 The Clinker Plywood method of boat building is not considered as easy as the Stitch & Tape method. Perhaps that's true but we don't necessarily agree. It takes a bit more time as you need to set up a build frame and each set of planks needs to be fitted and the glue cured before the next set is started but, that doesn't make it difficult. Some Stitch & Tape designs can be difficult to pull together when tightening the stitches and awkward when trying to get them square and level. At least when building with the Clinker Plywood method, only one set of planks needs to be dealt with at one time and the rest of the boat should be held firm by the build frame. Most of the Clinker Plywood method has been touched on already but the basic build is to set up a build frame first. This will probably involve a mould(s), stem, transom and keel or keel plank. Then the planks are added in pairs to this framework being glued to the stem and transom plus the previous plank or keel/keel plank in the case of the first planks. Once the planking is done, it is released from the build frame with the stem and transom fixed and set upright for fitting out - adding the seats (thwarts) and trim before preparation for paint and/or varnish.
Larger versions of some of the designs below were finished last year and will be added to the fleet portfolio throughout 2017.


Winchelsea 2.2  Rowing/Motor/Sailing Dinghy

    

    
 Loa 2.26m (7’ – 6”)
Beam 1.19m (3’ – 11”)
Draft 0.127m (0’ – 5”)
Dry Weight 22.5kgs (50lbs)
The Winchelsea 2.2 is available as a kit and as DIY plans. It is a little smaller than the Winchelsea 8 and the planks can be cut from a standard sheet of 2.44m x 1.22m plywood - no scarfing required. It is different from its larger sister as it does not have a long keel which is replaced by a flat keel plank onto which a length of timber and a skeg are fitted. The open edge of the stem is capped with thin strips of wood that are carefully bent round to join at the keel.
The flat keel plank makes for an easier build but it is still built in the same way - over a mould. However, it could be built using stitch & tape if you don’t mind the stitch holes. If you’re painting your hull inside and out, this is not a problem but, if you want to varnish your hull then don’t use it.
 
Basic Materials Required
Plywood – 2 sheets of 6mm exterior or marine grade for the hull, 1 sheet of 9mm or 12mm ply for the mould, transom and the
seats, for the knees and breast hook.
Solid timber lengths for the sheer trim 2.4m or longer.
(The mould can be made from 12mm chipboard or MDF as a possibly cheaper option).

NEW!! Winchelsea Garden Boat/Planter DIY Plans
or a kids boat rocker

 
A 4' (ish) mini version of the Winchelsea design.
We have built quite a few of these and the uses for this little boat are many - a garden ornament, planter, indoor feature, book shelf unit, wedding or exhibition centrepiece, a rocking boat for kids, toy box, pond decoration and this is just what we've built so far have been used for.
Now, we have drawn up full size patterns and step by step instructions package so that you can build your own.
The plans show how to make it as a garden ornament or planter, as above, which could also be displayed indoors.
The plans also give details and patterns of how to add rockers which turn it into a rocking boat for the younger sailors to enjoy. You can add a little pair of oars too.
The step by step instruction manual and a total of 14 A3 sheets of Full Size Patterns for every part of the boat which details how to build this great little boat from 1/2 a sheet of 4mm and 1/2 a sheet of 6mm ply and a length of stripwood.
Although the plans give the patterns for the breasthook, knees and thwarts in plywood, solid wood could be used to make this look even better.
Full size patterns for the rockers and their supports is also given.
It is built in the same way as the full size version so it could be useful as a trial build before you try a full size boat of this type of build.
 
As with our full size boats, our free help while you build service is available.


The plans package of full size patterns and build instructions is
£35.00 inc. UK postage
 



If you would like one of these built for you, prices start at £150. Contact us for details.

Winchelsea 8 Rowing/Motor/Sailing Dinghy
 

Loa 2.44m (8’ – 0”)
Beam 1.168m (3’ – 10”)
Draft 0.152m (0’ – 6”)
Dry Weight 30kgs (65lbs) Rowing Version

The "WINCHELSEA" rowing/sailing dinghy. 8' - 0" x 3' - 10" and a dry weight of around 90lbs (41kgs). The excellent examples are some from our builders. These are the original plans for this boat as I originally designed it - a multi chine clinker style dinghy that has a variety of uses. It can be rowed, sailed or motored and is a sturdy little vessel. Plans are now available as a rowing/motor version or a sailing version and both options are in the plans. The size of this boat means you can't get the length of the planks from a single sheet of plywood so you have to "scarf" a small piece to 4 of the 6 planks. Full details in the plans. It is also not built in the "Stitch & Tape" method of the previous two designs but is built over temporary moulds. Not as simple perhaps but didn't pose too many problems for the test builders.

