DOUBLE-ENDERS

Study Plans are available for these designs - remember a study plan gives you more details and a wood materials list usually on two A1 sheets, so that you can cost out a project before ordering the full plans. When you order the full construction plans you do not need to order the study plan as well, as all the study details are on the full plans.

Note - In the particulars for each design, the dry weight is given for guidance only and will vary depending on the grade/density of plywood and solid wood used - different thicknesses of ply are often used by builders and the dry weight figure is based on the thinnest ply specified.
Also the Guidance Use comments are given in good faith and are based on feedback from previous builders etc and based on standard weight adults - contact us if you want further clarification before ordering/building.
Please also note that we give the computer faired mould, inner stem and transom shapes plus the building jig details for clinker ply construction where stated and recommend that the builder purchases a good manual on this method of construction to use with these details. E & OE

 

We have 11 designs ranging from traditional canoe yawls to Polish Fishing boats and Scottish Skiffs :-

15' MEDWAY DOBLE
Medway Doble 15'
We were asked by a Portuguese client to stretch our standard Medway Doble to produce an easily rowed craft which could be carried under the bridge deck of a large cruising catamaran and used both as a tender and as a lifeboat. This version has the same easily driven hull shape which, with it's double ends, will ride a following sea. The rudder arrangement allows a small outboard to be hung on the narrow transom top aft of the rudder stock She has built-in buoyancy compartments and stowage areas fore and aft and also under side benches. Construction takes 6 sheets of 5 or 6mm plywood and her overall weight will be around 150 lbs. (68 kg). She uses a daggerboard for simplicity but she could also have a centreboard. The simple gaff rig has a self tacking jib so that she can be sailed easily by one person.  LOD 14'10" (4.50m); Beam 4'7" (1.39m); Draft 6"/3'2" (0.15/0.96m); Sail Area 95 sq. ft. (8.83 sq.m.).

16' IONA SKIFF

Iona SkiffIona Skiff
For those who want to build a classically designed double ended clinker craft, this boat has been developed from the Shetland Skiff and North American Peapod dinghy. Construction is greatly simplified from the conventional clinker method and kept to a low cost by using a stringer system to which 1/4’’ ply strakes are pinned and shaped to form a simple clinker hull with no steam bent frames or conventional copper riveting. The stringers are initially positioned over temporary chipboard moulds and fastened to a backbone and the ply planks are then cut oversize and glued to the stringers before trimming to size. She is a graceful craft for the more advanced builder or the beginner willing to study, practice and take his time. Beam is 4’9’’. The plans are on a single sheet showing lines, offsets, basic construction method and sprit sail plan. Details are also given of an alternative gunter sail plan and centreboard arrangement.

16' ISLAY SKIFF
Islay Skiff

The first photo above is of a strip planked version of the Islay with additional depth added to the hull - the other 2 photos show a clinker/ply version by Rob Johnsey to the original plans (which also give details for a stitch & tape version).
The Islay is a recent development of our Iona design for a client who required a graceful boat with more beam and a little more sheer. He also wanted a traditional cutter rig with a jaunty looking bowsprit. Construction can either be by the strip planked method (and computer lofted mould shapes are shown for this) or by the same method as that used on the Iona design with stringers and backbone laid over a system of mould shapes with the ply planking applied oversize and defined by the stringers. This gives a traditional clinker boat appearance but uses a much easier and quicker method to achieve it. Alternatively. plank shapes can be supplied for stitch and epoxy construction. LOD 16’5’’; Beam 5’6’’; Draft 1’/3’6’’; Sail Area 126 sq.ft.; Approx. wht. 350 lbs.
Details are also given for a transom version.

Below is a beautifully built strip planked version.

Below is an example where the stringers/ribbands have been left in the clinker hull as longitudinal framing by Mike Lowson of North Boats.

17'3" KON BOT PUCK
Puck
Not much has been written in the West about the traditional working craft of the East European countries but they had some fine craft and this is just one example of them. The KON was one of the smaller types of boat working on the Baltic around the Bay of Gdansk mainly in net fishing for flounder.

Puck is our update on one of these craft. We have developed all the plank shapes for simple stitch and epoxy construction using 9mm plywood. 13 sheets are required for both the planking and decks and frames. We have changed the traditional dagger or leeboards for a steel plate centreboard and we have retained the sprit rig used on many of these boats. PUCK may be fitted out in a variety of ways and she is big enough to take a small cabin. She is a heavy working boat and would normally carry around 300 lbs. of scrap ballast. Details of an outboard well are shown and we can supply drawings covering various changes to suit your own requirements.

17'3" GDANSK

Gdansk Polish Fishing Boat
The ‘‘Gdansk’’ is a modified version of the ‘‘Puck’’ Polish fishing boat design for a client who didn’t mind giving up the double ended hull. Her basic particulars are similar to the ‘‘Puck’’ design but she has a transom stern, a cuddy and side decks. The transom is narrow at the waterline so that the beautiful lines of the Polish fishing boats are not upset and the additional width above the waterline gives more sitting area. Again the design may be adapted and fitted out much as you require and the cuddy may be lengthened or shortened or finished as an enclosed cabin. With the cuddy. the mast is stepped in a tabernacle.

