SAILING YACHT DESIGNS & PLANS
24' to 35' 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.

We have 14 designs, as usual varying in type and style from the traditional Pinky to the more modern Nordia 10 - 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 24'
Simplicity 24
This is really a combination of our Simplicity and Swan ranges of traditional cruising yachts for a client who wants an easily handled and safe cruising boat for his young family to sail on the South Coast. We have compromised between the two ranges and gone for a simple construction using 2 chines. This produces a boat with excellent interior space as well as having very good sailing characteristics along with ease in construction.
Like the Simplicities, the construction is heavily based upon pre-shaped ply panels for the frames and girders which are slotted together and along with the bottom panel, form a stiff pre fabricated structure with no separate building frame and immediately ready to take the rest of the ply hull panels which are simply put on over size and trimmed later. Chines are made up from square section unbevelled Douglas Fir with the bevel being taken up by an epoxy fillet cutting down on much of the normal boat building work. The rig is simple with the mast in a tabernacle and the centreboard is below the cabin sole so as not to encroach on the accommodation. LOA 24’6’’ (7.47m); Beam 8’6’’ (2.59m); Draft 2’6’’/4’8’’ (0.76/1.42m); Sail Area 300 sq.ft. (28 sq.m); Disp. 3 tons; Ballast 2200 lbs. Note - the drawings now show several different keel options and the details for a hull with an additional chine.

26'6" SWALLOW TANCOOK WHALER
Ever since I saw the lines of the Tancook Whaler in Chapelle’s book Fast American Sailing Craft have been bugged by the wish to design a cruising boat using similar lines. The Tancook Whaler is one of those boats which evolved over many decades to do a particular working job, in this case to fish off the rough coast of Nova Scotia in all weathers and which at the same time took on a shape which to my eye is beauty itself They were fast and seaworthy and kept on moorings off the rocky coast all year round. If 1 ever get time to build one, this is my ultimate boat. This version has four berths, galley and wc and a rig which is designed for easy handling. She is round bilge but easily built using the French Carvel method. Ply bulkheads and backbone from given shapes are set up and covered in stringers. This structure is then skinned with 2 layers of 6mm ply each laid diagonally in 6’’ wide planks with both layers running in the same direction but with the outside layer overlapping the seams on the inside layer. Finally, the hull is covered with glass woven roving cloth in epoxy resin. LOD 26’6’’; LWL 20’10’’; Beam 8’; Draft 2’9’’/4’6’’; Displ. 5800 lbs Ballast 2500 lbs; Sail Area 338 sq.ft.

25' SONGTHRUSH DUTCH YACHT  
This pretty little Dutch style yacht finds it’s heritage in the Hegst fishing boats of the Scheldt area of Holland. Construction can be of ply or rough cheap timber for those who want a small, cheap live-aboard boat. She has room for two to sleep in the cockpit under a boom tent, double berth settee and large fore cabin for stowage. The cockpit/bunk fronts, frames and bottom hull panel are pre-shaped and form a prefabricated ply structure. The hull sides and bulwarks are then added oversize and trimmed later. The curvaceous bow is formed by 2 overlapping layers of ply for ease in construction.

NEW CR25 CRUISER RACER  
The CR25 (Cruiser racer 25) is a multi-chine ply yacht designed for easy unitized construction with ply bulkheads slotting into ply fore and aft girders to form the basic framework - the girders form cockpit seat and bunk fronts. Stringers are then fitted into the framework to form chines and after as much internal fitting out has been done, the hull panels are applied.
The standard layout has 3 main berths and 2 quarter berths plus separate wc/wash area, folding chart table and galley. The keel is retractable for easy recovery and launch and trailing.

NEW  25'1" KARI 4 SAILING CRUISER  

The Kari 4 follows in the tradition of her smaller sisters in having a hull with 4 planks per side. Her construction starts with the assembly of a plywood framework consisting of a ply fore and aft girder incorporating the centreboard case etc slotted together with ply frames and bulkheads. Stringers are then fitted at the plank lands and the planking can either be put on lapped (clinker fashion) or as a multi-chine shape. The Kari 3 has been strip planked and there is no reason why the same cannot be done on the Kari 4.

Maximum headroom as drawn is 5’6” (1.68m) and she has 4 berths (including a dinette/double), a wc compartment and galley.

The standard rig has a furling jib and high peaked gaff main but various other rigs could be used along with different keel arrangements—the standard steel centreplate allows a low draft but a fixed keel and inboard engine could be fitted.

LOD 25’1” (7.65m); Beam 8’6” (2.60m); Draft 2’1” (0.63m)/ 5’2” (1.58m): Sail Area 339 sq.ft. (31.56 sq.m.); Approx Wht. 3528 lbs (1600 kg); Ballast 1169 lbs (530 kg).

NORDIA 10
Nordia 10

Nordia 10

This design is for a Norwegian who’s brief was for a fast offshore and ocean cruising yacht which would incorporate an ample aft cockpit as well as a comfortable inside steering position with bunks for 5 to 7 people. The client is presently building the yacht and construction had to be both strong/modern and within the reach of the enthusiastic amateur. Speed and cost were also important considerations and therefore strip plank construction with epoxy glues was chosen because no fiddly boat building is required and the mould for the hull actually becomes part of the hull structure and is not wasted and leaves a clean interior where maximum space can be used for the layout. A cutter sloop rig was chosen for it’s speed and easy handling but the design can be modified to suit your needs as can the internal accommodation. The plans include lines and offsets but the offsets are given for the ply frames and therefore you can set the boat up without lofting. LOD 10m (32.79’); LWL 7.5m (24.59’); Beam 3.4m (11.15’); Draft 1.55m (5.08’); S.A. 52.4 sq.m (564 sq.ft) Displ. 7500 kg (7.38 tons).

