20' to 24' IN LENGTH

 

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.

There are 17 designs as usual varying in type and style from the traditional Black Swan to the more modern Ailsa  - there are study plans (A1 sheets with sections, construction details and a wood materials list, for most of these designs - for further information please see the price list on the main page.

 

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

SIMPLICITY 20'  
Following along the same lines as her smaller sister, this cruiser is an ultra simple boat with plenty of space and performance for her size. She has room for 3 or 4 berths plus galley and portable wc. Construction simply involves fixing pre-shaped side panels to ply frames, adding chine and gunwale stringers on the outside and then applying a double thickness of ply to the bottom. Other pre-shaped pieces are then added before fixing a ply ballast box filled with scrap iron and cement. Centreboard or bilge keels may be fitted and she has 4 berths, space for a galley and wc and a handy gunter rig. She is simple but immensely strong and efficient.

PIONEER 21' DORY/SHARPIE  
In this design a client asked for the largest and safest single handed offshore yacht that he could get on a very limited budget. For your money. a dory or sharpie gives you more length per £100 than any other shape. Add to this type of hull a simple box ballast keel filled with scrap iron and cement and you have a very seaworthy, inexpensive and quickly built design. The junk rig has been used for it’s safe easily handled single handed qualities and the design has been set up so that virtually all operations are controlled from the security of the doghouse. The construction drawings are for Foam Sandwich Fibreglass building. However, the design can easily be adapted for simple ply construction and the keel arrangement may be altered to bilge or centreboard (we will be very pleased to advice and supply drawings for any modifications to any of our designs).

BLACK SWAN 22'
Black Swan 22
The bottom 2 photos above show an example being built by Henner Ostermeyer in Germany.
The Black Swan is a stretched version of the White Swan for Dr. Carcereri of Verona who wanted good headroom in a small traditional gaff cutter. In fact she has just over 6’ in the galley area and an accommodation that can be altered to suit your own requirements. She has room for a small inboard diesel engine or as an alternative, an outboard well could be incorporated. There is plenty of room for stowage and the centreboard case has been kept as low as possible by keeping the centreboard pivot outside the boat and through the keel. The case is only 8’’ above the sole height. Construction is based upon pre shaped ply frames and fore and aft girders which form the bunk/cockpit fronts. The hull panel shapes are given on the drawing so that the planking goes on using the stitch and glue method. This keeps construction costs and time down to a minimum and requires only basic skills. LOD 22’6’’ (6.84m); Beam 8’4’’ (2.55m); Draft 2’5’’/4’5’’ (0.74/1.36m); Sail Area 340 sq.ft. (31.55 sq.m); Disp. 2.75 tons; Ballast 1900 lbs. The plans also show the details/moulds for strip planking the hull.

24' MAYFLY SHARPIE  
A neat little ply sharpie of simple and cheap construction with 4 berths (and room in the cockpit for more) for exploring estuaries and gunkholing. With it’s simple unstayed rig, it is ideal for the small family. Uses disposable sand or gravel ballast. Based upon the North American working sharpie. May be built with centreboard. Construction is similar to our Song Thrush using pre-shaped ply bulkheads and girders locked together with the hull bottom panel to form a strong prefabricated structure to which the sides are added.

21' RONA YAWL  
This little ship has been designed for the sailing author Derek Harvey and incorporates many ideas gleaned from his years of sailing experience. The starting point for the design was the requirement for a trailable boat with comfortable internal living space for 2 with a large and practicable cockpit area. The rig had to be both efficient and easy to use from the cockpit and she had to carry a large outboard for motoring out to sailing grounds. Clinker ply construction using 7 planks per side was chosen to give the hull a sweet appearance which was fairly easy to construct (details and plank shapes are also given for stitch and epoxy construction and she could be strip planked). For easy trailing she has twin pivoted bilge boards which do not encroach on the accommodation and are housed under the bunks and she carries some water ballast. Inside there are 2 large bunks with galley and saloon/chart table and a locker for a Porta Potti. The layout could be re arranged to take more berths. She has a foredeck well and she carries a gunter yawl rig for good balance under reduced sail. LOD 21’3’’ (6.48m); Beam 8’ (2.4m); Draft 1’5’’/4’ (.42/1.2m); Sail Area 280 sq.ft. (26.07 sq.m); Displ. 3938 lb. (1786kg); Approx. trailing wht 3000 lb (1361 kg); Ballast 992 lb (450 kg).

These pictures are of a beautiful example built by Roger Boxall - "Emily" is presently up for sale and this is an excellent chance own a fine little ship - contact us for details or refer to the Watercraft Magazine.