Basic Materials Required
2 sheets of 6mm exterior or marine grade for the hull, 1 sheet of 12mm ply for the moulds and keel/centre frame, plus half a sheet of 9mm or 12mm for the seats, knees and breast hook, or solid timber to fit,
The moulds can be made from 12mm chipboard or MDF
as a possibly cheaper option. Then the keel can be made up from a smaller sheet of 12mm ply although still 2.4m in length.

Winchelsea 10  Rowing/Motor/Sailing Dinghy

  
  
Loa 3.04m (10’ – 0”)
Beam 1.37m (4’ – 6”)
Draft 0.178m (0’ – 7”)
Apprx. Dry Weight 30kgs (130lbs) Rowing Version
 
 
These plans are for the "WINCHELSEA 10". The pictures above show two great examples from first time builders. A very similar looking larger version of her 8’ sister, continuing with the clinker style hull, 6 planks per side, multi-purpose Rowing/Motor or Sailing dinghy that can be used as a tender to a yacht or larger vessel or for a day of fun on the local water. She is 10’ - 0" in length, 4’ - 6" beam and designed to be as light as possible for her size and construction. Although she could be carried on the roof rack of a large car, she is far more suited to a small trailer. She will also take a small lightweight outboard 2hp - 3.5hp for motoring up and down the local river, canal, harbour or around the local lake. Electric outboards are an option with this boat too. The plans detail the transom outboard pad to add strength. Built in buoyancy bags can be added by enclosing the seats or fitting inflatable buoyancy bags. The plans are available for a rowing/motor or full sailing version or you could build to rowing/motor standard now and add the sail rig later. .
 
Basic Materials Required
3 sheets of 6mm exterior or marine grade for the hull, 1 1/2 sheets of 12mm ply for the moulds and keel/centre frame (unless using 18mm) and transom, plus half a sheet of 9mm or 12mm for the seats, knees and breast hook, or solid timber to fit

Winchelsea 12  Rowing/Motor Dinghy

  
  
Loa 3.81m (12’ – 6”)
Beam 1.52m (5’ – 0”)
Draft 0.177m (0’ – 7”)
Dry Weight 64kgs (140lbs)
 
These plans are for the "WINCHELSEA 12". Still very similar looking larger version of her 8’ sister, continuing with the clinker style hull, 6 planks per side, multi-purpose Rowing/Motor or Sailing dinghy that can be used as a tender to a yacht or larger vessel or for a day of fun on the local water.
She is 12’ - 6" in length, 5’ - 0" beam with an approximate dry weight of around 140lbs (64kgs). Not really suitable to be carried on a roof rack, she is easily trailed and launched. She will also take an outboard 2.5hp - 3.5hp for motoring up and down the local river, canal, harbour or around the local lake. Electric outboards are an option with this boat too. The plans detail the transom outboard pad to add strength. Built in buoyancy can be added by enclosing the seats or fit inflatable buoyancy bags. The plans are available for a rowing/motor version. The plans include the details on how to adapt a rig that would suit this boat and a Mirror dinghy ihas been adapted to this hull.
 
Basic Materials Required
6 x sheets of 6mm exterior or marine grade for the hull, 1 1/2 sheets of 12mm ply for the moulds and transom, plus a sheet of 9mm or 12mm for the seats, knees and breast hook, or solid timber to fit, (The moulds will become the seat supports. The Transom can be made up from the waste 6mm plywood from planks etc.).

