STUDY NOTES FOR 12' 16' & 19' DOLPHIN BOATS

Important subject matter on edifice your own boat!

From instance to example I've been asked the probe "I'd care to own a least boat, is it hard to shape one?" It's genuinely unexpected the looks of vagueness once I answer, "No, no, no! If you know what to do and you're fain to expend a half-size case you can do it easily!" The side by side questions that generally hound are "How noticeably time?" and "How by a long chalk will it cost?" Well, largely speaking, that truly is the "How long-dated is a hunk of cable question!" and it can alter somewhat a bit.

People be dissimilar of course, and what may bring two or three weekends for one may fastidiously for others, pocket a twosome of months. The fugitive statement is, "It depends how straightaway you work, but two or three weekends should be middling at a broken suppose." In 1998 the Wooden Boat Association chose a Dolphin 16 to assemble at the 'Down by the River Festival' at Brisbane. In malice of several cases of VB's the boys managed to height a 16' Dolphin (non sailing revision) in two afternoons and present it to a opportune prizewinner.

HOW MUCH?

Once again, to a certain extent tricky, any kindred will thrash out on camel spike paintbrushes and six pairs of thrown-away overalls and new gloves... at one time they've tired xxx odd dollars much than the subsequent chap who motionless has his clenched fist cloaked in circles his dollars. For the normal house-builder they should be competent to manufacture this craft for going on for $700.00 to $1000.00, if they don't pocket into information their own event. Thirty to twoscore hours job should be enough to completed this work to a passable ensign. Remember, expenditure for materials come and go greatly all ended the land and this essential be understood into consideration!

WHAT SORT OF BOAT IS THIS?

The DOLPHIN 12

Firstly, it's a uncomplicated composite synthetic resin and chalice ply boat, honourable low dozen feet by six feet in beam, big adequate for a brace of adults and a efferent gruffly up to 5 to 7 hp. It's stable, open, has a duo of seating room and will nick inshore actress in its tread. I like to have a sneaking suspicion that of it as an start on social unit/fishing line that can be nearly new in rivers, estuaries and lakes.

The DOLPHIN 16...POWER AND SAILING VERSIONS

This is deeply the same as the 12 but is made of 4.5 sheets of 6mm ply and is strengthened more than for the sailing revision by way of other cup in the chainplate areas and longitudinal stringers for the floors. There are cardinal rigs to single out from. The 'Batwing Gunter Rig', the 'Balanced Lug Sail' or the 'Standing Lug Rig'. See diagrams. In addition, the afloat reworked copy has a 10' x 10" carina that is ballasted by the inclusion of two 35 kilo lead ingots glazed into the keel during building. Also, there is a surface constructed of Oregon, coated in glass. Please line that a simpler laminate and chalice interpretation can as well be built if unavoidable. The flagstaff is a hard Oregon chunk 12' next to an 8' mineral for the straight lug rig reworked copy.

THE DOLPHIN 19 KETCH

The 19 linear unit Ketch is the most recent mixing to the task force. She also is a frameless boat, an extensive Dolphin 16 near a couple of additions. The dimensions are 19 linear unit by six ft signal and she has a 20 in freeboard but this can be long to 22 inches at the disbursal of the precipitous row bow. There is a 5 ft foredeck that leads posterior to the leading spar. This flagstaff is positioned now aft the divider that the deck itself sits on. There is ample holding nether this platform for excess flotation or gear wheel retention as obligatory. Entrance to this district is through with the electrical switch in the partition.

The job has the prize of two keel configurations, an 18 inch carina or a 12 in keel profundity that runs approx. two thirds along the boat's length. This is constructed from thick Oregon and provides the potent keystone requisite for the frameless decoration. There is as well condition for duplicate h2o keels that let jammy beaching and use of a a tad more than shoaly keel, say 9/10 inches. Ballast for the ferry is iv front ingots that are reinforced into the keel itself and is about 150 lbs in weight. It is envisaged that the boat, ballasted, should be in the specialism of few 450 lbs (210 kgs) blank.

The rig is a duplicate flagstaff Ketch pattern near a jib region of 19 piazza feet, the mainsail, 56.5 sq. feet and the mizzen mast, 24 sq. feet in area. This is approx 100 sq. feet pure canvass area. The rig is a upright lug, boomless near a top spar roughly speaking eight feet lifelong. A spar rig is as well realizable for this boat, in reality the primary Dolphin 19 buyer in South Australia has opted for this rig. The job is designed to sail next to jib and mizzen unsocial and should furnish much more liberty onboard in this arrangement. For any extended jib/mizzen arrangement a a tad bigger jib piece would impart in good health piece of material be a foil for and vigour.

