Design 181 - Mary Clyde

This could be the only gaff rigged yawl in our archives. Mary Clyde was built by W, J. Howell & Son of East Moriches, New York. She was launched in 1937. The image above shows her with a Marconi rig, which we designed for her in 1957 for retrofitting. Please review the sail plan below to see how she was as launched. She's a nice little shoal draft cruising boat with a comfortable three-berth layout and roomy cockpit.

Here are the plans. We pulled these scans from the microfiche files so they aren't perfect but sufficient.

Principal Dimensions
LOA 33'-11"
LWL 26'-4
Beam 10'-0"
Draft 3'-0"
Sail Area 677 sq ft


  1. My grandfather sailed on the Great South Bay and I believe he owned this boat. Is there any data about her port of call and previous owners>

  2. Hi Bud,

    This is Dave MacDonell III. Your are quite right. Our grandfather did own the Mary Clyde when she was gaff rigged. I have several photos of her from my father. I also would love to know her history after she was sold in the early 50's.


    1. Dave
      I would love copies of the pix
      Can you scan them?
      Blessings to you. Assume you are still on Long Island?