ROTHER 2.5- Mini Gaffer  Sailing Dinghy


    
LOD 2.49m (8’ – 2”)
Beam 1.27m (4’ – 2”)
Draft (With average load) 0.17m (0’ – 6.5”)
Dry Weight (apprx) 34kg (75lbs)
Max. Load 250kg (550lbs)
Sail Area 3.53sq.m (38sq.ft)
Although this boat is still aimed at the first time DIY builder, the rig requires a bit more thought. She is built in the same way as the standard boat over a simple build frame but she has certain refinements such as a rounded stem. This design is too large for the planks to be got from one sheet of standard plywood and scarfing is necessary, however, the plans describe a simple method of doing this. There are two options for this boat, but both are a sailing dinghy. She could be built as a rowing boat but, as the bowsprit and deeper keel would be a bit out of place, you could build the dagger board option and not fit any of the sail rig. There is one rig option with either the standard triple keel or a dagger board. It is also possible to build this boat using the “stitch & tape” method of construction and plans can be arranged for this.
(She will be available as 12’ – 6”  3.8m by Summer 2017).
She can be fitted with an outboard motor of between 1.5 and 3hp. Electric outboard motors are also an option and one I prefer. A tough little boat that can be trailed to the water and then easily launched and recovered but the triple keel version should not be beached very often - if at all. She is primarily intended as a deep water boat having been designed for Rutland Water and the dagger board version should be used if she will often be taking the ground - board up first of course.
The plans manual gives details of both underwater configurations, the rig details and added refinements. We suggest with this design that you have a bit of experience with building a rig or sails and sailing before you attempt this boat but, as always, we are on hand to help you via email or phone if you need it. The hull is the same build as the standard boat but the rig is a little more complicated than a single sail.
 
Basic Materials Required
4 sheets of 6mm exterior or marine grade for the hull, transom, keel, stem piece and bilge keels. Half a sheet of 12mm for the seats, knees and breast hook, or solid timber to fit. The mould can be made from 12mm chipboard or MDF as a possibly cheaper option. The transom, keel and stem piece can be made up from 12mm ply or solid wood (Stem Only).

 ROTHER 2.3  Rowing/Motor/Sailing Dinghy

 
Loa 2.26m (7’ – 5”)
Beam 1.19m (3’ – 11”)
Draft 0.115m (0’ – 4.5”)
Dry Weight 18kgs (40lbs)
 
This dinghy was designed as a simple tender for a yacht. It's size was dictated by deck stowage and it had to be lightweight but sturdy and traditional looking. It has turned out to be a minor success as two were built in Greece before we managed to get the prototype finished and tested where it performed as well as the reports we'd had from Greece.
It has two options for sailing but the dagger board option works best.
Built, surprisingly quickly, using the clinker plywood method over a simple mould frame and then released to fit out with seats and trim etc.
This design is only available as the full complete plans package with drawings, step by step instructions and full size patterns.
We have also been asked to do something different with this design. More on that next year.

Romney 2.2  Rowing/Motor/Sailing Dinghy

   
    
LOD 2.28m (7’ – 6”)
Beam 1.19m (3’ – 11”)
Draft (With average load) 0.17m (0’ – 6.5”)
Dry Weight (apprx) 30kg (65lbs)
Max. Load 225kg (500lbs)
The ROMNEY 2.2 is a clinker ply rowing/sailing tender with 7 planks per side. The design is forgiving of minor errors as we show in the plans but accuracy is, as with any DIY build, still important. No scarfing is necessary with this boat. She has a single sail option although the initial plans were for the rowing version but the sailing version is now available. This too is a tough little boat that can be carried on a roof rack of the average family saloon or trailed. Generally in clinker designs, the broadest planks are the garboards and the next plank out from it, the sheer or top plank being perhaps three quarters of their width and the narrowest planks taking up the curve of the hull. In this boat however, the broadest plank is the sheer plank because we felt this helped to make it easier to build.
It also made her a little more pleasing to the eye – in our opinion.
This little boat makes a great tender for a larger boat and will tow nicely too.
 
Basic Materials Required
2 sheets of 6mm exterior or marine grade for the hull, keel and transom for the rowing version. 1 sheet of 12mm ply for the mould, knees and breast hook, or solid timber to fit, (The mould can be made from 12mm chipboard or MDF if preferred. The keel can be made up from a smaller sheet of 12mm ply although still 2.4m in length). This boat could be built in 4mm plywood planking for a lightweight boat for very light use.

