    Default Scaled up marsh cat

    Hello
    I'm fascinated by the sweet lines of the marsh cat.
    Is it possible to scale up/stretch the White marsh catboat? Is it possible to add a small cabin even on the boat built as per plans? Has it been already done in the past? Examples? Alternatively can you suggest me a similar design in the 16-18 range with a small cabin and still suitable for trailer boating? Cold molded ply on frame or eventually lapstrake.
    Thank you in advance
    Regards
    Gabriele

    What are the width limitations for trailered boats in Italy? That might determine which design you select. Catboats tend to be very wide for their length as well as heavy, so your tow vehicle will need to be powerful enough to safely pull whatever you build.

    There are lots of small catboats with minimal cabins, so you should be able to find a design you like. But if you really like the Marsh Cat you should be able to find plans for a cabin that you can modify to fit it.

    Thank You very much for the kind answer
    Maximum beam in Italy Is 2.55 meters, about 8.5 feet It would not be the biggest problem I think. Biggest problem would be weight, maximum for a comfortable trailer boat would be no more then 700 kilos, about 1540 lbs. I think s Whittolz 14'11" could be a good option even if I would prefer cold mold.

    Jay Benford has some nice-looking cruising catboats around 17' with a cabin:

    Scroll down to the bottom of the page to find a link to the small-ish cruising catboats.

    Might be worth a look.

    I am pretty sure Jay Benford, the designer, has a good reputation. I think the reason his boats aren't seen much is that his designs are older, and people have forgotten about them. I'm not sure if he has done any new designs lately. Maybe someone else here knows something more about him and will add a comment.

    I always wanted to build one of his small cabin boats.

    And what do You think about this design?
    https://www.duckworks.com/product-p/...lapwing-sp.htm
    It's the River lapwing 16' from British Selway Fisher.
    Another good contender would be the corvus from Whittolz. Even if I would prefer a more modern method of construction. For example strip planked or cold molded.
    Thank You in advance

    That Selway Fisher catboat looks like a beauty to me. It's not drawn with a cabin, though he would probably add one for you.

    Fenwick Williams of Maine had an excellent reputation for catboats. A full bow to complement the fat wide sterns to help helm balance etc. He drew an 18...



    This might be one strip planked...

    With articles on how they did it.

    Original plans are $125 from Woodenboat store: carvel on sawn and steamed frames. Damm right. Fully hairy arsed boatbuilding in your shed.

    https://www.woodenboatstore.com/prod...ams-18-catboat

    Your in Italy...an Italian designer Sciarelli drew one called Chirone that looks like it would suit. Might be bigger though.



    If you want ultra modern with electric inboard etc...the Fundy cat is a good boat. The genny would help in very light winds.




    The Fennick design is a classic thing from a man who pondered these things all his life. You could read what he thinks here...

    Thank you very much for the input! I have to confess that I like the fundy cat, even if some purists could disagree. What I don't like is the odd keel and the electric inboard. I think an outboard could be better. Has any of this boats been built? Are plans for sale? And are meant for fiberglass or wood? Can't understand from the site. I embrace the idea of a modern cat of that tipe.
    Fenwick 18 is a masterpiece, I think I will buy the plans just to dream about it. It is too big for what I intend to do. The same for Sciarrelli Chirone. Sciarrelli was a master in designing classic boats. I did not know he has designed a catboat. That boat was included by the designer in a list of his best designs. Plans for chirone are for sale in Italy for cheap, 30 euros here https://www.ilmare.com/prodotti/cat-...ostruzione.php
    Thank you very much for the book you recommended, I will buy it when I find.
    Here is an example of a catboat that can satisfy my needs, it's designed in Russia and one is being built
    http://www.amariner.net/sailing_yach...atboat_16.html
    What do you think about it?
    And what about the initial idea to build a scaled up marsh cat? I mean 10 %.
    Thank you very much

    I bought my Marshcat from the builder, a retired naval architect. He added a small cuddy, although probably not quite the size you are thinking of. Here are a few pictures to get a sense of how it looks, and the scale. I could lie in the covered foredeck/cabin of the cockpit and be completely covered (I am 6'2"). Not even much sitting headroom unless reclined or five years old. A boom tent would have covered the rest, although I never did. I think I still have his modified plans if you want a snapshot of just the cabin part. The pictures are from several years ago (and make me a bit sad/nostalgic).

    Wow, now that is a beauty. Looks like a great sailing boat too.
