Updated APRIL 2014
The 1 SHEET WEDGE - It may look like some of my other wedge designs, but it differs in one important aspect; the basic hull is constructed primarily from one sheet of 1/4 inch plywood. At 8' x 2.5' x 1.25' and 30 pounds, it is an ultra simple 2 module design, with all straight lines, that is easy to build and operate by a single occupant. Less than $100 to build. The plans are FREE for the asking. (Oct. 2015)
COMPOSITE CRUISER - The primary purpose of this design was to build a small pram style boat that was ultra-lightweight, easy and inexpensive to build, was unsinkable, and used Coroplast plastic as the hull material. The "CC" is less than 30 pounds empty, and it fits in almost any vehicle for transport. The construction is simple, and only handyman tools are required to build it. The basic hull can be constructed in just a week. Plans are 28 pages with photos. Gets a lot of attention at the water. (Sept 2012)
CPB-2016 Is a 8' Coroplast Pram design that can be made in a day, fit in any car, and enjoyed for years. Especially designed for younger builders. The essence of this design lies in it's simplicity. Contrary to my previous Coroplast hulls, this one is all folds, and only a single cut. With a capacity of 220 pounds, almost anyone can enjoy the freedom of boating, many for the first time ! (April 2016)
DUET Utility Boat - A two module transportable that has the capacity to hold a small family. With built-in safety buoyancy and generous freeboard, it can provide great family fun. Easy to build and assemble at the water, it fits in all trucks and suv's, no trailer required. With a 500 pound capacity and ample storage, it also makes a great fishing boat or tender, easily handled by a single person. (May 2011)
EASY ONE is so named because of it's portability and set-up. Just a few simple steps from vehicle to water, then the easy part begins, safely cruising around your favorite water spot. This is the third generation of the "wedge" hull shape design, and it incorporates the previous builders suggestions for greater freeboard, dry storage and a sail rig option. Rugged yet lightweight, the Easy One makes a great utility boat, and with an added center module, can seat two in comfort. (December 2013)
The F.I.T. - This new wedge design is intended to satisfy the needs of many boaters. In it's basic single occupant form, 8' long, it will Fit In the Trunk of most autos. But, scale it up to 12' in length, and you can seat 3 comfortably. And, it can easily be converted into a simple day sailer. (Aug 2015)
FOAM BOAT - A single occupant, two module nesting design that is constructed of 1 inch polyfoam sheets, and reinforced with fiberglass cloth. The result is a 30 pound craft that is easy to transport and easy to paddle, and literally sits on top of the water. It can also be outfitted with a trolling motor. The hull design is unique for a boat this size, and utilizes my "skin on foam" construction process. No epoxy used ! Cost to build about $150. (Mar 2012)
Sept 04, 2015 - A 2 occupant sleeper version has just been added to the plans. It is 48 inches wide, and can support up to 500 pounds.
Micro CAMPER CRUISER is a scaled down MINI, and will sleep one comfortably, and seat two in tandem. Built lightweight, it can be transported by all trucks, vans, suv's and some hatch backs, and even a bicycle ! Stand up steady, it will make a great weekender for the sole hunter and fisherman, or woman. The cost to build is a modest $150, plus outfitting. Plenty of room to stow gear, and will travel 4 mph with a trolling motor. Will accept a small (2 hp) gas motor with transom modifications. (Aug 2015)
The MICRO Sail Boat is a departure in design. It is modular, 3 to be exact, but it's core is pure 3 Meter Sailboat. Ideally suited to the novice sailor, it features many options, from foot steering and boom-less sail, to a unique method of keeping the hull erect in heavy winds. Buoyancy chambers, both forward and aft, add to the safety aspect of the design. The concept is from the fertile mind of Craig Titmus, the originator of the Mini Camper Cruiser. Complete build plans are now available. (Aug 2015)
MINI CAMPER CRUISER - A real unique design by Craig Titmus of Tasmania, Australia. A boat with a capacity of 750 pounds on the water, converts to a 7 foot camper with accommodations for 2 adults. At 4' wide and 12' long it is stable and roomy. When folded in half it can fit in the bed of a pickup, or on a small flat bed trailer. Empty weight is about 130 pounds, plus gear, and it is easily fabricated with common shop tools. It's great for those weekend excursions. (Feb 2013)
MINI-CAT - This is a small twin-hull platform boat design, which was the Design Contest Winner for 2012. Comfortable for 2 people with gear, it can fit in any truck, van or suv. Builders options include a trolling motor, sun canopy and enclosed cooler. Stable, lightweight and easy to build. Simplicity at it's best. Ideal for fishing or just casual boating. Pontoons are 8' long and the deck is 4' wide. Bring your sleeping bag for an overnight ! Low in cost to build and operate. (May 2012)
MPDR - MODULAR PD RACER was designed for those that want the PDR experience, but prefer not to trailer it. This 3 module nesting version is true to the hull design criteria, while providing in vehicle transport. Approved by Shorty Routh, the PDR originator, the modular version has good interior room and can accept all PDR options, and it is class legal to race. The plans are FREE for the asking ! (Mar 2011)
