    ben2go Boat Builder Wanna Be

    Please be kind.I am new to this.I have been researching homebuilt boating and plans.Our lakes are quickly drying up in upstate,SC.Many fishing and ski boats have been running a ground at speed due to unusual currents building up sand bars.I don't need a fast boat or a ski boat.I need a shallow draft recreational boat with the ability to camp 2 adults and 4 kids for a weekend and 2 adults for a week.Here is what I came up with.There's a spec sheet below.This is also my very first time using any design software.I used Google SketchUp.


    Flat Water 19

    Hull
    Length Over All(LOA) 19'4"
    Height Over All(HOA) 6'6"
    Width Over All(WOA) 6'

    Cabin
    Length 14'8" including forward birth
    Length 11'4" not including forward birth
    Height 6' cabin walls can be built taller
    Sleeps 4/6 with a canvas cabin encloser on aft deck
    Aft deck can be made self baling for fishing.

    Draft N/A
    Weight N/A
    Water Line N/A
    Displacement N/A

    Estimated Power 10-30HP out board

    Useage: Day or weekend cruises with the family on
    shallow lakes and rivers.Week long crusies with
    the spouse.Shorten cabin and use as a fishing boat.

    Building material choosen/off the shelf lumber with
    fiberglass and epoxy re-enforcement/hull seathed in
    fiberglass cloth/interior and exterior coated with
    epoxy for water resistance


    These are my ideas and sure to change.Opinions and
    advice welcomed.I chose a flat bottom for room and
    Our dring up lakes and rivers.We have problems with
    bass and ski boats running a ground.I can pull the
    motor up and pole my way through the shallows.

    Well, other then the aesthetic considerations she'll likely float, though I'd make the beam (width) 8' for increased stability and decreased draft, especially seeing how top heavy she is. With the modest power you're suggested, top speed will be about 6.5 MPH. 15 to 20 HP will get it done, with some reserve left over to punch through chop.

    Of course with that much structure exposed to contrary winds, you'll not want to be out when it's rough, plus the flat bottom scow shape will pound much if driven hard into chop.

    I'd also recommend you provide some "crown" to the foredeck area so it can shed water (much like what you've done with the cabintop). Also consider some sort of rub rail, so you can meet docks, pilings etc. without scrapping the whole of the vertical flanks across them.

    If building in plywood, 1/2" bottom and 3/8" sides will keep her light (important). If you expect much walking around on the foredeck, then make this 1/2", ditto the cabin roof, but 3/8" will work if you don't plan on being up there very often.

    Taped seams over well placed bulkheads and furniture would be my recommendation for structural elements. You could build it conventionally over frames, though it will add considerably to her weight. These frames could be on 16" - 18" centers and 1x3's with 3/8" plywood gussets (both sides) at the corners. Don't be tempted to "over build" thinking it'll be stronger, it probably will not be and the weight penalty is something you pay for, each time you fill the gas tank or get into shallow water.

    The transom should be two layers of 3/4" plywood or better if 3 layers of 1/2", especially if you later plan to add more power (1.5" is standard for the outboard clamps).

    Most folks like to be outside when on the water. The aft deck is going to get crowded with 4, especially if you add some chairs. Think you want some more room back there. Nice "out of the box" concept.

    Hi Ben,

    I like where you are going with your solution. Interesting thinking.

    A couple of years ago, I did the design shown below as more or less, a tongue in cheek tribute to Popular Mechanics Magazine and it ran on Duckworks Boatbuilders Magazine www.duckworksmagazine.com A casual glance would show quite a few similarities to your design except my boat has a medium vee hull up front that transitions to a flat run aft and the cabin structure looks like a distorted Art Deco house of sorts.

    I was just trying to have a little fun and then something strange happened... I started to get serious queries from the far-flung readers of Duckworks. with most of them asking if a smaller version could be done for the mid-sized American pick-up truck models.

    It never went any further than that, but it was sure fun producing the concept and getting mail from all over the place. Here's the direct link to the article. http://www.duckworksmagazine.com/06/designs/flippin/index.htm

    more research have been done. for example, how about the seakeeping of the ship ? and strength of the stucture of the house

    nice idea,

    Ben2go,

    I live in the Fiji islands and have worked on many ships here. I like the design but I think you would be better off if you had more of a rounded bow(if your looking to get the most room on-board) or maybe have it taper down into a medium deep vee then as you go aft it flattens out to be a flat bottom hull as Chris said his design was. I would recommend at least a 25-40hp outboard if you are going to keep the flat head bow. The flat front will be like trying to push a door through the water. I've seen in rough water wooden boats of this similar design just get hammered, and often they call in asking for a tow. Maybe you should look into a catamaran style as another option?

    this is just what i think,

    Jordan

    I plan to do plywood bulk heads and use built in furniture to help keep the hull strong.I had considered going 8' wide and 24' long for more beam and length for a larger rear deck.My plans had changed to bow the front deck same as the roof.My main objective is a shallow draft for protected waters, low power requirements, and fuel usage.I don't need speed.I just wanna site see,fish and enjoy recreational areas with the family.If our lakes and rivers weren't drying up,I'd go for a V hull type full cabin cruiser.Here's a better side view that shows the slope of the bow better.I am planning to do an interior lay out and see how I can arrange everything to strengthen the hull.I'm trying to gather rough dimensions for everything.I just have to remember light and trailer able.It would be nice to do the Bateau.It's a nice design.When I do my next boat,I wanna be able to cruise the ICWs and Florida keys.If gas is still affordable.I looked into hoover craft and almost built one.I need more than they can handle.Not saying they're not loads of fun.I know they are.Thanks for the comments and suggestions.I will incorporate some of the suggestions mentioned here.Hope to report back soon with more.
