Dunlin 22

The Devlin Dunlin 22 began as a larger version of the pocket workhorse Godzilli 16. After Sam was finished, he expanded the boat into two configurations, both of which can provide you with all the work and play you could want in a boat this size. With a 60hp high thrust outboard and a very strong structure, the Dunlin can be used for a wide range of pursuits. With a cabin designed for plenty of headroom, a heating stove, a double berth, stowaway space for a port-potti, and a galley counter, it can also serve as a comfortable place to relax after the work is done. For the details and thought that went into this versatile workhorse, check out Sam’s design notes.


The Dunlin 22 Cruiser version is available in study and construction plans.

The Dunlin 22 Pilothouse version is also available in study and full construction plans.

Arctic Tern

ArcticTernShowMany designs go through several stages before they finally turn into a boat. Arctic Tern is one of those designs. The latest and final version is a logical extension of the Winter Wren. The lines are similar but the Arctic Tern’s are finer in both the entrance and exit. The sheer is strong but not overstated, with reasonable freeboard for the sea conditions she is likely to encounter. The cockpit is self-bailing and has sea lockers and lazarette for gear storage. A large bridge deck can accommodate either a small inboard auxiliary or a storage locker. Its amazing how much gear accumulates on a boat this size and the more stowage the better.

Down below there is a hanging locker and galley to starboard, settee (quarter berth) to port with full sitting headroom. Forward is a 76″ long double berth. The outline of the cabin allows seating both on the settee and double berth, and easy access to the galley. Double portlights port and starboard provide ventilation and good lighting below.

The Bermuda sloop rig offers an all inboard rig of 262 sq. ft. The rig has double reefs to reduce the generous sail plan in heavy weather. Arctic Tern is truly in the cruising size range and will make good passages from port to port in a variety of weather. The long keel and balanced helm make her a single-handers dream whether sailing alone or with crew.

River Crawler 22

A gentleman came into my shop a few years (Decades? Wow, time flies.) ago to discuss a small cruiser for protected waters. His requirements were fourfold: trailerability, shallow draft, a displacement hull, and a proper cruising cabin. Following the usual back and forth involved in a new boat design, we came up with the River Crawler.

This little cruising boat gives her skipper access to the little gems of anchorages that are off limits to larger boats. Drawing less than a foot, she would be equally comfortable in the Florida Keys or upper tributaries of the Columbia River. This shallow underbody is ideal for beaching and the keel protects the running gear. Generous access is given to the diesel sail drive via a large hinged hatch aft or this boat could conceivably be powered by an outboard in a well. An adequate self-draining cockpit leads to a cozy, yet comprehensive cabin. With a fully enclosed head to port and a galley to starboard, the skipper and mate have a lot of comfort for a boat only slightly over 22 feet. The helm and co-helm seats are afforded a great view through large windows. The bow has a large v berth, as indicated in the drawings. With an optional drop-in insert, the sleeping quarters can be made roomy enough for even the most acrobatic of sleepers. The River Crawler would be hard to beat for a couple who wanted to launch on a quiet creek on a Friday, explore for a couple days, then pull her out on the trailer ramp on Sunday. The humble River Crawler gives her skipper the full spectrum of gunkholing possibilities without the headaches that inevitably come with larger boats.

Unfortunately, the gentleman’s circumstances prevented the completion of this design. I’m hoping that somebody will come along and give the River Crawler the chance to come to life; she certainly deserves it. – Sam Devlin

Archimedes 22

The first seagoing steamboat that was designed and built for screw type propeller propulsion was the original S.S. Archimedes launched in 1839 and named in honor of the Greek scholar Archimedes. He is the man that is credited with the Archimedes principle which is used by boat designers almost daily to help measure the weight and mass of the boats we are creating. Perhaps a name with a provenance like this is a heavy burden to place on the stem of this little cruiser but then I rationalize, why not carry a decent name into battle? The enemy won’t always remember much about the battle but the name of a valiant foe always is.

Designed originally for a customer from Australia and intended to be used as the base of a steam engine and boiler for running about on Aussie waters, it wasn’t long into the design process that I started pondering what a wonderful platform she might be for electric power. Now mind you, I don’t really have an aversion to the idea of a steam boat in my boating dream life but when I start fitting the engine, the boiler, fuel and all into the boat, I quickly run out of space for myself and any crew that I might want to share the experience with. With our Archimedes 22, we have the space for all that and more, with room to either use a couple of repurposed antique wicker chairs for seating or if I am really slumming it, I will just sit on the side decks or the small stern transom seat at bulkhead #5 as shown in the construction view.


I truly do like the idea of the steam engine but I muse that many of you might not be so interested in firing the boiler, waiting for a head of steam to build, and the almost constant tweaking and oiling chores that a steamer involves. Imagine coming to the realization that you’ve been out in the boat with your sweetheart and nary given her a nod or a mention all day due to fooling with all the steam mechanisms. As many of you might conclude, that won’t be a proper way to spend a day for very long!

So let’s explore the idea of the electric drive. We looked at the options available to us and narrowed the list down to two options – either the Elco inboard electric engine, or the Torqueedo electric outboard. There is much more fooling around necessary for the Elco inboard as it is a conventional shaft type drive (very much like the steam engine) but makes for a neater and cleaner installation even with all the work spent on the installation. The Torqueedo drive is a no-brainer with the engine being mounted on the transom of the Archimedes, steering performed with the outboard and with a proper bank of deep cycle batteries in the belly of the little boat. But then the dilemma of why am I doing all this in the first place rears its ugly head. Yes, it is all about being on the water, but I keep thinking that the whimsy factor of boating is really almost as important to me as the water time. In fact, dreaming and scheming about being on the water is a truly fine thing to do with my short amount of idle time and that takes me full circle back to the steam engine. Even though it is complicated and involved, it easily takes the prize for the largest amount of dream whimsy factor and if I personally need to add another boat to my already bulging fleet, then I choose to live with the complication.