POD-2 (Paddle On Demand) - This is a redesign of a very popular boat, expressly intended for the younger generation. It is easy to cut out and assemble, with straight sides and minimal curves. It has built-in safety buoyancy, and can be fitted with a small sail rig. At only 6' long and 30" wide, it folds in half for transport. A great project to get kids interested in boat construction. The plans are FREE for the asking. (Apr 2010)
POLLYWOG - This is one of the larger boats in the fleet. It can hold 2 adults and 2 children. Composed of two nesting modules, it can fit in all trucks and suv's, and some wagons. Adapts easily to a trolling motor or small outboard, and is ruggedly constructed of 1/4 inch plywood. The boat is ideally suited as a tender or launch, and makes a great fishing boat. Built-in seating and buoyancy chambers for safety. Also available is a sail rig set of plans designed specifically for the Pollywog, see below. (Feb 2009)
QUAD - A 4 module, 11 foot long, multi-purpose boat. Primarily designed as a 2 occupant canoe, it can also be used as a 3 module motorized skiff. All 4 modules nest to allow transport in any truck or suv. Wide and stable, yet smooth through the water, it is easy to build, and costs less than $150. Total empty weight is about 50 pounds. Ruggedly built, goes anywhere, and because it seats two, you won't be alone. (Sept 2013)
RIVER ROVER - This is a new boat, specifically designed for shallow water use, and can be constructed in different lengths and widths. The size you need is dependent on load and the number of occupants desired. Much like a pirogue, the longer hull provides for greater gear stowage, and smoother water transit. Easy to build, the two hull modules stack for travel. The 8 footer will fit in all SUV's, and some cars. The others require a truck or van for transport. (Aug 2015)
SIMPLE 8' PRAM - A wide and stable design, constructed of 1/4" plywood for strength and durability. The two modules fold on top of each other for a transport size of 4' long, 3' wide and 2' high. Capable of accommodating 2 adults, it makes a great hunting or fishing boat, to get into those hard to reach areas. Row, paddle or trolling motor powered. The plans are FREE for the asking. (Aug 2013)
SIMPLE 9 - A kayak like, 3 module portable boat. Constructed of lightweight plywood, it weighs only 40 pounds. It's 9 foot length and 30 inch beam give it good performance and stability in the water. It gets it name from what it is: Simple-Inexpensive-Multipurpose-Portable-Lightweight-Easy to build. An ideal starter boat for all ages. Fits in most cars and all trucks and suv's. The plans are FREE for the asking. (Nov 2010)
TOTER 2 - The updated version of the original Toter, can now seat 2 in tandem. This new design can also be fitted as a daysailer. All this in a size that fits in most cars, and all trucks and suv's. It also has built-in buoyancy, but still nests to store in less than 5 square feet of floor space. The 3 modules easily bolt together for fast assembly at the water, and the refined structure will provide years of service. (May 2010)
TOTER 2 SAIL - Completes the design cycle for this series. With a mainsail and a jib, the boat is capable of some fun sailing, and it can accommodate 2 occupants. All the attributes of the Toter 2 are enhanced with the sail rig, making the boat a true multi-tasker. With built-in safety buoyancy and a short, wide sail, the boat is safe for almost anyone to operate. The controls are always at hand, and easy to manage. All components fit in the center module for storage and transport. (June 2010)
U2-HULLZ , is a wedge design that takes it to the next level. The builder has the option to construct any of 5 defined hull sizes, or anything else of their choosing. The plans are complete, and provide the builder with many options which will personalize their boat. (Nov 2015)
ULTRA PRAM - The concept of Roland Moose, who needed a roomy and rugged fishing boat that had ample storage for gear and camping equipment. At a little over 8 feet long and 4 feet wide, with 18 inch sides, the design provides seating room for 2 adults and 2 children. An optional 3rd center module increases the capacity to carry 4 adults easily. All this, and it fits in the bed of most trucks, suv's and motor homes. The cost to build should be under $225. (Jan 2011)
WATER SCOOTER - This is a departure from the hull designs normally found on this site. It's a sit on, rather than a sit in hull shape, intended to be both practical and fun. At 3 feet wide and 8 feet long, when the 2 modules are disassembled and stacked, it can fit in all trucks, suv's and most hatchback cars. No trailer required. (Oct 2014)
WEDGE - This is a sturdy, roomy, 2 module utility boat with a unique hull shape. The wedge shape puts the buoyancy where the load is. It has good freeboard, and a 400 pound capacity. Ideal for sole hunters or fishermen with a lot of gear, and it is stand-up stable. Finished weight is only about 80 pounds. Powered by up to a 3 hp motor, or oars and paddles. It can also be converted into a very capable day sailer. (Oct 2011)
Just for your information, many of my boat designs can easily be modified to suite your particular application. As an example, the new F.I.T. plans depict larger versions to accommodate bigger people, or greater loads. And the MICRO CC plans define a wider hull, for those who don't want to go it alone.
All the plans are open to your imagination!
All plans can be purchased at http://www.duckworksbbs.com/plans/simpson/index.htm
Just a short note defining why my videos rarely include views of the entire boat, or anybody in them. Well, I almost always go out alone, and as a result, it is impossible to to get the whole scene, as my arms are just not long enough. However, the accompanying still photos should provide more than sufficient hull views to satisfy the need of most of the readers of this website. And, thank you for your continued support.

