| POWER 2 (Mark 1, 2 and 3) | ||||||||||||||||||||||||||||||||||||||||||||||
|
||||||||||||||||||||||||||||||||||||||||||||||
|
|
||||||||||||||||||||||||||||||||||||||||||||||
|
A 21’ x 7’ bigger sister to the Power 1 design using the same easy
construction method and having a similar double chine construction with a flat
bottom panel simplifying her building and producing an easy planing hull form.
The hull, seats and cabin take around 13 sheets of 9mm and 5 sheets of 12mm ply
and she weighs approx. 500 lbs. excl. engine. Both the Power 1 and 2 designs are designed for multi role use either as fast launches or as load carriers and because both have parallel sectional shapes aft, they can be shortened or stretched in length to suit your own requirements. One example of a Power 2 stretched to 24’ has been used as a dive support craft in the Bristol Channel and Irish Sea. With twin 40 hp outboards and fully loaded she could plane with speeds of over 30 knots. |

| POWER 3 | |||||||||||||||||||||||||||||||||||||||||||
 |
Soon after our Power 2.2 left the drawing board, we were asked to extend it and
produce a design which, in a compact form, could accommodate a large aft cabin
with a central wheelhouse and forward dinette. So the beam has been increased to
8’10’’ and the length to 24’7’’ but the same easy riding ‘U’
hull form with double chine has been used. This gives plenty of internal volume
and weight carrying capacity along with high stability. The plans for the Power 3 show details for a forward dinette with a good sized galley and a separate WC and shower compartment. The wheelhouse has an ‘L’ shaped settee which can also form a bunk and the aft compartment has room for a double berth along with a dresser. The drawings show a single 30 hp engine arrangement but twin 50 hp engines could be installed. Construction details are given for both ply/epoxy construction using computer generated hull panel shapes and for ply construction over a framework of ply bulkheads and stringers. LOA 24’7’’ (7.50m); Beam 8’10’’ (2.70m); Approx. Draft 2’6’’ (0.74m); Displ. 6500 lbs (2950 kg). |

| 26' GENERAL PURPOSE WORKBOAT | ||||||||||||||||||||||||||||||||||||||||||
 |
||||||||||||||||||||||||||||||||||||||||||
|
This is a general purpose 26'
workboat with a beam of 8'4". Construction consists of pre-shaped ply
bulkheads and girders which are slotted together. Chine girders are then fitted
and the pre-shaped hull skin then applied. Details are shown for the
construction of the hull and basic deck and superstructure and spaces are given
for the internal fit out which may be altered to suit. She will accommodate a wc,
2 berth saloon, galley and double berth and has a large cockpit/workspace aft.
She is designed to take a couple of large outboard engines. She has a transom
bow above the waterline to increase deck space and for bow mooring. Plans for the hull, deck and superstructure only are available. |

| 21' IJSSEL LAUNCH | ||||||||||||||||||||||||||||||||||||||||
|
||||||||||||||||||||||||||||||||||||||||
| This launch has been
designed for diesel propulsion (10-15 hp) but she can also take steam or
electric propulsion. The layout drawn for her is a simple open thro’
plan with no obstructing bulkheads but she could be fitted out in a
variety of ways—a saloon and/or canopy could be fitted. Construction is Cedar strip plank and the plans give computer faired mould shapes—she could just as easily be built using the clinker/ply method too. The hull has a full bodied wineglass shape and the forward sections are well flaired. She has the capacity to take up to 10 or more crew. |

This is a 22' motor boat with a large cockpit area and comfortable accommodation with 2 large berths, w.c. compartment and galley with dining space. The drawings are originally for steel construction but she could be made out of plywood over a simple framework of plywood bulkheads and girders. She may take inboard engines up to 50 hp. LOD 22' (6.71m); Beam 8'3" (2.52m); Draft 2'7" (0.78m); Approx. wht. 5182 lbs. (2350 kg). Steel hull construction details only are available at present. | ||||||||||||||||||||||||||||||||||||||||||

