Location: WA 10'-12' aluminum outboard skiff I'm looking for plans and CAD cutting files for a small runabout.
There are most likely very few plans or outline shape files for this size because of two market forces.
So one reason that smaller thin skinned skiffs aren't as likely to be available is that the people who design and build them aren't in the business of explaining to others how they make that product.
The other reason I think there are few plans available for this size is the lack of welder who want to build very thin hulls. So the next reason I believe there are few small skiffs offered is that the skill level needed to effectively weld thin alloy reduces the number of possible sales for this plans package. I'm assuming that a one-off skiff would be welded (?) but you may plan to rivet (?); in any event, there are few of ANY aluminum plans available let alone smaller and thinner scantling skiffs. Unfortunately, I didn't have access to NC cutting affordably but the day or so it took to cut the skiff with power tools wasn't much of a slow down considering the layout was generated by the software not a plate model.
Location: WA Kmorin, thanks~ I'm downloading Deftship even as I type this!
This extremely critical balance of variables becomes more and more exact as the weld size and parent metal get smaller.
While not [absolutely] true, this represents the widely held conventional wisdom on the subject. The real challenge is to keep the final boat hull's panels 'clean' ,fair, and smooth after they are welded.
I've attached photos of a 17' gunning dory that has a 3" hollow [flotation] bottom and hollow double wall 'ends' and only weighs 155lb.
Location: WA I posted my initial inquiry after seriously considering building exactly this boat. When making potentially dangerous or financial decisions, always employ and consult appropriate professionals.
Location: The deep blue sea Thanks to everyone that has responded to this post. I’ve corresponded with Renn Tolman regarding the Tolman Seabright hull and he is planning to run an inboard on his boat. Location: Australia FF - sorry, I meant why bother with the SB's complexity if using an outboard.
Tom - The shape you describe has (unless I misunderstand you) already been tried - and with much success.
I've been tinkering with a monohulled version along similar lines, which I've called the monomaran.
It might be possible to allow the box keel to have the plaining angle of attack , so the hull above would still be fairly level. The trim might be changed by venting the aft negative deadrise section with an OTS trim tab set. While a 10-1 L-B boat would be interesting , the Old Camper and Nicholson pre-war 50 ft launches ran 20K on 100HP, so its a proven concept.

Adding the light weight of todays materials and engines should allow the LB ratio to fatten and still be cheap to push.
But I'm wondering if the box keel actually was 75% of the displacement , if ONLY the LB ratio of the box keel would predominate? Lighter weight equals cheaper high speeds, so the weight of the engine and fuel would be the key in displacement , at 1500 lbs for the inboard diesel and 500 miles of fuel at perhaps 4 nmpg , it won't be too light. This would perhaps allow the boat to run aground harder , so might not be great for a designed beachable boat.
I think a flat planing surface on the keel might defeat the purpose of the combination as I see it. There are boats that carry all of the displacement in keels that operate fully submerged but they have to be cats or have fly by wire stabilization. Location: Australia Apologies to the original poster of this thread - we seem to have hijacked it somewhat, so I'll be relatively brief. FF - as Tom suggests, there's no point in building any planing traits into the keel section as it operates in a displacement mode, albeit at much higher speeds than the traditional 1.34 SL, as a result of its high LB.
Location: Australia In reality, the 'keel' section would probably carry greater draft than indicated. What other hull designs offer semi-displacement speeds at a low horsepower requirement, while at the same time offering a seaworthy, rough water capability? Here's a little one I've been designing in the evenings while building my Tolman Seabright Skiff during the days. At 6 inches of draft it has 9.5 inches of freeboard and its displacement is 500 pounds, 250 for the boat and 250 for a big person and some fuel and gear. From a hunter's perspective, I suspect there might be a fair amount of waveslap noise generated by the tunnel portions when slipping along at displacement speeds or when still in the water.
I like the idea of a tunnel-protected propellor as an alternative to a jet, and the low expense and user-friendly maintenance of the simple drive train.
Location: Knik, Alaska To be honest though, I hate putting outboards in a well. Noting that the most efficient planing hull possible is going to be the good ol' flat bottomed boat since it doesn't waste energy pushing water out to the sides in trade for a softer ride. Going in reverse in shallow rocky, gravel bar, or weedy conditions is always a pain, especially with a prop guard, but there isn't any perfect answer for the shallows. I figured that most people would prefer to save the cost of reverse gear and just use the oars to row backwards (or push off other things) until they could turn around.
Maybe when at rest, but I think I should build one and report on this first before guessing at it. The large scale plans show options such as center console, seats with side console, fish boxes and live bait wells, built-in gas tanks, light options etc. You can customize her: put the storage boxes and seats where you want them, keep her simple or install every accessories you want.

CANADA Up here in CANADA, we consider this about the lightest boat a man would handle. CANADA It could be built in .100 gauge, although I would prefer pulse mig for that thin. The basic hullform is rigid, with an inflatable collar that would ride with only the aft section just above the at speed WL. CANADA It occurs that such an elaborate bottom design would be better suited to fiberglass construction (and Im no fan of glass boats) for production. CANADA I agree an outboard in a well would be the simplest solution for power.The anti cavitation plate could be half of a gasketed sealing surface with motor down, and jacking vertically with a rack and pinion device or a foot operated lever as the old disappearing propeller boats had. CANADA Were getting into a regional discussion here.The guy with the nitro wouldnt last the day where I run,and I would be pulling weeds out of the foot all day where he does.
There is a slight difference in the sheer line but besides that, she is juts a longer version of the successful OB15.
A 15 hp outboard is sufficient to get her out of the hole with one person on board but a 25 hp is the ideal engine. I know you are right about the thicknesses; I may abandon this and build a slightly larger skiff but I'll explore Delftship a bit first.
The only difference being that the 'box keel' is replaced with parabolic or circular sections, that are more efficient in the displacement realm.
There are always going to be V8 jet sleds in the river and fountains with blown big blocks in the lakes. The longer waterline gives her more speed, a little bit more room and make her easier to launch from trailer.
The interior layout is typical of a fishing boat that will also be used for family outings. Third party names and products are for reference purposes only, all rights are reserved by these respective parties. Also, when I build the deck it wont have a step up in the bow, their is plenty of room for a 7.2v battery as it is.
I wish someone would build some of the versions with high displacement in a narrow canoe body keel and a low deadrise upper hull. The lower unit sealing issue could be solved with a rubber bellows surrounding the leg and sealed at bottom with aforementioned mating gaskets. My current boat already transitions at at no more than two degrees, so it seems very possible.
I dont think it will gain mass appeal as there is no greatest all around boat and it may be perceived as a gimmick.
