    Hello all,

    Haven't posted here before. I've searched your archives and know you've been over the flat vs v-hull in some detail. Still I have a few questions.

    I'm looking to build a boat (20 - 24') for the large lakes here in MN. I spend some time on leech, superior and michigan and would like to have my own craft that I can go out on those bodies with. I've got a 14' aluminum now that bobs in the waves to much.

    I don't want to spend a long time building or a lot of money on this project. Its my first project so I'm not looking for something tremendously complicated. I was considering a dory because I have the impression they are very seaworthy in case the winds kick up. I know they pound, but based on my experience you have to go to a pretty deep v in order to really fix that. Shallow V's will pound too. Deep V's draw more than i would like this boat to.

    Someday I'd like to build a bigger displacement hulled boat, but for now I'd like something with a little speed, some room to fish, and stable to cast from.

    Thanks all for any replies.

    if you have the freeboard, you might try adding ballast to the boat you have. any light boat is gonna bob on the waves.

    Thanks Tohbi,

    Truth is I've caught the bug to build a boat. In doing so I want to build one that gives me some additional room, speed and access to larger waters.

    I was thinking dory because I really like the lines of a dory and have read t hey are sturdy, capable boats.

    Dories are very seaworthy boats if they are well designed. They are also easy to build. What kind of propulsion will it have?

    The propulsion will be outboard. probably with a well with a reverse chine on the stern. Size of the outboard will depend upon funding at that point. Would like to put a 50 hp or so on the boat.

    I've looked at serveral designs. Spira's Key Largo, Glen-L's Hunky Dory and Bateau's OD 18. Some use stitch and glue, others use ply over frame. The latter seems to me would be more sturdy.

    Thanks

    50 hp on a dory? is this a typo?

    If you want more speed, have you considered a Carolina style skiff? They carry the power you are looking at. Flat bottom boats have a harsh ride though.

    no much of a typo. for a 20'+ boat I see many designers ok with a 40hp.

    what design would others recommend for a smoother ride, ease of construction and decent draft (< 1')?

    Thanks

    How about a downeaster style. Lobster boats have a pretty good speed and seakeeping abilities. I've designed a few of them. They are semidisplacement hulls.

    Donwneast fan.

    Downeast hulls are great. A nice entry forward with good flare helps keep the boat dry. The flatter run aft gives good lift to get the boat up on step.
    My only question is if it is an easy hull to build, as mentioned in the first post?

    admittedly, what i know about dorys is what i've read but my understanding is that they are displacement craft, designed to operate with very low hp and carry heavy loads. they aren't that shallow draft and their transoms can't carry a heavy outboard, hence the well in the middle of the boat.

    they are, however, seaworthy and easy to build. another boat that is easy-build and high performance is the sharpie. "the sharpie book" by ruel parker [?] is a good read about this design. this hull has the advantage of very shallow draft. i know that construction is so straight-forward that people used to build them right on the banks of the chesapeake.

    glen-l offers plans of a very attractive sharpie of 20+ feet.

    A couple of months ago I sold a downeaster style design to someone who has neve built a boat. It was lofted, so the patterns were full size. He has all the parts ready to plank. With strip planking framless construction you don't need high specialized skills. However a plywood hull would be cheaper and faster.

    Good afternoon,

    Gonzo, I love the looks of a lobster boat and like I wrote in my first post, I was thinking about someday building a displacement craft. I love the lines of lobster boats.
    since my project won't start for another year at least I may just skip the dory and build what I really want instead.
    I've looked at Glen-l's double eagle and Bateau's Novi 23 and Down Easter Cruiser 23. All appear very nice. Any other plans you can point me to?

    Thanks again

    You might want to take a look at the Tolman Skiffs. V hull, 12 degree transom deadrise, plywood FG construction, 18 to 22 feet,
    cuddy cabin and console interior options.
