Location: Gulf Coast USA Small working tugboat I'm posting these images for the hull of a small working tugboat I've begun to design. It's not designed for semi-planing speeds, this one is strictly a displacement speed hull with the specified 5-10 HP inboard diesel. Location: USA Maybe consider enclosing the prop totally inside a tube or at least a shroud.
Location: ft myers, fl I like it, it looks a lot like the 14ft Candu E_Z tug. The person shown is sitting and if he wants to stand in the house it's going to have to be taller, I can see that. Location: Gulf Coast USA Cute design, and almost the same as mine from outward appearance. Location: Flattop Islands I doubt this arrangement or hull form makes much sense for a truly useful working boat. The cabin and freeboard forward on this design makes it impossible to get on or off (or work over the bow) easily around a large portion of the boat.
We have a couple of very useful ting tugs here in Silva Bay, with relative mouse-power they do a great deal of work. When making potentially dangerous or financial decisions, always employ and consult appropriate professionals. In fact I really like that design quite a bit including the little cabin some nice canvas would really make this a great little picnic cruiser and camper on the islands.
If you want 12 knots you might want to look at the William Hand inspired efforts from Harry Brian, HandyBilly 21 or perhaps Rambler 21.
9 mph with 6hp is the speed given for the 29' Chassion power dory, I think it's in traditional craft to build and use, by Gardner. I spoke to Karl over at CMD boats and found out that his Launch Cruiser can accept a larger engine and acheive a cruise of about 12 knots. I have started researching the choices and the list is short, Yanmar, Westerbeke and Betamarine.
Almost the smallest possible inboard powerboat with real capability, Jigger was designed as tender to a 38’ liveaboard ketch. Designed to look related to the legendary Calkin’s Bartender, the Timbercoast is a slower and more economical solution to long days on the water. Power Pogy 6 Meter (19'6") Family Outboard Cruiser, could cruise a family of four along many coasts. So (1) what's the smallest reliable marine diesel on the market that could drive a fuel-efficient hull for cruising with two adults for a week or so at a time on the Chesapeake, the Carolinas, and other coastal waters, and (2) if you were going to do that, what design would you pick?

This is not a beginner's boat - the instructions are sparse, to put it politely, and are not at all user friendly. If I'm not mistaken, the host of the above link is a member of this forum, though I can't remember his screenname.
Try Gardner Wooden boats to build an use- There is a 24 ft'er in there design for low speed displacment.
Given the beach traffic on the bay bridge and the costs of buying a summer place, it's an appealing idea. You didn't say if an outboard is ruled out but if not, this would be a nice inexpensive rig to run, with a nice 4 stroke outboard in the well it would be quiet too. My earlier response was off the cuff, but it prompted me to revisit Stambaugh's design website. I've toyed with the idea of someting other than the transom bracketed outboard for my 23 footer (Compac 23 with a Sailmaster 8). I'm the guy referenced above that's building the Puffin 28--guess I felt my ears burning, being talked about. I had always liked Puffin, but after looking at Karl's designs, I also became interested in the Redwing 26, which is similar in appearance and construction, but I believe it's only offered with an outboard. An important and deciding factor was that Puff is a V-bottom, while the Redwings are flat bottom. And by the way, the speeds estimated on my website are from my own calculations, Karl really didn't make any claims except to guestimate in that same ballpark.
Karl said for putting around on the Chessy, or the ICW, that sort of stuff, the 26-foot 'Wing would be ideal. My intention was to build about the largest displacement-type hull I could (that I liked), that could be self-trailered. The original Puffin plans specified a beam of 8-6, which was instrumental in choosing the plan.
Anyway, I've always liked the old Elco-looking cruisers, and if Karl had that sweet little boat pictured above, I might have re-thought the whole thing. It should be easy to build in plywood, there's only a little bit of twist in the bottom panels, the rest of the hull is just simple bends.

I am not looking for a planing boat, something with character, economy, appropriate for the weather we have here in the PNW. That was back when Lake Union was a working lake and not given to the care and feeding of plastic badge wearing code zombies.

The first boat built has towed far larger vessels, played tender to motherships on the Shipyard Raid, and salvaged logs in the Flattop Islands.
With a deep keel directional stability is great and she is controllable with the small sails set. Speeds up to 7 knots are achieved with a 22 HP inboard diesel engine. Puffin also has about 750 pounds of internal ballast, and is conisiderably more boat all around, at about 6500 pounds displacement all up. I think with the engine I have and the prop I'm swinging (18") I can probably push the boat a bit beyond displacement speed, perhaps closer to nine knots, but that's not a sustainable cruising speed. But my primary use is in the Sea of Cortez, in Mexico, and it's considerably bigger water--the displacement V-bottom made more sense.
While the shallow draft may be useful on occasion, having the boat blow all over hell and having to constantly goose the throttle to get her to turn will be a constant pain. The trick seems to be that they planed easily at lower speeds but could only be driven so fast.
Overnight accommodations including galley, porta-pottie, double berth, and the smallest wood heating stove.  She can go to Alaska or across the bay.
To do this, I have modified the design so the transom is raised, to get rid of drag from the immersed one as designed.
I'm also looking at doing the Inland Passage, from the PNW up to Alaska, so in a word, the bigger boat was the easy choice.
A bit of a sticky wicket, and I asked him if I could build the older narrower design; he recommended I go for the newer wider version, which I did. First, Arizona (my state) has a ten foot limit on trailer boats, for an additional small fee. I chose to go with the outboard version, but Glen-L supplies a nice inboard version with the package, which might suit you.
But with a dodger and forward steering arrangement so it could be moved under power comfortably.
When he asked about the overwidth permit, they told him to save his money, nobody is out there measuring them.
