    oh and one other thing

    i would go 5' wide and not 4'
    much more comfortable

    12' long is OK

    (4m x 1.5m)

    Found the engine I'm gonna use. No, I'm not going to use an outboard, don't like the outboard look on a tugboat. I would rather have an inboard so I could have the exshaust pipe behind the cabin like a reglular tug.

    Your draft will increase dramatically, your steering will become very sluggish in comparison to an outboard and you'll need a transmission, plus you can't easily remove it, like an outboard. Those engines are also very heavy for their output, very old technology being used there. Consider a Hatz portable instead if you must go diesel. You'll still need a transmission and have crappy steering but you will not have such a weight penalty.

    You can hide an outboard in a well and/or a box so it's out of sight.

    Thanks Paul, very nice little tug! I think thats a perfect match with Mike´s needs and skills. And I agree with the outboard.

    Regards

    Do I use regular window glass or plexiglass for the tug? does it really matter?
    thanks,

    Use Plexi it´s lighter and for a river it does not matter.

    I prefer glass, but not just any glass, laminated glass, just like the stuff they use in car windshields. Yep, it's heavier then acrylic or polycarbonate, but it's usually cheaper. More importantly, you can clean it and it doesn't "weather" like the plastics do. Plastics tend to scratch when you clean them and they discolor with age and UV exposure. Laminated glass (available at any glass shop) is available in a few different tints too.

    This proves there are tugboats smaller than mine. https://www.boatdesigns.com/products.asp?dept=525
    I like the stitch and glue construction idea. might use that on my boat. And I'll use window glass PAR.
    Don't like plexiglass that weathers and scratches easily.

    I want to be able to fish in my boat. Will that type of boat be good for holding a few salty fish? Maybe even a hammerhead or a bullshark....
    You know, since I'm going to live by the ocean, draft doesn't really matter...So I MIGHT go inboard. I don't really care about the tranny. I can get one.
    Thanks,

    Less than $2,300.00 in wood and F/B glass over where I live. Plus engine and drive and to save on that build in a used outboard.
