Boat Plans Aluminium Australia | Kit build Dix 470 Plywood Catamaran

Boat Plans Aluminium Australia

Assembly of the prototype Dix 470 plywood kit by Exocetus Yachts in UK is progressing nicely. This is the second hull, with improvements added into the kit since assembly of the first hull. These photos were sent to me by Exocetus.

Exocetus is able to use more advanced methods than would be used by amateur builders but the kit is set up to allow those with more basic facilities to produce comparable quality. Being the developers of the kit, they have cut all of the components themselves on their own CNC equipment. They also have a large press that they use to join multiple sheets of plywood into long panels or other large components, like bulkheads, cabin soles etc.

Sheets being joined into long hull panels by means of a press.

This long outboard hull panel was pre-assembled into one large piece before installation.

Inboard hull side fitted, with horns for major bulkheads projecting into the bridgedeck area.

Bottom panels were fitted installed.

The side panels were glued into longer lengths for convenient assembly with the equipment available to Exocetus. For my own projects and more primitive methods, I prefer to assemble skin panels in single-sheet lengths. This leaves considerably more scope for adjustment during installation to remedy any possible errors that arise due to builder error. The bottom panels were installed in single-sheet lengths, to allow accurate fitment at the centreline joint.

In the last photo above, the jigsaw joint was aligned using a strip of plywood, wrapped in plastic tape, as a temporary butt-strap. A short screw into each lobe of the jigsaw pattern ensured accurate assembly and held the joint securely until the epoxy had set.

Wood Boat Plans And Kits | Cape Cutter 19 Launch in Cape Town

Wood Boat Plans And Kits

Nick Kulenkampff, of Cape Town, bought plans from us in November 2013 for the Cape Cutter 19, to be built in lapstrake plywood. I only received one question from him and that was on choice of plywood for the build. A few days ago I received another email from him, with launch photos attached. He launched his boat, named "Mimi", at Royal Cape Yacht Club, in February.

In his email, Nick said "thank you for a beautiful design and also for a set of plans that were spot on. I thoroughly enjoyed the entire process." From the photos it appears that he made a pretty good job of the build, which was also quicker than most at about 15 months.

This boat is available in GRP from Cape Cutter Yachts in UK. It is the smaller sister to our popular Cape Henry 21 design.

Here are some of Nicks build photos, with explanations

Making bulkheads. These are cut from full-size Mylar patterns, included in the plans.

Transom, laminated from multiple layers of plywood.

Bulkheads and transom set up on building stocks.

Bottom skin going on. Plenty of clamps needed.

Bilge panel gong on. Keel deadwood and wood bilge keels fitted. This bilge keel is to protect the hull when aground, serving purely as a support to keep the hull skin clear of pebbles.

Forward bottom panel. Fitting this panel is the most difficult part of the build, due to the amount of twist in the panel. The twist is what forms the fine bow for good performance.

Hull epoxy-coated, primed and ready for paint.

Building the cockpit. Nicks work is very neat.

Interior, looking forward, built  before fitting the deck.

Interior, looking aft. Painting in progress.

Deck stringers glued into pre-cut slots

Painted and brightwork being done. Almost ready to get wet.

This view shows why these little boats are so quick. That fine bow works vvery well.

Launch day. The yellow boat below the bow is "Black Cat", the Didi 38 that I built.

Afloat and waiting for her rig to be set up.

Thank you, Nick, for the set of photos. She looks good and I am sure you will have many good times sailing her.
