STEAM & ELECTRIC LAUNCHES
OVER 30' IN LENGTH
(PLYWOOD & CEDAR STRIP)

 

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 5 designs - all are round bilged in hull shape - 4 are specifically for strip planking and 1 which is designed for conventional carvel planking but which could be strip planked.

 

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.
Speed and power requirements are also based on feedback and estimates and are for guidance only - actual speeds attained will depend on loading etc.

Amaryllis 30
The 30’ Amaryllis was commissioned by Mr. William Fuller to replace his 22’ steam launch. The new launch will be built by the International Boat Building College in Lowestoft using conventional planked methods. She uses a 25 hp steam unit by J. Alex Ritchie.
She is of a size which allows a variety of different layouts to be used. The standard plans include a computer faired lines plan and offsets, construction details for conventional planking and an arrangement plan for the layout shown. We can generate drawings for strip or cold moulded construction with computer lofted mould drawings allowing the builder to get straight down to construction. LOD 30‘(9.14m); Beam 6’8‘‘(2m); Draft 3’1‘‘(.95m); Displ. 3.5 tons (3555kg).

EDWARDIAN 30
This steam launch has been designed for a client in South Africa and will be used for educational trips in an area of great natural beauty. She is a development of our Edwardian range and uses strip plank construction techniques on computer faired mould shapes.
Power comes from a 15 h.p. steam plant although she can accommodate both electric and internal combustion engines. The layout is divided roughly equally between a saloon which has a settee dining area, galley and w.c. and a forward open cockpit area. The layout may be changed to suit. Both air draft and water draft have been kept to a minimum to extend her inland cruising capability. LOD 30' (9.15m); Beam 7'6" (2.29m); Draft 2'7" (0.8m); Approx. weight 6615 lbs. (3000 kg.).
The pictures are of an Edwardian 30 by Mike O'Shea in Australia.

30' SISKIN

With the number of hulls modeled on our YachtCAD system, this launch demonstrates our ability to quickly design a craft which embodies features from a number of other craft in order to meet the rquirements specified by a particular client and to easily access the new craft's hydrostatic data from known craft. In this case the client required a launch with plumb stem and transom stern with a narrow beam (for use on our narrow gauge canals) and large carrying capability on a length of 30'. He liked the stem of our Linnet design and some of her other characteristics and we therefore used her as the model for this new design.
The drawings give details for the construction of a strip planked hull with computer faired mould shapes. If required, we can give details for the construction and fit-out of a saloon, steering system and engine installation from one of our other designs. LOD 30' (9.15m); Beam 6'9" (2.06m); Draft 2'3" (0.68m).

38'6" LINNET RIVER LAUNCH
Linnet 38Linnet 38
This was a commission for David Graham Boatbuilders at Wargrave on the Thames for an electric river launch. The hull is based upon our Edwardian series with a graceful counter stern but instead of the clipper bow, a vertical stem was called for. She has the displacement volume to carry extensive banks of batteries low down in her bilges where their weight acts as ballast. She could equally be fitted out with a steam engine and boiler and she would have plenty of space for large bunkers.
The general arrangement drawn has a spacious cabin with a galley and w.c. compartment and a large canopied forward cockpit. The original launch was built using strip plank techniques and therefore the computer faired sectional mould shapes, stem and stern profiles and the building jig drawing are available along with a general arrangement drawing and recommendations for scantlings. Full construction and fit out details for the amateur builder can be drawn up to suit individual requirements. LOD 38'6" (11.59m); Beam 6'10" (2.08m).
The drawings also give details for a multi-chine (3 chines/'V' bottom) plywood version.

ADDITIONAL DETAILS FOR THE LINNET

We now have drawings which give the hull/superstructure and fit-out drawings for a “Flat Top” version of the Linnet launch—these drawings are based on the  38’6” (11.59m) x 9’10” (3m) beam version of the Linnet and provide a layout which has 4 berths (double in fore cabin), galley and dinette in the deck cabin along with a shower and wc. The original will be powered by two electric pods but there is plenty of room for diesels plus generator etc under the deck house sole.

The additional superstructure and fit-out details for this “Flat Top” version cost an additional £135 incl. VAT (UK/EU); £115/$184 (US/Elsewhere) - a GA sheet is sent out with the standard study plan at no additional charge.

EDWARDIAN 50
The Edwardian 50 has been designed for canal and inland river use. She has a beam of 7’6’’ which allows her to navigate much of our inland waterways and a height (air draft) which will let her get under most bridges. Her construction drawings are for strip planked construction and show computer faired mould shapes for the building jig. The Cedar hull is intended to be sheathed inside and out giving a stiff shell. To keep her underwater draft low, her propeller works inside a tunnel.
The construction method can be changed and she could, for instance, be made from multi-chine plywood. She may be fitted out in a variety of ways but the standard layout shows a saloon with a raised ‘clerestory’ roof with a large forward open cockpit/engine room, aft cockpit. The saloon houses an enclosed wc compartment, galley and four settee/berths.
LOD 48’9’’ (14.85m); LWL 40’2’’ (12.22m); Beam 7’6’’ (2.29m); Draft 2’2’’ (.66m); Displacement 7.73 tons (7.85 tonnes).  Construction plans presently exist for the hull, decking, superstructure.
