Design 2279 - Agena

This certainly looks like a rule beater to me. I haven't come across any design like it in the files. She has a daggerboard that is deployed through a lead keel "shoe". The objective was to have her rate as a centerboarder under I.O.R., which was successfully done and for this she received a favorable rating. Looking at this daggerboard "schematic" there is an end-plate at the bottom of the board which is also made of lead (500 lbs).

We don't know a lot about this boat. I can see from looking at the sail plan that there is a Concordia emblem at each end of the cove stripe (star + moon). The files say she was built by Concordia and Afterguard. Could Afterguard mean the owner and his crew finished the boat? She is built of fiberglass and was launched in 1979.

Here are the plans.

Principal Dimensions
LOA 47'-0"
LWL 36'-0"
Beam 12'-9"
Draft 5'-0" (board up) 9'-1" (board down)
Displacement 23,762 lbs
Ballast 10,578 lbs (outside) 870 lbs (inside) 500 lbs (daggerboard end plate)
Sail Area 920 sq ft


  1. Brice, I remember hearing something about this boat during the winter of 1976-77. Was working in Annapolis then, and building a Britt Chance 41' daggerboard boat. There were several designers trying this out for about 2 years.

    Never heard anything about this boat being raced. I sailed on the Chance boat for 3 seasons, including LI Sound, and the '79 Annapolis-Newport race. The vague recollection I have is that "Agena" was indeed built by Concordia, but they had a collaboration with Mark Lindsay to build glass/epoxy composite hulls. You might contact Mark and ask if he has any knowledge of this boat.

    Very interesting interior, too, with big galley, nav station, and head aft.

  2. I worked on this project for Agena's owner. (I believe that I'm in the picture posted above, poss. standing at the mast??) The project started at the now defunct Gray's boatyard in Taunton, MA. Male molds for the hull & deck were constructed at Gray's. The hull & deck were of epoxy & kevlar. (We nicknamed the boat "Kevlar Queen") The hull mold had channels running from keel to sheer. continuos lengths of Kevlar strands were laid into the channels to form ribs in the finished hull.
    The project was a collaboration of Concordia and the owner's crew. The hull & deck were tranferred to Concordia's Smith Neck facility for completion. Bulkheads were of Kevlar with foam core, they had a lip that fit over the interior ribs and were bolted and epoxied in place.
    The plug for the keel was constructed at Concordia by Chris Gray (Chris also worked for the owner, following the project his family's yard in Taunton to Concordia) Eric Goetz poured the keel at his shop in RRI. The rig was manufactured by Shaefer Marine in New Bedford. Eric Hall (now of Hall Spars) oversaw the rig construction. Rod Stephens came up to Padanaram for a shakedown sail shortly after launching. Due to malfunctioning of the lifting mechanism, the daggerboard (approx. 1,000 lbs) was lost on this shakedown cruise, somewhere just outside the harbor, never found it.
    The boat did some racing (Buzzard's Bay events, Edgartown Race Week, Marblehead-Halifax) but was not really successful. The interior was very elaborate which negated the idea of the lightweight Kevlar-epoxy construction.
    For some time the boat was chartered, mostly for cruising. Last I heard it was in Sippican Harbor, Marion, MA.

  3. I tried to redesign this very original S&S from pictures plan, without any photos :
