Design 1905 & C1 - Dyna II and Falcon

Two boats were built to this design by Palmer Johnson of Sturgeon Bay, Wisconsin. Dyna II is a sloop. The design brief was for a (somewhat) luxurious cruiser/racer. Falcon is a ketch and was designed strictly as a cruising boat. The design was extensively tank tested. The year was 1969.

We have no images of Dyna II but that's Falcon shown here.

Here are the plans for Dyna II.

Here are the plans for Falcon.

The following images are both interior and exterior shots of Falcon. This is a good example of using a race-worthy hull as a platform for a cruising design.

Principal Dimensions
LOA 50'-11"
LWL 35'-0"
Beam 12'-0"
Draft 7'-4"
Displacement 30,285 lbs
Ballast 15,500 lbs (outside) 1,000 lbs (inside)
Sail Area 1,090 sq ft


  1. My family bought Falcon in 2006, when she was lying Washington, DC in a deteriorated condition. She's now lying Solomons, Maryland. We have been working on her restoration ever since, and it is roughly 80% complete - so far, new sails, new standing and running rigging, a complete rewiring of the electrical systems with new power management, a rebuilt deck for the doghouse, new electronics, new ground tackle and repainted topsides. We expect to install a new windlass and replumb the forward head with a Y-valve for offshore sailing and take her to New England for the summer in a year or two.

    Dyna was sold in Oxford, Maryland a few years ago, I think in 2008. She was also in a very deteriorated condition, and the new owner was planning to restore her, doing most of the work himself. I haven't heard about the progress, but wish him well. These are wonderful boats, and their designs have stood the test of time.

    1. I am the granson of Clayton Ewing who had Dyna built. I have a model of her 51" tall, 45" long and 13" wide in a glass case. She is glorious. Aluminum hulls were cutting edge technology, thus they have stood the test of time~!

  2. If this is the same "Falcon" from Chesapeake Bay area, my father owned it in the late 70's. I'd be interested in sharing photos. The model of it was on display at the Annapolis Yacht Club. It's either there now or in the possession of a family member. ---Lisa LTQLIN@gmail.com