22' KITTIWAKE CANOE YAWL  
I think that the canoe yawls of the early part of this century were some of the most beautiful cruising yachts ever designed. They may not have had as much room inside as their modern counterparts, but they were sea kindly craft with an easily handled rig and a grace and charm all of their own. Kittiwake is our version of the old canoe yawl using the modern ply/epoxy method of construction. She has 6 plywood planks per side which are stitched together along with the ply backbone girder and bulkheads. All the seams and joints are then bonded with epoxy and the hull sheathed in woven roving. She has an ‘L’ shaped steel centreboard which is housed below the cabin sole and operated from the cockpit. The centreboard pivot is located outside the hull so that there are no leaks. Ballast, in the form of scrap iron or lead is housed in 2 steel ballast boxes to keep cost down and to make the engineering side of the construction as simple as possible.
She has room for 2 or 3 berths, a wc and galley and she can have an outboard well in the cockpit. Her yawl rig, apart from being traditional, is in easily handled balanced areas allowing her to be sailed with just the jib and mizzen up. We can also produce the computer faired mould shapes and details for strip planked construction. Other keel configurations can also be drawn up. LOD 22’ (6.70m); LWL 19’4’’ (5.92m); Beam 7’ (2.10m); Draft 2’2’’/4’8’’ (.66/1.42m); Displ. 3638 lb (1650 kg); Ballast 1323 lb (600 kg); Sail Area 277 sq.ft (25.79 sq.m).

SKYE 21'
Skye 21
Here is a smart little yacht combining 2 modern building techniques to make construction as quick and simple as possible. First of all, the pre-shaped ply bottom panel and longitudinal girders are put together with frames and bulkheads. To make things really simple, the hull side frames are all based upon one master curve and once set up, the sides are constructed from strip planks no more than an inch wide, bonded with epoxy. The drawing shows a central ballast keel or centreboard options and the accommodation can be arranged to suit. There is an outboard well aft and she will take up to, 4 berths. The centreboard version lends itself to car trailing. LOA 20’6’’; Beam 7’3’’; Draft 1’10’’ (keel version).

21' SKUA

 

The photos above show a version of the Skua with schooner bow and bilge boards by Mr. Davies of Wales - the photos below are of an example built by Toni Reiter of Holland.
 
The attractive little SKUA has been designed for trailer sailing. She has the option of carrying salt water ballast in 2 tanks built-in to the boat and giving her a total ballast weight of 550 kg. 480 kg of this is water which is discharged when the boat is recovered onto the trailer giving her a trailer weight of around 900 kg. She has 2 comfortable berths a w.c. and galley but she could be fitted out with berths under the cockpit seating. She has an outboard well and a deep safe cockpit and foredeck well. The gaff sloop rig is mounted in a tabernacle and her centreboard arrangement has been designed so as not to encroach on the cabin space, is raised from the cockpit and pivoted outside the hull to prevent leaks. There is a choice of two methods of construction - the computer faired mould shapes are given for strip planked construction and the panel shapes and details are given for ply epoxy construction. LOA 6.48m (21’3’’); Beam 2.38m (7’10’’); Draft .63/1.38m (2’1’’/4’6’’); Sail Area 22.92 sq.m. (246 sq.ft.); Displacement 1500kg (3308 lbs); Ballast 550kg (1213 lb); Trailing wht. 900kg (1985 lb). Details are included for a schooner bowed cutter version with a larger volume hull - details are also included for a lug rig and bilge boards.

AILSA 22
Ailsa 22
Ailsa 22
Ailsa 22
The Ailsa 22' is a lightweight trailer sailer which uses plywood/epoxy construction for most of the hull and deck and modern strip planking for the round bilge area. Pre-fabricated plywood sections are used for the basic hull structure allowing a lot of the construction to be done in small easily handled units before the whole hull is put together. Much of the initial construction can therefore be started well away from the final assembly site. The standard layout has four berths and a galley in an open plan arrangement with a separate w.c. compartment. Trailing is made easy because she has a mast mounted in a tabernacle and simple lifting bilge boards rather than a fixed keel. The boards are a larger version of those used in our Lynx 14 design and work in slots outboard of the main accommodation using a hoist arrangement which is controlled from the cockpit. To keep the trailing weight down the ballast is divided between permanent solid ballast and water ballast tanks which are filled once the boat has been launched. The design could take different keel and ballast options if required.

20' PORT LOUIS
This attractive pocket cruiser was designed for a client on the island of Mauritius and has some of the hull design features of the indigenous craft with their sweet and not over wide transoms married to traditional English work boat hull shapes with plumb stem and fairly hard bilges giving excellent stability and sea-keeping qualities. Construction is for strip planking over computer faired mould shapes. She has an inboard engine as well as a swing keel which does not intrude into the cabin space. The cockpit is large and the cabin is laid out generously for 2 crew.

24' BEAUMARIS

Beaumaris 24
Beaumaris
The Beaumaris 24 is one of several trailer sailers for strip planking that we have had on the drawing board recently. This particular example has accommodation which includes 3 or 4 berths, a galley and a Porta-Potti w.c., all combined with a good sized cockpit. There are 2 keel alternatives - one with a centreplate (which is kept below the cabin sole) and the other with a deeper fixed keel allowing you to install an inboard engine. The cabin is taken right out to the sides of the hull to give comfortable sitting space below.  Initially the rig is based upon a simple standing lug rig set on lightweight masts and spars, but she could take other rigs - details of an alternative gaff cutter rig are included.
BeaumarisComputer faired mould shapes are given for strip planking the hull which has firm bilges ending in a sweet full wineglass shaped transom. LOD 23'6" (7.16m); Beam 7'6" (2.29m); Draft 2'/4'4" (0.61/1.32m) or for fixed draft version 2'6" (0.76m); Approx. weight 3220 lbs (1460 kg); Ballast 1047 lbs (475 kg); Sail Area 266 sq.ft.