ASSEMBLY KNOB - It was only a matter of time before it was obvious that a quicker method of fastening the hull modules together was developed. This knob essentially takes the place of a wrench, and makes the installation of the hull assembly bolts a much easier process.

FOLDING MAST & BOOM - This is a clever way to get a 12 foot object into a 6 foot container. By using everyday available components, the mast and boom of most small sailboats can be made to fold in half for transport in your vehicle, not on it. Originally designed for the WEDGE, but applicable to all my sailboat designs. FREE to download.

FOLDING PLYWOOD SEAT - This design can be used on any of my boats that do not specify fixed seating. Easy to make, low in cost, about $15. Big enough for even the large person, the angle back can be adjusted to suite individual needs. Made of 1/2 inch plywood, can be painted to match your boat. Increase comfort by adding back and seat cushions. The plans are FREE.

PADDLE, Kayak Style - A long overdue addition to the plans page. I Built this basically from scrap materials, and it is rugged and easy to make. The double ended Paddle consists of a PVC pipe shaft, and reinforced 1/4 inch plywood paddles. It comes apart in 2 sections for easy storage. The total cost should be about $15 if you use leftover materials. FREE

This is the SIDE MOUNT BRACKET for attaching a Trolling Motor to the side of a hull. The primary purpose is to place the motor controls convenient to the operator's hand, without additional extensions. The bracket slips over the side of the hull, and bolts in place. The Trolling Motor is then easily secured to the mount. FREE ( Sept 2013)

SPONSONS - These are short, curved, air filled buoyancy cells on the side of a hull, imparting lateral stability in the water. They are designed to be easily added, and removed, from the boat. Certain narrow hull boats can benefit from the use of sponsons to increase load capacity as well as stabilizing the boat in rough water. The plans are intended to be universal, so the builder can modify them to suite the application. FREE

TAPE & GLUE PROCESS 2 - This is a method of boat assembly developed by this designer, to produce a simple, waterproof, non-toxic and secure method of sealing a hull assembly. It is applied after the basic hull is assembled. Many small boats up to 12 feet in length have been constructed using this process, as are all current designs on this website. FREE

TITEBOND III Ultimate Wood Glue - This is the first one-part, water clean up wood glue ever offered that is proven waterproof. It is non-toxic, solvent free, and cleans up with water. Much safer to use than other traditional waterproof glues. FDA Approved, it is ideal for both interior and exterior applications, and has longer assembly time. Specs below. FREE

It's always better when man's best friend enjoys the small boating experience in one of our designs.
Say Hello to Jake !
DUCKWORKS is the best place to look for boat building plans, supplies and articles.
A Boat Builders Best Friend.
It has been pointed out to me that the portable boats I design are helpful to the greening of our planet. Look at it this way: They all utilize primarily wood as a structural material, they all use TB3 Glue, which is FDA approved and biodegradable, and they all are recyclable, so when you are through with one it can readily be used by another, or cut up for kindling. Very little material is used in the construction, or use of these boats, that is not earth friendly. Even the recommended trolling motors are non-polluters.
So, join the hundreds that have bought one of my plans, and help the greening of our planet. Thank you.
Web Site Created September 2009
The boat plans listed here are the sole creation of the designer, Ken Simpson. It is his ongoing goal to design and develop small transportable boats that are easy and affordable to build. Although each design is unique, intended for a specific purpose, all share common assembly techniques. For instance, there are very few, if any, hull forms used in construction of these boats, as the bulkheads and transoms, combined with the mounted side panels, create the basic hull shape. The glue of choice for all construction is TiteBond III, a waterproof wood glue. No epoxy specified, or used. All seams are treated with layers of glass cloth tape impregnated with TiteBond III. This method was developed by the designer, and many boats of different sizes, up to 12 feet in length, have been successfully built using the process, now called the ' Tape & Glue Method of Assembly '.
That being said, the designer takes no responsibility, and cannot be held liable for any construction faults, personal injury, or any other result of the builders actions or materials, on or off the water. Also, the plans cannot be used for commercial purposes without the designers specific written permission.