Based upon the Pinky fishing boats of Maine and Nova Scotia this neat craft, instead of carrying the traditional cargo of sardines has been laid out with a roomy accommodation for 4 or 5 people in 2 separate compartments. Her double ended hull and deep draft make her a very seaworthy craft. The gaff ketch rig is easily handled and the small self draining cockpit has been designed for ocean sailing.

FULMAR 26'3"  
At 26'3" length on deck, the Fulmar is a heavy displacement cruising yacht which fits a spacious layout into a relatively short length. Her construction is of multi-chine ply extensively using pre-shaped ply bulkheads and girders.  The forward accommodation is open plan with a large dining area which can convert to berths followed by a galley and chart area as the main working spaces in the centre of the boat. The aft cabin has a double berth with plenty of stowage space and an engine can be fitted below the centre cockpit or outboards can be accommodated in a locker just in front of the transom. The position of the cockpit allows tiller or wheel steering and for additional protection there is space for a doghouse.

25'5" SHANGHAI
This yacht was designed  a modern interpretation of the junk type for music arranger and composer Mike Hale. She had to be a safe and comfortable cruising yacht with cross channel capability as well as the ability to venture into shallow waters. The hull is of multi-chine shape and is assembled from pre-shaped ply components with fore and aft girders also acting as bunk fronts bilge board cases and locker fronts. She has a large and deep cockpit aft and the cabin is laid out for 2 to live comfortably. The outboard is housed in an aft enclosed well. There are twin bilge boards housed in the bunk/seat fronts so that they do not encroach on the living space. The junk rig may be supplemented with a reacher and all sail controls are led back to the cockpit.

HART 27 MOTOR SAILER  
I was commissioned to design a GRP family motor sailer with the emphasis on getting the most comfortable "package" into 27' LOD. The design has centre raised deckhouse which houses the galley and dinette with interior steering position. Forward of this is a double cabin and aft is a cockpit with exterior steering position followed by another double cabin giving up to 6 berths in total. As mentioned, hull and deck construction is detailed for GRP but the mould/building jig details allow her to be made in strip plank (and we can advise on the change from a grp deck to wood). the drawing package shows all the construction details for the grp hull and deck/superstructure plus interior fit-out and joiner details.  Details of machinery installation, sail, spar and deck plan are not as yet available but could be quickly drawn up.

MARTLET 30 GAFF CUTTER
This is a design commissioned by someone who built one of our clinker ply Kane Suffolk Beach Punts and who wanted a safe, comfortable deep water cruising yacht which could also find it's way up relatively shallow creeks. For her length, she is to my mind the ultimate cruising vessel with the capability to cruise distant shores and then to travel up small rivers.  The hull is modelled on the Pilot Cutter for it's seaworthiness and easily driven form. She is built using the clinker ply method over a rigid framework of pre-shaped ply bulkheads and girders. She has twin bilge keels so that she can dry out along with a central ballast keel and centreplate for windward ability. Accommodation is comfortable with bunks for up to 6 crew, a large wc and spacious galley plus plenty of locker space. The engine is 35hp and she is able to have large tanks for extended cruising. Both yawl and gaff cutter rigs are shown. 
Right and below - the planks go on.

Below are photographs taken from Brian O'Hara's book "Not of Sound Mind" (ISBN9781492916710) which describes the construction and launch of his beautiful example of a strip planked Martlet "Knot Free" (the photographs are used with Brian's kind permission). The book is not a construction manual (although there are many descriptions of how various aspects of the build were tackled including fitting the keel/bilge keels and the hull turn over) but offers helpful advice on tacking a project of this size. The book includes many useful photos of the construction process and can be ordered from Amazon.
The photo below left shows Brian beside the Martlet at an early stage in the construction.
 
Brian's book is available from Amazon and describes how he, his son Neil, daughter-in-law Irene and several friends worked together over several years to build this beautiful example of the Martlet.

NEW  DILYS 25'8" CATBOAT
Safe Harbour 12

Dilys is a Welsh name and means “perfect, true and reliable” which is just right for this sturdy little ship—it also happens to be my wife’s name and the meaning certainly fits her too! This is a 4 plank per side ply on frame version of the well known North American Catboat—boats with a generous beam giving enormous stability and vast room inside for their length.

She has the standard layout for a catboat of this length of just 2 berths with comfortably sized wc compartment and galley and very large cockpit. She could of course, with some redesign, take 4 berths. Maximum headroom as drawn is 6’ (1.83m).  The drawings give details for both an inboard diesel engine installation and an alternative outboard well.

Many had a centreboard rather than a fixed keel and she could also be adapted to take this arrangement. Construction is based on a modern pre-shaped egg-box type plywood framework of frames/bulkheads slotted together with fore and aft girders.  

LOD 25’8” (7.82m); Beam 12’ (3.65m); Draft 4’2” (1.27m): Sail Area 515 sq.ft. (47.88 sq.m.); Displ. To WL. 12546 lbs (5690 kg); Ballast 4080 lbs (1850 kg).