For you my friends, the plans of the boat can be used in any way you can rationalize your own dreaming and we offer them in all flavors with the tyro being able to build his or her steamboat or electric inboard launch, or as an electric or I suppose, even a gas outboard. The choice is yours. Construction is our normal Stitch-and-Glue method with hi-grade marine plywood used throughout along with epoxy resin and fiberglass and Dynel cloth sheathing for abrasion resistance. I am thinking of throwing away all logic and painting her a stunningly bright and shiny black and buff colored decks. Green bottom paint mixed custom for my color palette finishes her out. I am even thinking of hand carving the little scroll work shown on the bows, why not make her a proper launch! – Sam Devlin

Millie Hill 20

MillieHill20SternviewThe Millie Hill and her larger sister vessels are houseboats with an added layer of smart Devlin design. The 20 foot version is an affordable option with ultra efficient use of space to maximize the livability of the design. She can be moored in a small slip over the long term, or with the addition of a small outboard, she can be driven to interesting and beautiful places to create your own special getaway with all the comforts along for the ride. In the era of tiny houses, the Millie Hill offers the full experience of a home on the water.

Unsurprisingly, Sam has put a great deal of thought into this style of vessel. Read more about it in his design notes.

Curlew 20

Curlew20_3wayThe Curlew 20 is a new design done as a very simple and approachable powerboat capable of being the perfect companion to adventures on the water. Originally designed for Florida waters, I think she would fit in just about anywhere. Built as an open boat, a variety of other concepts and options can be worked into this relatively simple hull, all of them allowing the builder and boatman to tailor this vessel to suit their own needs and desires. She is on the narrow side being very similar to the Pangas of Mexico and the Caribbean that I am very familiar with. As a fishing boat on the bonefish flats, she really shines with a casting deck built into the forward area of the boat where you have plenty of room to keep your feet under you while standing up to cast into the clear waters.

Power can be up to a 90 horsepower outboard but keep in mind this hull does not need a lot of horsepower to be driven economically at a good clip over the water. There is a center console arrangement that helps keep the helmsman in an area of the boat with excellent visibility and control.

To understand the Curlew 20 in greater detail, read Sam’s design notes.

LichenBeauty2The goal with Lichen was to develop a smaller-sized sailboat (20 feet) able to comfortably cruise the backwaters and bays of the Northwest without excessive concern for draft. This vee-bottomed hull design is an answer to the challenge. The shallow draft can still yield a roomy comfortable interior suited for extended cruising. The Lichen features a retractable centerboard that draws 38″ down and just 17″ up, making shallow water navigation a snap. The shallow water draft combined with the medium light displacement (2500 lbs.) and moderately narrow beam, 7’8″, helps achieve another goal — trailerability.

On the water, Lichen has a very traditional look. The large barn door rudder and large open cockpit combined with her 237 sq. ft. gaff rig set the scene for outstanding versatility in a pleasing package. The mast is on a tabernacle, folding easily up or down, another plus when trailering.

Under sail Lichen is quite stable and sails well in a variety of wind and waves. It has always amazed me that these pram-bowed hulls sail as well as they do.

Interior accommodations include a large forward double berth, followed by opposing settee berth (centerline table attached to the centerboard trunk folding down to make even more bunk area.) To port is the galley, complete with ample workspace and storage, leaving the counter space uncluttered and visually pleasing. To starboard is a built-in wood stove serving as heater and dryer for wet gear. The portable head is under the companionway step. The most striking characteristic of the interior is the feeling of space and the visual freedom the large ports give you to view the beautiful scenery outside. — Sam Devlin

Dipper 17

The Dipper 17 was designed for the fisherman and pleasure cruiser that wants to get in and out of the weather and for the diehards that want to be out no matter what the weather. The boat is built using the WEST Epoxy System utilizing the latest technology with quality marine materials. The result is a boat with good looks, excellent performance, low maintenance, and the warmth and individuality of a custom wooden boat. All of these things make the Dipper an ideal boat for inland and coastal waters.


The wheelhouse is cozy, with room for a small galley, heating stove, refrigeration, double berth and storage. The aft cockpit is large, 64″ x 6’2″ with seating for three and stowage under the seats. The Dipper is easily trailered for fishing or pleasure cruising and at 2,460 lbs., it can be towed by almost any size vehicle. For power on the Dipper 17, we recommend an outboard in a motor well. A 10 hp Yamaha or a 15 hp Honda 4 cycle provide quiet, smooth power, and cruises Dipper at 7-8 knots speed with good range.

The Dipper 17 is available as study and full construction plans, and as a CNC cut kit.

Pelicano 23

Like the Pelicano 18, the larger Pelicano 23 comes in three distinct configurations. Bassboat, Center Console, and Shrimper.


In every case, the Pelicano 23 offers the unique combination of real world durability mixed with the classic Devlin style. Every configuration presents a very practical boat for a wide range of needs. The Bassboat and Shrimper both feature good berth space for overnight adventures; the shrimper adds a sheltered helm for operating in harsher conditions. There is ample dry storage below the deck. The Center Console version provides open space for wrestling those big fish and hauling bulky gear.

No matter your needs in a mid-sized speedboat, the Pelicano 23 delivers a strong, durable, and versatile answer.

For more information, read Sam’s design notes.