This is a multi-chine plywood entrant for the Mini-Transat race which takes competitors across the Atlantic to Antigua via the Canary Islands. It is known as one of yachting's most dangerous races and is fought by boats with a maximum length of 6.5m. We have been asked to draw up a design for a Canadian client which uses standard stitch and tape building methods with non exotic materials for amateur construction. She incorporates water ballast along with a lead ballasted bulb on a high aspect ratio keel, inclined twin rudders and built-buoyancy. Whilst designed for a specific race, she would provide fast exciting sailing in coastal waters (the keel can be raised for easy transport) and has room for more than the 2 berths shown. LOD 21'4" (6.5m); Beam 9'10" (3m); Draft 6'4" (1.92m); Total loaded displ. 2814 lbs. (1276 kg); Total ballast 1574 lbs. (950 kg); Working Sail Area 458 sq.ft (42.6 sq.m.). Plans for the hull/superstructure only are available.

23' YAMATO JAPANESE FISHING BOAT
This is a modern plywood updated version of the Japanese Yamato fishing boats. The client in this case, worked in Japan and admired these boats - he was able to obtain the lines from one example and gave it to us so that we could draw up a simple plywood version. the simple flat bottomed double chine hull form is similar to some of our motor boats and is an easily driven and stable shape. She is mainly open with large lockers and a small forward cuddy. sail power is provided by a simple unstayed lug rig and she has an inboard 9 hp diesel. Along with the centreplate and skeg is stub bilge keels which allow her to dry out upright. All in all, she is a practical sea boat.

Construction is ply over frame with the frames, girders etc set-up on a strongback. LOD 23'7" (7.2m); beam 7'2" (2.18m); Draft 1'7"/4'4" (0.49m/1.33m); Approx. wht. 2977 lbs (1350 kg incl. 992 lbs/450 kg of ballast; sail Area 192 sq.ft. (17.8 sq.m.).

Added to the standard plan set are two drawings, one giving the details for a gaff sloop rig and the other for a steam plant installation as an auxiliary.

24' TASMAN JUNK RIGGED YACHT
The Tasman is a multi-chine plywood yacht designed for long distance sailing for 2 crew, which uses an egg-box frame system of plywood fore and aft girders slotted together with plywood bulkheads—once stringers have been fitted, the ply hull panels are then applied making construction quite simple.
There are 2 steel bilge plates which are housed in the bunk fronts and the junk mast is hinged in a tabernacle for easy lowering. Steering etc is set up for control from inside the yacht although there is a cockpit and outboard well.

 22'8" RANWORTH BROADS SAILING CRUISER

The Ranworth is a typical Broads type sailing cruiser with generous beam and relatively large sail area to catch the wind above the reeds. She has 3 berths and space for a small galley and wc compartment. The cockpit is generous in size and could take a boom tent. The cabin top lifts to give more headroom.

Construction is for Cedar strip planking over computer faired moulds. There is space for a small inboard engine in the forepeak (which could be connected hydraulically to a prop. shaft) however many would use an outboard.

LOA 22’8” (6.90m); Beam 8’ (2.44m); Draft 3’2” (0.96m); Displ. To WL 4851lbs (2200kg); Approx. Weight 3087lbs (1400kg); Ballast 1103lbs (500kg); Sail Area 316 sq.ft. (29.4sq.m).

NEW  23' MARTLET PILOT CUTTER

The 30' LOD Martlet has been a popular design and represents a lot of seaworthy boat for her length but I have often been asked about a smaller version - a design which embodies the robust pilot cutter looks and sea keeping qualities and the ability to cruise far a field but, in a smaller package. I was eventually commissioned to do the drawings for a 23' version and jumped at the chance - so here she is.

 The original 30' Martlet was drawn up for clinker plywood construction over a fairly extensive ply framework and then strip plank construction details wwere added at a later date. With her 23' sister, we start off with strip plank construction and eventually, when someone asks for it, ply construction (either clinker or multi-chine) will almost certainly be added to the design package. So, as usuall the computer faired mould, inner stem and transom shapes are given to be set up on a strongback before planking starts. The planking could be done in a number of ways - single Cedar with a glass sheathing, a thinner Cedar core with 1 or 2 veneers on the outside etc. Even cold-moulded if you want - we can give advice on relevant scantlings for the method you choose although a single Cedar strip sheathed in glass is specified on the plans.
 she has a relatively shallow draft with a long central ballast keel and steel plate bilge keels - other keel configurations could be drawn up to suit.

 The accommodation is laid out with forward 'V' berths, a small wc compartment and galley opposite and then a further two pilot berths aft. there is room for a 9 or 10hp inboard plus a generous cockpit with plenty of stowage.