KARI 2 FAERING  

The example above is by Jose Granell

Kari Faering
We were asked to develop the plank shapes for a replica of a 4 oared Faering from some lines that had been taken off the boat some while back. The client was the husband of the Great Granddaughter of the owner who had the original built in 1892 for the sum of 70 Kroner (£3.10.0). The original is now in a museum and still in excellent condition, having been used by several generations for holidays and a few long expeditions. We have now taken the original lines and produced construction drawings for modern stitch and epoxy construction using plywood. The hull is a close resemblance of the original but we have given her a deeper keel to enhance her windward performance (the originals often used a dagger board) and a larger rig. The plank shapes are shown on the drawings along with frame shapes. A fascinating and very beautiful boat. LOD 18’; Beam 5’4’’.

15' LILLIE CANOE YAWL  
This lovely craft was commissioned by Tom Dunderdale after reading the series of articles in the Classic Boat magazine on the 13’ strip planked canoe yawl Ethel. The idea was to produce a canoe yawl of similar style to those of the last century used by Baden Powell and MacGregor and which formed the basis of modern canoeing today but using modern ply/epoxy construction methods with computer generated plank shapes. Her length is based upon the maximum length of plank that you can get out of 2 sheets of ply and we have increased the beam a little over the original Ethel design which allows more extensive cruising and even the ability to sleep on board. She uses 6 sheets of 6mm and one of 9mm ply in her construction. The standard set of plans show details for stitch and epoxy construction using 7 planks per side to give a beautiful round bottom hull shape and details are given for her to be fitted out in classic style with a lug yawl rig. The plans include mould shapes and construction details for her to be made using the strip plank method. Tom reports that up to a force 2 she will sail herself both before and into the wind hands off allowing the helmsman to drink his beer  in comfort. Above that, she handles herself with grace and she rows very well with excellent tracking.

18'4" JIM CANOE YAWL  
Since designing Lillie, we have had several enquiries for new canoe yawl designs. I think that this is partly due to their obvious elegance in shape and function. They are beautiful craft and represent a very personal form of sailing. The journeys of exploration and pleasure by MacGregor, Baden Powell and others in the early sailing canoes are legendary and conjure up visions of simple rugged sailing into inlets and estuaries and around European coastal islands. The simplicity of this type of boat is very often refreshing after the sophistication (and complication) of many modern fibre-glass craft. The standard building method is based upon stitched ply/epoxy construction but she could easily be built using the strip planked method. Provision is made for simple scrap steel or lead ballast in the bilges below the sole. The sole area itself is large enough for comfortable sleeping by 2 people forward of the thwart with a third perhaps aft. The simple lug rigged main and gunter mizzen have been used to keep sail handling simple with easy reefing and to keep the spar lengths down to fit into the length of the boat. LOD 18’4’’ (5.60m); Beam 5’6’’ (1.68m); Draft 11’’/3’5’’ (.29/1.05m); Sail Area 156 sq.ft. (14.57 sq.m.); Wht ex ballast 507 lbs. (230 kg); Ballast up to 321 lb. (150 kg).

16' CASCO BAY CANOE YAWL

The Casco Bay 16 was designed for Maurice Byrne of the Boatyard Upstairs for a Swiss client who wanted a fast, easily handled canoe yawl for use on his home lakes. We have developed an efficient and stable hull form with slight influence from the Casco Bay Peapods. We have kept the waterline length as high as possible with short overhangs at each end, but still retained a sweet looking hull with an attractive sheer line and well cambered decks. Construction is for strip planking (veneered or simply glass sheathed). She has an inboard rudder which hinges up into a box when she comes ashore and her elegant lug yawl rig can be altered by removing the mizzen and stepping the main further aft. the drawings show details for curved spars but these could be straight.

 26' WHALER ROWING BOAT
Marlow 27

The 26’ Whaler has been designed to get the youth interested in activities on the water from building the boat to mounting expeditions. She can take 10 crew with at least 8 rowing and has plenty of space for stowing gear. Her shape has been based on the British Naval Whaler with it’s rounded bow and ample midship section. But in this instance, for ease in construction and to keep building time and costs down, we gave gone for a multi-chine hull shape in plywood.

Construction is simple stitch and tape or ply over frame with 4 planks per side. The hull is symmetrical about amidships and can be built and stored in 2 identical halves if required.

Although not drawn yet, she could take a simple rig with rudder etc. Full construction (which includes seating and sole etc) takes approximately 20 sheets of 9mm plywood.

NEW  24' NEW BEDFORD WHALER
Marlow 27

 The New Bedford Whalers were renowned for their ruggedness and sea-kindly manner. Typically they were 28' or 30' long. I was asked to draw up the lines for a shorter version for a film company and decided to use this design work as the basis of a full set of plans for a clinker/ply version.

 She can be built without the sail rig, rudder and centreplate as a very efficient and seaworthy rowing craft for a crew of five - four rowers and steersman.
