    Piscataqua river gundalow

    Some time ago I was preparing an article for modelers who used to sail with RC sailboat models .This article was to make known the types of sailboats practically unknown in our country.
    Β On this occasion, I have practically discovered that, for example, Thames sailing barges still exist - even if they are few and increasingly costly to maintain.
    While collecting the materials, a friend lent me a book about Thames sailing barges. On the Internet I searched the site > modelbarge info < operated by Richard Chesney(sorely not functional now) . I managed to get more materials, and this eventually led me to build two models TSB¨(TSB Capricorn and TSB Gusty Cat - (Tomcat))
    Β In my archive, after many years, I pulled out a book that I received from a friend in New York >American ship models< by V.R.Grimwood > where there are many other interesting types of sailboats, but this time in the US.
    I started writing an article about really another rarity - Piscataqua River Gundalow. In this book there are other rarities, for example < Chesapeake Bay skipjack,Chesapeake Bay Bugeye, Scow schooner and more next vessels> but gundalow looked the most bizarre .. outside the shape that resembles a large surfboard (about 18 to 20 m long), so it has a Latin sail.
    More information about gundalow can be found on the web, in the above-mentioned book by V.R. Grimwood and also in the magazine> Ships in scale (11-12 1998).

    http://www.gundalow.org/wp-content/uploads/2015/05/Wooden_Bo...
    GUNDALOW - THE WORK HORSE OF THE RIVERS
    June 2008 (a short excerpt from the next article as info)
    Β The conditions in the shallow tidal basin area around Portsmouth, New Hampshire and Maine were a special case.Piscatqua River, and on its network of tributaries and the shallow Great Bay, which is seven miles upstream. The upstream towns were engaged in agriculture and manufacturing. Domestic and foreign imports arrived at Portsmouth on ships too large to navigate the Piscataqua River.. Portsmouth was their access to markets. The condition of roads at the time made them a last resort choice for transporting cargo, and not a choice at all in mud and snow seasons. Manufacturers and seasonal crop farmers needed more reliable transportation.
    The solution was a simple shallow draft vessel that could reach these growing river ports. A barge in its earliest configuration, the gundalow was poled over the shallows, rode the tide in and out of the Piscataqua, was rowed with long oars called sweeps, and later carried a large sail.The gundalows were simply built, many were little more than rafts. Some were 70 feet long and built to protect the cargo.They were not sea vessels. The sails where rigged on a short stout mast, about 12 feet above deck. The lateen sail was rigged much like the Dhows of the Red Sea and Middle East. The long boom, in some cases 70’, could easily be lowered for passing under bridges. The boom was hung on a chain from the top of the mast, about a quarter of its length from the boom’s forward end. Balanced there, the forward end was secured to the deck with block and tackle near the bow. The aft end of the boom, pivoted on the top of the mast was raised above deck at about 45 degrees.

    The Fanny M., launched from Adam’s Point in Durham, NH in 1886 by Captain Edward H. Adams, was the last gundalow to operate commercially in the area
    No gundalow has been preserved, but two replicas were built (1982 "Captain Edward H. Adams" and in 20011 - "Piscataqua")

    When I finished both models, I wondered what to do next ... so I started to build gundalow model.
    The model is approximately 1:24 scale, 90 cm long, 24 cm wide.

    first I drew up a plan from the book in the desired magnification. At first I thought about making a model from extruded PolyStyrene. Finally I used plywood and for the main part of the model I used a slightly modified way of building, which uses R. Chesney for its models of boats...the middle part of the model is such a box.
    Since gundalow has no keel, just a leeboard, I decided to use proven variants with a central keel (how it is at my TSB models)

    next steps
    I made a large yard (90cm) before. Its base is a pine beam 10x10mm reinforced at the bottom end with spruce beams 5x5 mm, grinded all the way to the conus,the yard is then fitted with 2x3 mm spruce strips at the lower end to prevent abrasion.
    I turned a short mast of beechwood.
    I already have a sail (Ripstop nylon)
    Next I glued the front and back keel, and finally the deck (3 mm poplar plywood)

    Yesterday I started to glue Styrofoam blocks to the hull, today I continued.my fingers are all black from polyurethane glue.I tried to use thin gloves made of thin polyethylene, but they were more of a hindrance to my work, and then everything was dirty with glue.Now I have to wait at least until tomorrow.