Watch Bell Pram  Rowing/Motor/Sailing Dinghy


  
Length - 7' - 8" (2.34m)
Width - 4' - 0" (1.22m)
Dry weight of 50lbs (23kg).
Crew - 2/3 Adults
 
The WATCH BELL 2.3 Pram Dinghy is a great little boat that we already sell as a kit but as it has been our production boat for a while we didn't sell the DIY plans - till now. She will row, motor or sail and has plenty of room inside for a boat of this size, ideal for learning to sail. These boats are easier to build than a stem dinghy of the same length, have more room and are often more stable.
The boat is built in plywood with a 6mm planked hull with 12mm transoms and 6mm framed bulkheads. The bulkheads form part of the buoyancy tanks fore and aft and should have the holes for small hatches to be fitted to allow for airing the tanks plus giving you somewhere dry to stow things while on the water.  There is also buoyancy built in under the centre thwart.
The hull is built using the "Lap Stitch" method of construction which quickly gives you the hull shape, held together with wire stitches or cable ties and then the laps are filled with epoxy. It is built upright either on the floor or on support beams at height that is easy to work at. The second option is better as it allows easier squaring and levelling of the hull later.
The boat can be built as a rowing, motor or sailing dinghy or all three! The basic hull can be built to row or motor with the sail rig added later which is an option with almost all of our designs. We can supply you with a professionally made sail as an extra. Some people think this type of dinghy is ugly but, when you consider that you get more space inside your dinghy and a more stable dinghy with this design, perhaps it might start to look more attractive.
This design was also built by a charity boat building project, we are patrons of along with Mike Perham (the round the world sailor at 14) and the local MP, in Stevenage. It is for 12 - 18 year olds to get the opportunity to build a boat and the sailing dinghy in the picture (right) was built by the volunteers. It shows it roughly rigged ready for a test sail.

Sandpiper 12  Rowing/Motor Dinghy



Length - 12’ - 2” (3.71m)
Beam - 4’ - 2” (1.27m)
Dry Weight - 80lbs approx. (36.29kg)
Load - 2 Adults plus 1 or 2 youngsters.
(Rows well with just 1)
 
A rowing dinghy - 12' & 14' in the style of the old Thames rowing boats.
These were originally designed to be built as traditional clinker boats in 1986 but re-designed for clinker plywood 1994 after a trip to Christchurch in Dorset and a row in a hire boat.
Only one of each length was ever built to the original clinker design which were used on the Norfolk Broads. Recently the design was changed to suit clinker plywood building and the Sandpiper 12 was the result.
 
THE "SANDPIPER" - A CLINKER STYLE HULL, 6 PLANKS PER SIDE, ROWING DINGHY THAT CAN BE USED FOR A DAY OF FUN ON THE LOCAL WATER. SHE IS 12’ - 2" IN LENGTH.   4’ - 2" WIDE AND DESIGNED TO BE A LIGHT ROWING BOAT THAT CAN BE TRANSPORTED ON A ROOF RACK OF A LARGER CAR OR ON A TRAILER. SHE CAN BE RIGGED TO SAIL BUT THIS DESIGN IS PRIMARILY INTENDED AS A ROWING BOAT. BUILT IN BOUYANCY CAN BE ADDED UNDER THE FORE AND AFT SEATS OR INFLATABLE BOUYANCY BAGS CAN BE FITTED.
 
Basic Materials Required
4 sheets of 6mm exterior or marine grade for the hull, 1 sheet of 12mm ply for the moulds and keel/centre frame, plus half a sheet of 9mm or 12mm for the seats, knees and breast hook, or waste from 6mm plywood or solid
timber to fit, (The moulds can be made from 12mm chipboard or MDF as a possibly cheaper option. Then the keel can be made up from a smaller sheet of 12mm ply although still 2.4m in length).

Sondes 230 Stem Dinghy
  

Loa 2.26m (7’ – 5”)
Beam 1.19m (3’ – 11”)
Draft 0.115m (0’ – 4.5”)
Dry Weight 18kgs (40lbs)
 
With 8 planks per side and styled on the Romney dinghy, this is a great looking dinghy that can be used as a tender, for solo fishing  or as a small sailing dinghy. We built one, tested it with our standard rig and found it to be a capable little craft. It rowed well and was easily pushed along with our electric outboard (24lb thrust) with two adults aboard.
Built using the clinker plywood method over a simple mould frame and then released to fit out with seats and trim etc.
This design will be available as the complete plans package with drawings, step by step instructions and full size patterns.
