    hey guys :) new here but been playing around with a home made boat ( that ive only really used out the back of my old place in a swampish area.. using a long stick to push me along.. went well though :D ) ill try find a pic 2morro

    but was wanting to build another, with a bit more thought about the design.
    still faily small ( something around 1.8 to 2.5m )
    light without weakening it :)
    and motorized, thinking a trolling motor and small petrol ( something cheap, to cruze along with )

    plan is... a adventure :) ( with testing before hand and will take bit to get gear )
    travel up the river and relax, no real race, just a few days or so..

    so will need swag/eski :p
    but can work that out arfter.

    last one was like 1800mm x 900mm x 300mm ( LxWxH )
    needs to be bigger then that one :)

    thinking about 1.2m to 1.4m wide?
    and about 2.2m long ?

    about how thick plywood should i use? ( as well as a decent frame keep it sturdy ? )
    how do i work out how much it will hold ( weight wise )
    im 85kg... average batterys like 15kg? ( x 2 ) fuel food ect? haha :)


    am i crazy? yeah proably

    was just playing around a bit,
    this is my last boat i built..
    [​IMG]

    was thinking of something like ...

    [​IMG]
    [​IMG]

    the motor will be smaller, and thinking a small petrol / electric trolling motor.
    battery's will be under the seat with a semi decent sized tank
    ( petrol will be backup motor/if need to get somewhere faster )
    eski will be up the front, as well as other gear.. to keep weight more even

    just so u all know river most likley be going down/up most likley this one
    [​IMG]
    isnt very big, but beauitful place :) ( for me anyway )

    sorry about pic size D: not sure how to change it,
    and haha yeah mr efficiency, ill try not ;)

    was just glancing over some other builds
    and looking at http://www.boatdesign.net/forums/boat-design/starting-chugger-42964.html
    the chugger design might be a nice idea thoughts?
    would give me cover ect, just make it heavyier?

    thought was the front half ( ish ) would be chuggerish..
    but then would take away room for tieing up/fishing? though would help, more space ect :)

    Some more text ect... haha last one for now..
    http://i871.photobucket.com/albums/ab280/Liighthead/9d0aa047.jpg
    something like that, double door's so can open it up,
    only like 2 to 2.4m long.. so not much longer then a normal one, just more complex ...
    thoughts on it? normal punt or sir chug? haha

    Light:

    This is similar to what I use, and probably easier to build a copy:

    http://tufox.com/hobie/index.html

    Self bailing, much lighter and easy to handle, easy to get on/off, instantly hold position by standing up/sitting in shallows, can be carried/launched anywhere, etc.

    Here are some inflatable type that have good storage room behind the seat and can be adapted to a motor:

    Hope this helps

    Way cool, river adventures are great. Looks like 1/2" (12mm) ply from your picture. If weight is a consideration, and I would think it would for a bunch of reasons, I suggest you consider 1/4" (6mm) instead.

    And it might be the lighting in the photo, but some of that looks pressure treated, if so think about not going that way next time. Too much weight with no real benefit.

    Maybe stretch it to the length of a full sheet of ply, get the sides, bow and transom out of another. In 1/4" would probably weigh the same as whats pictured. Maybe make the forward deck big enough for a little pop up tent. There is nothing more versatile than a flat space.

    Ahh nice those pontoons would be a great setup, just have to sit down ;)
    But yeah ur right easy to move lighter ect
    I'll have a look into it a bit.. :)

    Haha yeah last boat was 90% scraps wasn't to bad dragging it thru grass/mud bout 150 meters

    The sides where 19mm and most the weight lol

    Was thinking 14mm the whole thing?
    Maybe roof seats ect 6mm, but rather keep the outside 14mm :)
    And proably a dar pine semi frame. ? Haha

    Or... Pontoons 0.0
    Just doesnt have the little cover a chug could have ( tarp over the back half )
    And Easyer fishing in boat then pontoons? Tho doable :) and more moveable? Lol

    Yeah will be nice :)
    If I can work out which one build it and go away for a few days :)

    Leaning towards the chug. It's just heavier then the other to, but has shelter?
    Or a normal punt with a canopy ?

    Illd think it'll be Easyer to do stuff in the chug tho, and can set It up better? Lol idk
    All would work, and do their job well :) just chosing is the hard part haha

    You'd be better to go longer and narrower than short and wide, will go much better. No need to build like a brick outhouse for the sedate usage and quiet waters you have in mind, either.

    yeah was thinking about it...
    99% sure can get a sheet of ply thats 2.4m long make it easyer ?
    not sure how wide can always make it skinnier

    was thinking like 2.4m long by 1.2m wide? thoughts
    not sure how tall, guessing around 1m, so can kinder see out over the top, but still decent room inside ?
    1 thing it needs, is to be able to fish out of it, decently :p

    or just a small punt, and go from their? lol
    thinking the chug would be a nice boat, but a punt easier to fish out of ect, chug.. well more of a Cruising boat

    the punt, just fishing here and their...
    the chug, longer distance, camping trips ect

    8 feet is too small, I'd say anything under 10 feet would be too small if you take someone else along, unless you're on extremely friendly terms ! The topsides don't need to be high at all, 15" would be enough imo.

    Welcome, Liighthead.

    I built something quite similar many years ago. It was 10 feet(305cm) long and 4 feet(121cm) wide 1 foot(30cm) high, laid out just like your drawing. It was framed in 2 x 2 inch(51mm by 51mm) lumber and covered in 1/4 inch(6mm) plywood with 10 oz. fiberglass cloth. Transom was 1.5 inch(38mm) thick and raised to 15(38cm) inches. It held 2 adults okay as long as they stayed seated.
