Didi 40cr2 Kit from Exocetus Marine

Exocetus Marine in UK develops and supplies kits for our radius chine plywood catamarans, with kits produced for the Dix 470 and DH550 cats. A kit is currently in development for the new Dix 430 catamaran. The kits are very comprehensive and can be customized to each customer's needs, from basic bulkhead kits through to inclusion of whatever equipment and materials the particular builder would like to be delivered in the shipping container with the pre-cut plywood and other timber.

I have written about the Exocetus Marine kits in earlier posts on this blog, from when development first started in 2012. They have come a long way since then, under the expert hand of owner Kevin Bream.

The DH550 catamaran "Valerie", built in Durban, South Africa, and in charter service in the Seychelles, was built from a very comprehensive kit supplied by Exocetus Marine, which included solid timbers, epoxies, engines, hardware, electronics, porthole frames etc.

The Dix 470 catamaran "Marram", being built in Australia, is a big amateur project. The components have all been cut from CNC cutting files developed and supplied by Exocetus Marine.

Exocetus Marine is now expanding their range in a new direction. This harkens back to my origins in radius chine plywood designs with my Didi 38 prototype "Black Cat", which has spawned a large and expanding range of designs from 15ft to 55ft, spanning both monohulls and multihulls. The Didi 38 design itself expanded to the Didi 40cr and, most recently, the Didi 40cr2. It is the Didi 40cr2 that is the newest project by Exocetus Marine.

As with their catamaran kits, Exocetus is developing a very comprehensive kit for this first expedition into monohulls. In doing so they have transformed my CAD drawings into a complete 3D model before extracting the components for cutting by CNC then testing for accuracy of build. In doing this they are building the boat as well, enabling preparation of complete building instructions to guide those who will follow to build the Didi 40cr2 for themselves.

These photos are a few from the build record to date.

Bulkhead example, with jigsaw joints, doublers fitted around stringer slots.

All parts are referenced for identification and assembly instructions.

Bulkheads set up on the building stocks.

Cockpit structure installed, bracing the whole structure.

Backbone with bevels and scarphs pre-cut.

Pre-cut opening for propeller shaft log.

Laminated keel floors.

Keel floors installed through backbone structure.

Stringers being installed. This is a tangent stringer, with a doubler on the outer face for joining the radiused skin above the stringer to the flat skin below.

Hull side panels jigsaw-jointed at ends of sheets.

Example from the interactive building manual for the DH550 catamaran. A similar manual will be supplied with the Didi 40cr2 kit.

Check back to this blog occasionally. I will update here on progress of the kit development and the construction of their boat.

Of Camels, Boats, Dunes and Things

We all learn in school about the "ship of the desert", the much maligned camel. These animals and their owners are totally adapted to living on and cruising the undulating surface of the desert. We also know of the traditional boats of the Arab world, the dhows that are seen in both power and sail versions. These are very seaworthy boats and have done extensive voyages.

Not heard of nearly as often in that part of the world is the construction of a modern high performance yacht. Such a construction project is the Didi Mini Mk3 of Hugo Vanderschaegh, proceeding apace in Dubai. This is a Mini 650 racer that is built from plywood. Designed primarily for amateur builders, this one is being built by professionals. The photos below show the hull with all flat sheets fitted and the radius skin starting, through to hull turning.

This boat is being built from a CNC kit that was supplied by our Cape Town kit supplier, CKD Boats. They are able to supply kits for most of our radius chine plywood designs as well as the classically-styled lapstrake designs.

They turned Hugo's hull right-way-up last week and recorded it on time-lapse video. They accomplished it with plenty of helping hands and no mechanical equipment. This is a wide boat, at 3m beam, so it towers above the men providing the muscle power. It worked in their situation with lots of hands but "don't try this at home". For the average builder it is better and safer to use mechanical equipment to raise one side under control then lower it again on the other side.

You can see more of his Didi Mini Mk3 project on Hugo's website and follow future progress. Also visit our website at http://dixdesign.com/ to read more about our range of designs and available kits for our plywood boats.

CNC kits for Didi 28

A few posts back I announced the latest addition to our radius chine plywood Didi range, the Didi 28. This design was commissioned by an amateur builder in Greece who wanted a maxi trailer-sailer, along the lines of the Didi 26 but with more space and comfort.

Panel files are now complete for the bulkheads and all of the skin panels for hull, deck, cabin and cockpit. They can be cut by any of our normal plywood kit providers, who are listed on our kits page. The panel files will be supplied to whichever of those suppliers you choose to cut it for you. There are contact links to all suppliers on that page.