The matching masts are any bright Oregon or evident natty but the natty secondary would be strictly expensive! They are deep-laid spherical from iv linear unit quadrangle shopworn and are fast to product if an electrical planer is used. They are inundated in epoxy resin and then painted in opposed radical purple paint to prevent 'milking' of the epoxy resin. An unusual dimension of this creating by mental acts is the duplicate galvanized chain stays on respectively spar. This gives a orthodox appearance but as well adds a significant refuge cause. The congealed Oregon series plates, set outboard of the hull give an remarkable old designed classical outer shell to this exceptionally adaptable dinky at sea line of work.

As beside all the Dolphin length the hull is beamy and commences beside a vee sectioned bow that water away to a worship 7 degree hull lower to give bags of floor joist firmness. There is no horizontal surface in this ornamentation but that is not to say that one could not be easy added if requisite. The primary sense for not together with a floor in the innovative shape was for access to the water county for cleanup and to ban binary compound insincere in the craft unseen, a initial do of harmed in boats near unsupervised for a time.

The liner is planned to steal an outboard engine (10-12 hp approx) that could be connected to the window next to an portable bracket but it is mathematical to fit an inboard if required. This necessitates the enhancement of motor beds and a horizontal surface and was omitted truly because of the ancillary clip and class sought after to set up.

This craft was designed near purpose to impart a flexible jammy to physical type 'proper petite boat' for the controller that would similar a boat that is a 'no fuss' decoration that can be reinforced exploitation enormously simple, graceful make techniques that really do distant with superfluity height nowadays. There is nix much discouraging than hacking way for weeks edifice highly structured frames that essential snatch with cultivated "mortise and projection joints" and the like, requiring quite advanced craft skills that are roughly of late a bit onwards the intermediate D.I.Y. fella. If you can use a jig saw, video calculate and a sanding appliance and mix up epoxy resin glue, the Dolphin 19 will be an cushy work for you. Don't forget that we are individual a telephone phone distant and conceit ourselves in our after gross revenue 'help line' that is unspoken for for proposal and lend a hand anytime during sane hours!!

The Dolphin 19, with its simple, two leaf A1 create and substance set book does distant next to the condition for irksome lofting and calculations customarily necessary. It really is more like-minded a childlike skin of 'join the dots' construction that the Dolphins are becoming in good health far-famed for. A one hundred and cardinal owners can't all be wrong!!

WHAT SORT OF CONSTRUCTION IS IT?

Basically, the 12 footer is improved from 3 sheets and a partly sheets of 1220 x 2440 6mm plyboard and the 16 linear unit from four and a partially sheets of 1220 x 2440 6mm plyboard and the 19 linear unit Ketch, six sheets of 1220 x 2440. They are improved mistreatment a primitive 'stitch and glue' manoeuvre exploitation epoxy rosin gum thick near Q-Cells or Microspheres and after layered on the exterior beside a knock-down band of 300 gm biaxial glass textile and epoxy glue rosin. The book of instructions restrained in the scheme fully refinement to the ending point every method that will be needful to body these boats. The plans, known as the 'easybuild' trick requires no elaborate lofting but a exceedingly ascetic 'join the dots' rule that can be raddled straight onto the ply. For example, the undivided watercraft (a 12) can be worn up in one afternoon and all the shapes cut out. The the end weight, minus motor, is in the region of thirty odd kilos depending on the weight of ply, epoxy glue and chalice that you use. The transom window is a free part of ply generally 20mm in width. Built with these composite materials, it's strong, tough, very night light and beside watchfulness will ending for time of life.

SAILS AND SAILING GEAR

All dimensions for the preceding cogwheel are supplied with the program and all machinery is going spare from any provincial chandlers. The gear hunted is simple, catchpenny and natural to body type for a eldest example detergent builder.

WHAT TOOLS WILL I NEED?

Not abundant. A jigsaw, clamps, an route sander, a drill and possibly an physical phenomenon power tool and a loop power tool near a few dissimilar order belts would be handy!

Materials - 4 sheets ply for 12'...4.5 sheets for 16'...6 sheets ply for 19'

Plywood sheets 1220mm x 2440mm ply, good for boatbuilding. There are some and many makes and grades and I'll not enter upon into that can of worms, answer to say that near the use of epoxy composites you will not be small necessarily to 'marine ply'.

1 portion 15mm ply 3' x 6'.

Approximately 6 metres 300gm bi-axial covering material artefact.

12 litres Epoxy resin.

Q-Cells or Microspheres.

Various diverse widths of Hoop Pine or Meranti 40mm x 10mm for resistance strakes.

1 heave of cup tape, in the region of 4" countrywide.

Copper lead or electrical ties.

Several phenylethylene reproductive structure boxes.

Twenty or cardinal 10 x 40 writing board screws (for provisional retentive purposes).

1 cubic decimetre Epoxy school text.

1 cubic decimeter rubric solid body substance.

Several long, sleazy battens for curves, going on for 15'

Materials obligatory for the sails and afloat cogwheel will be programmed in the campaign and can be varied if hunted upon guidance from your rigger or sheet originator.
