BOAT DESIGNS & PLANS
FOR MOTOR BOATS 16' TO 20' 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 6 designs, of
various different styles and types :-

POWER 1.3
 |
The Power 1.3
is a development of the original Power 1 design. In this case, we were asked to
produce a simply built hull with more capacity and suitable for offshore and
estuary conditions. We have retained the flat bottom section which eases and
quickens construction but increased both the beam and hull depth substantially.
The drawings give details for welded aluminium construction but she could easily
be made using the hull panel shapes given on the drawings, in plywood. Water tight side bench seats are shown aft and a separate buoyancy compartment forward but fit out can be altered to suit and a cuddy or wheelhouse could be fitted. LOD 17'2" (5.23m); Beam 7'6" (2.28m); Construction weight in aluminium 595 lbs (270 kg). |

This example is by Matthew Clark and achieved 30 knots with a 100hp outboard. |

|
This
craft is a widened and a more sophisticated version of our Power 2 design. The
bottom panel has been slightly veed to give a softer ride and her depth has been
increased. This along with her wider beam enables her to be fitted out with a
more extensive cabin structure and with larger tanks etc. Construction starts by
assembling the frames and the transom onto the ply girder (backbone). The
builder may then attach chine stringers to the frames and fit the hull panels
oversize (to be trimmed later) use the panel shapes given on the drawings and
stitch their edges together along the chines, later to be finished with epoxy
filleting. The drawings show the full hull construction and details of a wheelhouse and forward cabin which may be altered to suit the builder's own requirements. Engines may be mounted aft or in a conventional drive position depending on how the boat is to be fitted out. Her hull shape has a parallel section aft which allows her to be lengthened or shortened as required. 7 sheets of 12mm and 12 sheets of 9mm ply are used in the construction of the basic hull. LOA 20' (6.lm); Beam 7'8" (2.34m); Draft will depend on fit out but the hull excl. skeg will have a draft of 1' (.3m) at a displacement of 3750 lb. (1700 kg) - construction wht. approx. 1700 lb. (771 kg). Power up to approx. 150 hp. |

CEECAN 19
|
CEECAN is a simple river cruiser for outboard power. Her hull may be stretched or shortened to suit and her superstructure and deck layout changed to you own requirements. The drawings give details for the hull and superstructure construction. She may be simply fitted out to your own requirements or we can draw up an internal arrangement for you. The hull has a simple 'V' bottom shape and construction is based upon ply sheets over a simple framework with the bow made up from 2 layers of ply. For most river and canal work a 5 to l0 hp outboard will suffice and she could be altered to take an inboard engine. LOD (Length over deck) 5.79m, 19'; Beam 2.08m, 6'10"; Approx. draft 0.3m,1'; Approx. wht 1400 kg, 3087 lbs. |

RATHLIN 20 MY
|
||
|
Our
Rathlin design is not the type of motor yacht that you would normally see these
days as a new ‘‘modern’’ design. Most new craft of the motor type to
come off the drawing board now, are of the large plastic ‘‘patio door’’
type with maximum space provided in the shortest length possible. I would not criticize
these boats - for what they are and the market that they are aimed at,
they do a good job - especially when trying to get the most for your money out
of marina charges. Rathlin, on the other hand, goes in the opposite direction
and for a 20’ motor yacht simply offers you the most basic of accommodation
with a wc, small galley and 2 berth dinette and an open wheelhouse with a large
aft cockpit. She is every bit traditional 1950’s in style and layout. With
simple elegance she would transport you on estuary and coastal trips without
fuss, and against today’s motor boats, she would stand out as an example of
quality. The drawings show full details for strip planked construction with computer faired mould shapes along with machinery and fit out details. She could also be made with ply/epoxy methods. LOA 20’4’’ (6.20m); LWL 18’4’’ (5.73m); Beam 7’4’’ (2.24m); Draft 2’4’’ (0.70m); Approx. Displ. 1600 kg (3528 lb); Engine 10-30 hp. Additional drawings are now available to construct the Rathlin as a motor sailer. The drawings include details to alter the skeg to make it into a ballast keel and details of the spars, tabernacle etc. Sail Area is 15.89 sq.m (171 sq.ft). and the ballast is 450 lbs (200 kg). IMPORTANT NOTE—included now, with the standard drawings are the mould shapes for a larger version of the Rathlin hull—the hull depth is increased by 4” (0.10m) and the beam by 6” (0.15m) giving an overall beam of 7’10” (2.39m) and an increase in headroom of 6” (0.15m). |

JARVIS 17
|
The Jarvis 17' motor launch has been drawn up for clinker/ply construction - a building jig is made which consists of chipboard mould shapes mounted on a strongback. Ribbands (stringers) are inserted into the moulds at each lap and these help in defining the shape of each plank. The ribbands can be left in the hull if 6mm ply is used for the planking or, be removed as part of the jig if 9mm ply planking is used. The launch has 2 berths in a cabin/cuddy and she has a large cockpit for fishing. Outboards up to 25-30 hp may be used for most purposes although she will take bigger.The bench seats in the cockpit have stowage lockers. LOD 16'11" (5.16m); Beam 6'7" (2.04m); Draft 1'3" (0.38m); Approx. wht 750 lbs (340 kg). |

RUFUS 17
 
|
|
The RUFUS 17' motor boat is a simple rugged craft with jaunty good looks. She
has 3 chines per side and plenty of freeboard and beam, giving her an excellent
carrying capacity and very good stability. She can be made as a simple open
launch, in which case she would make an excellent club boat, or she can have a
wheelhouse/cabin. The standard wheelhouse has bench seating, stowage spaces and
a forward central steering position. With this arrangement there is plenty of
room in the aft cockpit for bench seating. The outboard is housed in a
protective well and she could be fitted with an inboard engine. Construction uses pre-shaped plywood hull panels and girder shapes which can either be stitched and taped together and the plywood frames inserted before finishing the chines in epoxy, or the ply frames and girders can be erected as a framework with square sectioned stringers at the chines and the hull panels then fitted. The 'V' gap between the side of the stringers and the adjacent hull panels can then be filled with thickened epoxy to form a very strong chine join. For those with limited building space and/or budgets, the hull may be built in four pre-fabricated sections for later assembly. She may be fitted out in a variety of different ways to suit the builders' own requirements. LOD 17' (5.18m); Beam 7'2" (2.218m); Average loaded draft 1' 4" (0.4m); Approx. wht 800lbs (363kg) depending on how she is fitted out. |
