How to Build a Dolphin D25 Fisher J2543

Ever thought about building your own boat but have been frightened off by the thought that you may not have the time , the ability or money? The odds are that you are terrified of the dreaded process of lofting out the plans from the complicated pile of papers and drawings that you normally get when you buy a set of boat plans! 
Have you heard about the Digimaser 3 Eazy-build method of boatbuilding? It is a series of innovative small craft that have been named 'The Dolphin Series'. They are cheap, robust, simple to build, with minimal plans that importantly, do not involve lofting and have no frames at all! The latest in the line will knock your socks off. It's the D25 and is a great dive/fishing boat that can be built in a garage in under six months!
They are simply constructed with the 'stitch and glue' methods that anyone with a minimal of commonsense can achieve. The design materials are NZ/Australian standard exterior ply, epoxy resin, glass tape and bi-axial glass cloth that ranges in weight from 200 gms to 600 gms, all materials are easily available everywhere in Australia and worldwide.
For the uninitiated, the stitch and glue method is a method of boatbuilding that allows a boatbuilder to build a boat very quickly at minimal expense. Boats up to forty feet long have been built using this method and are in use worldwide today.

The specs range from 12' dinghy, the 16' gaff sailing boat, the centre console 16' for keen anglers. They then progressed progressed to the 19' sailing yawl, that has two masts and is a camping/day/weekender that is easily trailerable.

The newest of all, the D25, is causing a sensation for its ease of build and how powerful the stitch and
J2543 glue method is becoming THE method for getting a boat builtfast!

The plans, involve a simple X/Y co-ordinate system that does away with the painful process of lofting... a nightmare for first timers and a pain generally for all concerned. The sheets of ply are drawn up into suitable size squares, the co-ordinates supplied with the plan copied to the squares and then the points joined together with a bendy  J2543 batten.

This patented method is almost a 'join the dots' method of cutting out the shapes required from plywood that have been pre-glassed and faired whilst lying flat in the garage or workshop.

The United Nations, interestingly, during the crisis in East Timor, chose the design to be taken for the  J2543 Timorese Fishermen to use as a blueprint for their new generation of fishing boats that their villages are supplied with. . A typical 16' Dolphin can be assembled, stitched and glued and finished in approximately 40 hours work, a matter of 3 or 4 weekends. A 16' Dolphin is cut out in a weekend. The
transponder chip key mitsubishi  fastest time we know of for a 12' Dolphin build was in 24 hours by a team of lads from the Wooden Boat Club at a Brisbane 'Down by the River' expo some years ago, and it was presented to a lucky draw winner who actually rowed it up the river on Sunday!