    Thanks Marky for info,I'll ask for the gloves in the drugstore.
    Today I grind roughly the hull and glued the ps into the gaps.Continuing perhaps tomorrow.
    Grinding polystyrene is an immortal experience .. preferably outdoors and in strong winds. I did it in the workshop and looked like a snowman ...

    Have read a few of the articles frpm Fisherman's Voice. Very interesting and informative. I was very interested in the Schooner Racing and Dory Fishing articles.

    Interesting article about the Gundalow too. Waiting to see your model under sail Tomas.

    No news at present..
    I am repeatedly grinding and puttying the hull of the model ..It seems to me endless work, it is still not the ideal state to paint

    The only thing not In the instructions, is the amount of patience needed.
    Its the secret ingredient for success.
    And looking back over this log, it appears that you have loads.
    Keep up the good work.

    I think that a coat of paint, thoroughly dried, before sanding can help in achieving a good finish. If working with wood, a coat of sealer, paint or varnish raises the grain on bare wood and that needs to be sanded, recoated, sanded, often several times before a finish can be achieved.

    I continue with grinding and puttying.
    I need a larger layer of putty due to the rough surface of GRP and fewer inaccuracies . Putty has yelowish color and my surfacer is pure white..maybe it would be good to spray the hull in a contrasting colour, then reuse the putty and grind.Used putty hardens very slowly, after puttying have to wait at least until the next day ...

    Is there any reason why you use putty as a filler? I would have thought that a resin based filler would be more satisfactory and setting harder makes a finish easier to achieve. I know what putty is like to use, it was all we had years ago and my main use for it was the final filler on a caulked seam on a carvel built boat. Of course, I do not know what is available easily in your country, but I would have thought there was something easier to use than putty. Sorry, perhaps I'm being too critical.

    OK,I was offered polyester putty in various modifications, I had to refuse. It smells very stiff when used, and I'm afraid I can't explain it to the people in our house.
    For puttying before lamination, I used acrylic sealant.
    I could use epoxy with a filler (fine wood sawdust) but it is too hard when used on soft ground.I used a special nitro putty to seal the hull of my second Thames sailing barge "Gusty Cat", but unfortunately it was not in the range of local drugstores... The putty I am using now is similar to Tamiya putty for plastic kits.

    Hi Nerys
    "Is there any reason why you use putty as a filler?"
    Bear in mind that that is a Google 'translation' from Tom's original Czech!
    You have to read between the lines a bit with Tom's postsπŸ˜‰
    Products like 'Plastic Putty' also confuse the issue a bit.

    BTW Nerys,
    If it's any consolation - I also used Revel Plastic Putty to fix the final small blemishes on my fish cutter. Quicker and not so much waste as mixing another batch of polyester filler.😊

    As you probably realised I was thinking of traditional linseed oil putty, especially as Tomas said that it took a day to harden.

    Hi,
    putty that I use is probably some synthetics, destined for synthetic colors, no linseed putty.
    I tried to spray the hull for another grinding, and I got quite angry. It was supposed to be reddish brown (RAL 3002), but there was some raspberry color in the spray.The original color should be "Indian Red", but I didn't find anything like that in RAL. I tried to compare the color of the hull "Piscataqua" on the net with the RAL sampler on the net. (due to similar color distortion on the monitor). I got RAL 3002.(see sample)..you can compare ..
    Then I saw another sampler - probably it should be RAL 3009 (3011)..

    Hi,
    I'll try to buy reddish-brown tomorrow.
    I grinded the hull, then sprayed the red paint, grinding, putty again, grinding and spraying now gray paint as primer.. I still need ammonia to soften the wooden beams designed as a low rail at the edge of the deck.
    I also prepare plywood for a new light fin for gundalow (about 850 grams)

    Hi,
    some next words about Piscataqua gundalow you can find here => http://www.gundalow.org/about-us/what-is-a-gundalow/

    Today I visited another store and chose a suitable shade of color for the model hull.
    When I came home, I found out that I bought the same color, but from another manufacturer. I got angry and finally tried to spray the RAL 3003 on the model on a gray background. It's not such a raspberry color as before , but a little darker .. ruby shade. Other colorΒ  I won't buy anymore. .. now I have red color for at least 5 models -
