              While competitive and recreational rowing is the reason                        behind the design, there are other possible uses for it. It                        can be rigged to sail, and being light and easily driven will                        go well with a fairly small rig. A centerboard trunk is an                        easy modification and will not impair rowing performance.                        Some users might want to combine rowing and sailing. If                        equipped with a simple tent and appropriate gear, it will                        make a good “Camping Cruiser”. People who still have some of                      the Tom Sawyer-Huck Finn spirit can take it from there. 
              Neither sex nor age nor athletic prowess are limiting                        factors. Some of the handicapped have become involved                        successfully in rowing. Any group interested in healthful,                        non—stressful, moderate exercise and fresh air may                        participate. It can be as relaxed or strenuous as desired. It                        is non—polluting and non—disturbing. It is the best way to                        observe waterfowl and other wildlife. Competition is                        possible, if wanted. With only one boat different crews may                      race by comparing times over a known distance. 
                
              Museums and other historically oriented organizations,                        particularly those with riverine or marine leanings, may find                        existing contacts receptive to this activity. Many have                        facilities suitable for instruction and construction.  
              Organizations, such as yacht clubs, that have seen the                        demographics of their membership change with the passage of                        time, from mostly young hotshots to more settled family                        types, may -Find a non—stressful rowing program attractive.                        Retirement communities would seem to be a good field for this                        activity. Many have workshops where the boat might be                        built. The materials are readily available and relatively                        inexpensive. Boatbuilding skills are not required. The                        components are prefabricated before setup. Unlike                        conventional boatbuilding, nothing is attached to the floor                        and the assembly is a quick and easy procedure. The boats                        are light and easily transported. Perhaps some who are                        finding golf too frustrating, or tennis too hard on the                        knees, may find rowing a welcome change, and it is done in a                        sitting position. Those wishing to do something for society                        may foster youth involvement. Existing programs for getting                        young people involved in rowing show that all it takes is a                      little guidance plus the necessary watercraft. 
                
              During the steamboat era, before the lumberjacks had                        finished cutting down all the “Forest Primeval”, white pine                        boards long enough and wide enough to make the side of a yawl                        in one piece were readily available. That is no longer the                        case. Such lumber is now just about impossible to find, and                        if found, is very expensive. Plywood is available, and by                        using materials and techniques that were not available then,                        functionally comparable plywood boats may be constructed.                        They have the advantage of much lighter weight, a major                      consideration in an era of high mobility. 
              Quoting from a letter from James Stephens of Marietta,                        Ohio: “I have an idea for next year that our club will back                        that may interest you. We want to stimulate interest in                        rowing among high school kids. There are at least six high                        schools on the Muskingum River, but none has resources to                        enter rowing in the modern, sliding seat, high expense                        manner. We believe we could convince two schools to build a                        skiff apiece and row competitively. Because they are river                        towns we think the boats should be in keeping with their                      history”. 
               There was a time when many river towns depended on                        steamboats for transportation of freight and passengers.                        Some of us regret the passing of the steamboat, but it has 
                been replaced by faster and more efficient carriers. The                        rivers, for the most part, are still there. They are                      available for healthful outdoor activity. 
                
              Each steamboat carried a work boat, called the Yawl, or                        Yawl—Boat. If you look up chapter XII of “Life on the                        Mississippi”, by you know who, you will get a good idea of 
yawl—boat usage. We have here a boat that is, in form, a                        typical yawl, though more slender than some. The old yawls                        were built heavy to take rough treatment, and got even                        heavier as they became soaked. The new boat is built using                        Plywood Taped Seam Construction, making a boat that is                        permanently tight, durable and lighter by half. There is a                      corresponding reduction in material and labor costs. 
              Arrangement of oars may be varied. Four sweeps and                        coxswain is the primary setup, but two, three or four pairs                        of sculls may be used, The boat may be handled by a single                        sculler. Seats are fixed and the oarlocks may be thole pins                        or pivoting metal. The rudder may be locked on center,                        making the coxswain optional. Rowing is suitable for all                        ages and requires no special athletic ability or talent. It                        should appeal to a large percentage of the school population                        and probably some of their elders. Costs should be much                        easier on the PE budget than contact sports. Equipment may                      be built by participants or parents. 
              It is hoped that this project will find appeal among                        scholastic rowers for competition and recreation as well as                        among others at large. Increased awareness of the need to                        conserve and preserve our water resources may be an added                      dividend. 
                
              Plywood was not a satisfactory material for boats until                        about 1940, when US Plywood introduced “Weldwood”, which                        employed a waterproof bond, using the “Hot Plate Process”,                        with thermosetting resins as developed by Leo Baekeland and                        others. Boatbuilders began using plywood by mere substitution                        keeping the rest of the structure the same. Some still do.                        There is nothing wrong with that. Plywood can be substituted                        advantageously for lumber in various areas of boat structure.                      Examples are planking, decks and bulkheads. 
                
              However, the year 1962 saw a major development that                        changed the whole picture of plywood for boats. That year saw                        the debut of the Mirror Class Dinghy, designed by Jack Holt,                        with technical assistance from Barry Bucknell, and backed and                        promoted by the mass circulation London Daily Mirror. The new                        boat eliminated much of the lumber and fastenings that had                        been used only as connectors between plywood panels. They                        were replaced by taped seams, in which fiberglass tape bonded                        with a plastic resin made the boat, in effect, a one piece                        structure.. Polyester resin was used at first. Epoxy was used                        when it became available and is now the preferred bond. The                        British magazine Yachts and Yachting of February 8, 1963 told                        of the new boat and its enthusiastic reception at the London                        Boat Show. Those of us with plywood experience, who happened                        to be looking, knew that here was something new and that                        things would never be the same. The Marietta Yawl takes full                        advantage of the method and includes a number of innovations                        developed in connection with numerous other Taped Seam                      designs.
