it easy to install.

I mean that particular design.

Thanks to all who chimed in on the CB mechanism. The CB pivot is located near the hook that fits over a pin in bedlog. There is indeed a removable pin at top of arm to allow for easy removal of CB. Glad to hear no operational issues were identified by the forum members.

I have chosen to strip build the hull and fiberglass inside and out rather than carvel planked.
