NEW BOAT DESIGNS & CURRENT
DESIGN WORK

On this page you will see some of my most recent designs - most of my design work is commissioned with the agreement that SF Design can put the new design into our Stock Catalogue to make it available to all boat building enthusiasts.

I normally have at least 5 new designs on the drawing board at any one time and to keep you right up to-date, here is a list of my current work :-

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)

22'8" RANWORTH BROADS SAILING CRUISER

At last, a bigger Highlander dayboat - so really a pocket cruiser or small yacht. She has been drawn up for clinker ply construction over a framework of ply girders and bulkheads but the hull planks shapes are also given for her to be built using the stitch and tape method. She is set up with an outboard well and a large cockpit which could take a boom tent—the cabin is big enough for 2 berths and a small galley and Porta Potti WC. Maximum headroom as drawn is 4'5" but she has a size of hull that could take a modified cabin arrangement.

Her centreplate makes her ideal for trailing and gunkholing. The centreplate pivot is on the outside of the hull and the lift is via a tube into the cockpit so that there are no leak problems. 

LOA 23’ (7.00m); Beam 8’3” (2.52m); Draft 1’9”/4’10” (0.53/1.49m); Displ. To WL 3749lbs (1700kg); Approx. Weight 2205lbs (1000kg); Ballast 551lbs (250kg); Sail Area 238 sq.ft. (22.15sq.m)

HIGHLANDER 23

Using the Micro 8 as a starting point l have drawn up a boat with 25% additional length which, in such a small craft, gives a lot of additional useful space for stores and simple creature comforts. She is designed with the "Around in 10" in mind. Construction is just the same with simple stitch and tape used over a basic ply framework of fore and aft girder and bulkheads—l have tried to keep the overall construction weight to that of the Micro 8.

Some of the ballast is water and she uses a simple staysail type rig with controls led inside the boat along with the steering system.  

LOD 10’ (3.05m); Beam 5’4” (1.63m); Draft 2’4”/4’3” (0.70/1.3m); Displ. To WL 3749lbs (1700kg); Approx. Dry Weight 1103lbs (500kg); Ballast 386lbs (175kg) of lead and 441lbs (200kg) of water; Sail Area 75.25 sq.ft. (7 sq.m).

MICRO 10

The Deben 400 is a rowing skiff inspired by the Cornish Flashboats—they were 18’ or more in length and used around Fowey for river transport. This version is just under 13’ long and for single recreational rowing.
She has a narrow flat bottom panel and 3 side panels with a fairly narrow WL beam and slack bilges for minimum wetted surface area.
Construction is simple stitch and tape and 4, 5 or 6mm ply may be used.
LOA 12’9” (3.89m); Hull beam 3’11” (1.19m). Approx. wht. in 4mm ply 60lbs (27kg).

DEBEN ROWING SKIFF FULL PLANS COST 

Snipa’s (pronounced Sneepa) are traditional clinker Nordic Fishing boats with a reputation for excellent sea keeping qualities and stability. Construction has been kept much like the original boats although plywood planking can be used instead of solid wood.

  Many traditional boats have been converted with an inboard engine—the installation of a Farymann 7.5 hp engine is detailed as an option. Ballast used to be stone and this can still be used although a ballast keel is also detailed. She is built over frames which may be traditional solid or laminated and which are computer faired.

  LOD 18’7” (5.67m); Beam 6’8” (2.03m); Draft 2’1” (0.65m); Sail Area 156 sq.ft. (14.54 sq.m); Approx Wht. 1808 lbs (820 kg) including 551 lbs (250kg) of ballast.

SNIPA FISHING BOAT

The Port Pegasus is a clinker boat which may be used as a pure rowing boat or fitted with a small diesel (ie Farymann 7.5) as a small motor launch with classic appearance.

As a general purpose launch, she could be fitted out in a variety of different ways—ie. With a small cuddy, centre console arrangement or even with an appropriate sail/keel plan. The drawings give the computer faired mould shapes and building jig details for modern clinker construction—framing incorporates the plywood bulkheads etc. Mid hull depth is 1’9” (0.53m).

LOD 15’1” (4.59m); Beam 5’7” (1.70m); Draft (ex. Engine 7 1/2” (0.19m)); Draft (incl. engine 1’ 2 1/2” (0.37m)); Approx Wht. (ex. Engine 331 lbs (150kg)); Approx. wht (incl. engine 573 lbs (260kg)).

PORT PEGASUS PLANS COST

The Greenland 19 has a simple V bottomed single chine stitch and tape plywood hull designed to ride out rough water with ease and to have a good turn of speed. She has an optional daggerboard box to help in directional stability.

The deck is strip planked over temporary moulds. She has water– tight compartments fore and aft as well as plenty of storage space.

LOA 19’ (5.8m); Beam 1’ 11 1/2” (0.60m); Approx. weight 50lbs. (22.7kg); Approx Capacity 325lbs (147 kg).

19' GREENLAND KAYAK FULL PLANS COST 

This 26’ version of the Golden Bay has the same fairly high and flaired bow sections designed to throw off spray which flow into aft sections which have tumblehome giving her a generous waterline beam for maximum stability.

These drawings show her with a canvas top and a 34hp diesel engine but she could take a solid cabin similar to that on the 21’ version and she may be powered by a steam plant (around 15 IHP) or by electric motor.

Construction is for Cedar strip over computer faired moulds. The interior shows simple open plan seating for 8 people but she may be fitted out with other arrangements.

LOD 26’5” (8.03m); Beam 6’8” (2.03m); Draft 2’9” (0.84m): Approx Wht. 3308 lbs (1500 kg).

26' GOLDEN BAY LAUNCH PLANS COST

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).

25'1" KARI 4 SAILING CRUISER

The Ruby 19 is based on our Ruby 22 double chine plywood steam launch. In the case of the Ruby 19 a client wanted a shorter version of the 22 to be built in steel which meant widening and deepening her to take the steel weight. Having produced the steel work drawings we have decided to make a complete set of plans for both the steel and plywood version.
If she is built in plywood, she has a very high carrying capacity and would make a roust work launch. The plans show an open arrangement but there is no reason why she could not take a cabin with accommodation and/or a wheelhouse.
The plans show details for steel construction as well as ply over frame construction.

LOD 19’ (5.80m); Beam OA 6’7” (2.00m); Draft 2’5” (0.73m); Displ. To WL 4851lbs (2200kg); Approx. dry weight in plywood 2536 lbs. (1150kg).
