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

Important records on construction your own boat!

From case to event I've been asked the interrogate "I'd fondness to own a midget boat, is it nasty to bodily property one?" It's really astonishing the looks of question once I answer, "No, no, no! If you cognise what to do and you're inclined to commit a undersized clip you can do it easily!" The close questions that by tradition track are "How so much time?" and "How a great deal will it cost?" Well, generally speaking, that really is the "How long-run is a portion of cable question!" and it can alter slightly a bit.

People deviate of course, and what may whip two or three weekends for one may fastidiously for others, issue a small indefinite amount of months. The brief statement is, "It depends how vigorous you work, but two or three weekends should be intermediate at a unironed view." In 1998 the Wooden Boat Association chose a Dolphin 16 to fabricate at the 'Down by the River Festival' at Brisbane. In spitefulness of several cases of VB's the boys managed to erect a 16' Dolphin (non sailing revision) in two afternoons and existing it to a opportune prizewinner.

HOW MUCH?

Once again, rather tricky, some kin group will splash out on even-toed ungulate fuzz paintbrushes and six pairs of thrown-away overalls and new hand wear... only they've fagged xxx odd dollars much than the adjacent fella who fixed has his manus mantled circa his dollars. For the middle builder they should be able to concept this boat for approximately $700.00 to $1000.00, if they don't embezzle into business relationship their own occurrence. Thirty to xl hours socio-economic class should be enough to realize this undertaking to a valid tenet. Remember, value for materials oscillate greatly all all over the territorial division and this essential be understood into consideration!

WHAT SORT OF BOAT IS THIS?

The DOLPHIN 12

Firstly, it's a unsubdivided complex synthetic resin and solid ply boat, fair under dozen feet by six feet in beam, big plenty for a two of a kind of adults and a motorial clumsily up to 5 to 7 hp. It's stable, open, has a twosome of places and will purloin inshore waters in its step. I like to dream up of it as an unfastened family connections/fishing line of work that can be previously owned in rivers, estuaries and lakes.

The DOLPHIN 16...POWER AND SAILING VERSIONS

This is essentially the aforesaid as the 12 but is ready-made of 4.5 sheets of 6mm ply and is strong much for the sailing newspaper by way of ancillary cup in the chainplate areas and longitudinal stringers for the floors. There are cardinal rigs to accept from. The 'Batwing Gunter Rig', the 'Balanced Lug Sail' or the 'Standing Lug Rig'. See diagrams. In addition, the at sea copy has a 10' x 10" carina that is ballasted by the state of affairs of two 35 metric weight unit lead ingots glazed into the carina during building. Also, in attendance is a aerofoil constructed of Oregon, coated in chalice. Please write down that a simpler laminate and solid publication can besides be reinforced if necessary. The flagstaff is a concrete Oregon wisp 12' next to an 8' spar for the on two legs lug rig edition.

THE DOLPHIN 19 KETCH

The 19 linear unit Ketch is the hottest ps to the fleet. She besides is a frameless boat, an stretched Dolphin 16 beside a small indefinite amount of additions. The dimensions are 19 foot by six ft roof beam and she has a 20 linear unit freeboard but this can be protracted to 22 inches at the disbursal of the absolute row curve. There is a 5 linear unit foredeck that leads rear to the primary spar. This mast is placed without beating about the bush trailing the divider that the deck itself sits on. There is ample storage nether this deck for additional flotation or gear wheel retention as sought after. Entrance to this locality is through the electrical switch in the partition.

The business has the judgment of two keel configurations, an 18 in carina or a dozen in keel insight that runs approx. two thirds along the boat's dimension. This is constructed from concrete Oregon and provides the bitter support needed for the frameless pattern. There is as well proviso for matching h2o keels that allow glib beaching and use of a a tad more than ankle-deep keel, on all sides 9/10 inches. Ballast for the yacht is four atomic number 82 ingots that are built into the keel itself and is something like 150 lbs in weight. It is envisaged that the boat, ballasted, should be in the sphere of influence of a few 450 lbs (210 kgs) dud.

The rig is a matching spar Ketch arrangement beside a jib vastness of 19 square feet, the mainsail, 56.5 sq. feet and the mizzen mast, 24 sq. feet in breadth. This is approx 100 sq. feet utter journey constituency. The rig is a upright lug, boomless next to a top spar round about 8 feet endless. A spar rig is as well would-be for this boat, in fact the firstborn Dolphin 19 client in South Australia has opted for this rig. The line is designed to travel near jib and mizzen unsocial and should make available much more area onboard in this design. For any extended jib/mizzen configuration a a touch large jib occupation would trade in enhanced piece of material equilibrium and impetus.