The Power 225 is based
upon the ‘U’ shaped hull section of our Power series of motor boats.
At present we have the hull panel, frame shapes and construction details
for an aluminium version of this boat—accommodation and fit-out details
are not available bar a simple arrangement sketch but we can either draw
up details or give details from our Power 3 which will act as a good
guide. She is designed for inboard/outboard power and could easily be
built from plywood.
She has been designed to have a large cockpit with open wheelhouse and forward accommodation of 2 berths/settees, wc and galley. LOA 22’ (6.71m); Beam 9’4” (2.85m); Displ. To WL 6615 lbs (3000 kg); Engines up to 150 hp.

| MYLOR 27' STRIP PLANKED FISHING BOAT | |||||||||||||||||||||||||||||||||||||
|
|||||||||||||||||||||||||||||||||||||
| A 27’ Fishing Boat for Mr. J. Clarke - this is a high volume strip planked fishing boat of modern proportions - the drawings are for the hull construction only - the mould shapes are computer faired and her tough hull uses 2 layers of strip plank which can then be sheathed in glass or veneered. Arrangements are shown for the engine and sterngear and internal framing consists of ply bulkheads. LOA 27' (8.24m); Beam 10'3" (3.1m); Displacement to DWL is 8 tons (8.13 tonnes). The skeg arrangement allows her to swing a 33" (0.84m) large prop. | |||||||||||||||||||||||||||||||||||||
| We can supply the wheelhouse/deck construction plans for our Skellig 26 design which can be adapted and used with the Mylor hull drawings, at no additional charge. |

30' IJSSEL LAUNCH |
|||||||||||||||||||||||||||||||||||||||
 |
|||||||||||||||||||||||||||||||||||||||
|
An American client
wanted to produce a replica of the African Queen and saw our Ijssel
launch as offering a craft of similar style—so we increased her length
to 30’ and beam to 8’ (later we were asked to increase the beam
still further to 10’ and this alteration is included with the plans.
The layout is for a simple open arrangement and this may be altered to
suit and she could certainly take a saloon/cabin.
Like her smaller sister, she has well flared forward sections with a full midships section leading into a pretty wineglass transom. The computer faired mould sections and details are given for Cedar Strip construction but the plans include construction details for steel as well. LOA 30’ (9.15m); Beam 8’ and 10’ (2.44 and 3.05m). |

23' PLY CANAL CRUISER |
||||||||||||||||||||||||||||||||||||||||||
 |
||||||||||||||||||||||||||||||||||||||||||
|
This
is a simple ply cruiser designed specifically for canal use on the
UK’s narrow canals. She uses simple ply on frame construction and she
has parallel sections aft which mean that she can lengthened or
shortened easily. The
drawings are for the construction of the hull and superstructure only
and we have a drawing showing two possible options as to how she may be
fitted out. There is space for 2 single berths a dinette that can
convert into a double, separate wc and galley. LOA
22’11”
(6.99m);
Hull beam 6’10”
(2.08m);
Draft around 8” (0.20m); Displ. To WL 4630lbs. (2100kg); Trailing
weight around 3000lbs (1361kg) depending on fit-out. |

| 22' RUFUS MOTOR CRUISER | |||||||||||||||||||||||||||||||||||||||||||
|
|
|||||||||||||||||||||||||||||||||||||||||||
|
The
standard 17’ Rufus plans include the frame and panel shapes for both a
20’ and a fantailed stern version but we have been getting many
requests for a slightly longer version and so we jumped at the chance to
draw up a completely new set of plans when asked to lengthen the
standard design. The
22 footer has the same rugged displacement hull type as the smaller
version with the exception that an additional chine has been added. The
construction is basically ply panel over a ply eggbox type framework but
details are also given for stitch and tape and the combi-stringer
methods. She
may be powered by an outboard in a well but the drawings are based on a
20 hp inboard unit and the standard arrangement is for V berths forward
with space for a wc and with a galley in the wheelhouse and an aft
cockpit. However, like the 17’ version, she could be fitted out in a
number of different ways with layouts to suit individual requirements. LOD
22’ (6.71m); Beam 8’1” (2.46m); Draft 2’ (0.61m); Displ. To WL
3947lbs (1790kg); Approx. weight 2756 lbs. (1250kg). |

26' IJSSEL LAUNCH |
||||||||||||||||||||||||||||||||||||||||||
|
||||||||||||||||||||||||||||||||||||||||||
|
It
had to happen of course—having designed
21’ and 30 Ijssel launches, someone would want something in
between and here it is. The hull is very much of the Ijssel high volume
stable model with plenty of space for whatever internal arrangement you
need at this length. In this set of drawings though, the client asked
for a simple forward cabin. This gives convenient shelter to sit and lie
in or to arrange a small wc. The cabin could easily be extended and
could of course be used on the 21’ and 30 Ijssels. Like
her sisters, construction is for Cedar strip plank and whilst the
drawings give details for diesel machinery installation, she could take
steam or electric. LOD
25’10” (7.87m); Beam 8’ (2.43m); Draft 2’ 7 1/2” (0.80m);
Displ. To WL 6615lbs (3000kg); Approx. weight 3750 lbs. (1700kg). NOTE - Also see the Golden Bay Launches in our Steam Section. |

| HOWTH HEAD 22 | |||||||||||||||||||||||||||||||||||||||||||
|
|
|||||||||||||||||||||||||||||||||||||||||||
|
The Howth Head is a plywood version
of the steel Lambay Island design. Like the Lambay, she is
a 22' motor boat with a large cockpit area and comfortable accommodation with 2
large berths, w.c. compartment and galley with dining space in the cockpit.
Construction is ply hull panels over a framework of plywood bulkheads/frames slotted onto a ply fore and aft girder. the chine seams are either conventional wood stringers or expoy and tape. She may take inboard engines up to 50 hp.
|
|||||||||||||||||||||||||||||||||||||||||||

|
This is a rugged steel
workboat/fishing boat for coastal and offshore use. She has a large cockpit and
enclosed wheelhouse with space below for a simple wc and/or galley.
The steel hull panel shapes are given so that the hull can be constructed either by tacking the plates together over wood moulds and then fitting the framework or by assembling the full framework first and fitting the panels over the top. Note - for a wood version of the Saltee Island, see the next design below. The hull has a double chine U/V bottomed shape giving an easy riding displacement hull that can be fitted out in a number of different ways. |

|
The Skellig 26 is a wood version of
the Saltee Island. She has the same rugged hull design for use as a workboat/fishing boat for coastal and offshore use. She has a large cockpit and
enclosed wheelhouse with space below for a simple wc and/or galley.
The plans give details for the hull to be built in strip Cedar with a round bilge hull and a plywood hull which is multi-chined. In both cases construction is rugged and very strong for work use. The hull has a U bottomed shape giving an easy riding displacement hull that can be fitted out in a number of different ways. The hull could also be fitted out as a rugged pleasure craft with larger wheelhouse/forward cabin. |

| STOUR 23 | ||||||||||||||||||||||||||||||||||||||||||||||||||
 |
||||||||||||||||||||||||||||||||||||||||||||||||||
|
The Stour 23 has a simple 'V'
bottomed hull form giving an easily driven shape that is also faster to build.
Construction starts with a simple arrangement of plywood frames and bulkheads
slotted together on a plywood central girder. Chine stringers are then fitted,
planned up and the ply hull skin fitted - or the pre-shaped hull panels can be
fitted to the framework and the chines finished with epoxy/glass.
The Stour is basically a fishing boat so she has a large aft cockpit and a forecabin which has 2 berth/settees and space for a small galley and wc. Two options are given for the transom/engine arrangement - either the outboard can be fitted directly to the transom with a slopped well in front of it or the outboard is fitted further forward so that the outboard is fully protected by the hull. The hull could be fitted out in a number of ways - with an aft cabin etc - the arrangement above is the one shown on the plans.

The Jarvis 21 is a fast
clinker motor launch designed for use in Key West, Florida.
Construction is for clinker ply over mould shapes erected onto a strongback. She has ply bulkheads or solid wood frames which can be used instead of the moulds and left in the hull permanently during construction. The layout given on the drawings is a typical open plan Key West layout with possible fish storage forward and twin athwartships seat benches. She could take 8 people comfortably and either have a wheelhouse or Bimini top.