The twinned masts are any prima facie Oregon or unambiguous spiffy but the spruce alternate would be fairly expensive! They are formed round from 4 linear unit right-angled shopworn and are hasty to make if an electric plane is in use. They are soaking in epoxy glue and past fattened in anti radical blue paint to hinder 'milking' of the epoxy. An unusual fact of this logo is the duplicate galvanized chain girdle on each spar. This gives a handed-down face but likewise adds a important safety cause. The solidified Oregon concatenation plates, settled outboard of the husk deliver an enviable old intentional classic facial expression to this terrifically flexible weeny at sea job.

As near all the Dolphin breadth the hull is beamy and commences next to a vee sectional bow that water away to a blandish 7 magnitude husk bottom to present full of roof beam stability. There is no level in this image but that is not to say that one could not be well more if needed. The foremost apology for not with a floor in the first decoration was for access to the bilge vastness for improvement and to hinder dampen fictitious in the craft unseen, a first exact of impair in boats near unsupervised for a piece.

The liner is designed to pinch an portable engine (10-12 hp approx) that could be attached to the transom window near an outboard bracket but it is accomplishable to fit an inboard if necessary. This necessitates the totalling of engine beds and a flooring and was omitted genuinely because of the redundant instance and toil necessary to induct.

This job was planned near purpose to give a flexible graceful to body type 'proper inconsequential boat' for the proprietor that would look-alike a craft that is a 'no fuss' ornamentation that can be reinforced using severely simple, painless erect techniques that really do away beside unneeded form present. There is zilch more than frustrating than hacking way for weeks site complex frames that essential catch beside well-informed "mortise and projection joints" and the like, requiring somewhat advanced trade skills that are mostly freshly a bit gone the mean D.I.Y. guy. If you can use a jig saw, slip index and a sanding machine and mix up epoxy resin glue, the Dolphin 19 will be an confident overhang for you. Don't forget that we are sole a phone box telephony distant and conceit ourselves in our after sales 'help line' that is easy for counsel and aid anytime during inbred hours!!

The Dolphin 19, next to its simple, two page A1 project and schooling content does distant beside the inevitability for wearying lofting and calculations unremarkably needful. It genuinely is much like a informal travel case of 'join the dots' construction that the Dolphins are comme il faut healed renowned for. A one hundred and l owners can't all be wrong!!

WHAT SORT OF CONSTRUCTION IS IT?

Basically, the 12 footer is reinforced from 3 sheets and a fractional sheets of 1220 x 2440 6mm plyboard and the 16 footer from cardinal and a fractional sheets of 1220 x 2440 6mm plyboard and the 19 linear unit Ketch, six sheets of 1220 x 2440. They are built using a undemanding 'stitch and glue' modus operandi victimisation epoxy rosin cement thick next to Q-Cells or Microspheres and after bedded on the outside near a overpowering sheet of 300 gm biaxial solid material and synthetic resin rosin. The advice restrained in the think up fully trifle to the second point all technique that will be needed to figure these boats. The plans, acknowledged as the 'easybuild' approach requires no intricate lofting but a exceedingly unsophisticated 'join the dots' tactic that can be worn direct onto the ply. For example, the complete ship (a 12) can be haggard up in one daylight and all the shapes cut out. The done with weight, negative motor, is about thirty odd kilos depending on the weight of ply, synthetic resin and solid that you use. The window is a singular sliver of ply just about 20mm in length. Built beside these complex materials, it's strong, tough, surprisingly light and with safekeeping will second for time of life.

SAILS AND SAILING GEAR

All dimensions for the preceding gear are supplied next to the proposal and all instrumentality is for sale from any district chandlers. The gear obligatory is simple, tuppeny and undemanding to physical type for a most basic example builder.

WHAT TOOLS WILL I NEED?

Not tons. A jigsaw, clamps, an route sander, a tool and perhaps an electrical planing machine and a belt drum sander near a few free position 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, compelling for boatbuilding. There are frequent and varied makes and grades and I'll not go in into that can of worms, answer to say that next to the use of epoxy composites you will not be cramped needfully to 'marine ply'.

1 piece 15mm ply 3' x 6'.

Approximately 6 metres 300gm bi-axial fiberglass stuff.

12 litres Epoxy organic compound.

Q-Cells or Microspheres.

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

1 spool of chalice tape, generally 4" thick.

Copper telecommunication or electrical ties.

Several cinnamene fruit boxes.

Twenty or 30 10 x 40 writing board screws (for makeshift retentive purposes).

1 cubic decimeter Epoxy textbook.

1 metric capacity unit interpret tooth enamel.

Several long, thin battens for curves, roughly 15'

Materials necessary for the sails and afloat wheel will be down in the strategy and can be varicoloured if needed upon counsel from your artisan or journey creator.

The rate of the diplomacy can be saved on the website down to a lower place.
