guide to make boat

Bruce Mierke is building a Didi 29 Retro in Murphy, North Carolina. Bruce is a professional boatbuilder, building her for himself and progressing nicely. He has now completed the hull and it will be turned over in a few weeks.

This design is based on the Didi 26, modified to create a more classic image. Carrying a choice of rigs, the squaretop Marconi rig below and two gaff rigs further down the page. It is a radius chine plywood design, round bilge from plywood and can be built from plans or a CNC kit. Although Bruce is a professional builder, I developed this construction method primarily for amateurs and they have built many boats to this range of designs.

Here are the latest photos from Bruce, showing the beautiful standard of finish that he has achieved.

Beautiful hull finish.

I designed the Didi 29 Retro for Mike Kopman, a professional charter skipper who lives in my hometown of Hout Bay, South Africa. Mike's concept was to adapt the Didi 26 cruiser/racer design to a more traditional concept, with counter stern, bulwarks, boxy trunk cabin and a big gaff rig, for participation in the Caribbean classic racing circuit. Mike received the first CNC kit to this design, supplied by CKD Boats in South Africa. The second kit went to Bruce Mierke of Murphy, North Carolina, which he ordered from our list of plywood kits.

Mike Kopman has been building his workshop ahead of the boatbuilding project, so that hasn't started yet. Bruce Mierke started his boat a few months ago and is moving along very well. These photos are of Bruce's build. He began with some smaller items ahead of starting the hull, so I am showing those first.

In a November post I wrote about the Didi Sport 15 that is being built in Port Elizabeth, South Africa, by Jim Foot. Jim has continued to build at a good pace and his boat is moving into the final stages of construction.

Jim has provided a steady stream of photos that document his project through all of its stages. He appears to be doing a very capable build and his boat should be sailing within months.

Jim bought a plywood kit from CKD Boats in Cape Town. It was cut by CNC router using cutting files that we prepared and supplied. Similar kits can also be cut by our other kit suppliers in other countries.

Beautiful standard of hull finish shows off the hull shape.

Thanks Jim for your photos and for your enthusiasm. I look forward to the launch and sailing photos of your new boat.

Tiernan Roe is a professional boatbuilder in County Cork, Ireland. His company, Roeboats, specialises in building quality wooden boats. Mostly of classic styling, they build for sail, power or rowing. Roeboats recently launched a Cape Henry 21 that they built for a customer from France.Tiernan sent me these photos, which show some interesting details brought into one of our most popular small cruisers.

Launched in a pretty setting.

The mainsail has still to be fully set up in these photos.

Compact sink & cooker unit, neatly executed.

Other side of the galley. Nice detailing.

Looking aft from the double forward berth.

You can follow the construction of this boat on the Roeboats news blog, from start through to launch.

After launch, Tiernan Roe sent me these comments. "She sails very nicely and I found her easy to single hand from the get go. The interior is pretty snazzy with frame and panel oak fronted drawers and a gas stove with tank fed sink.  Also the centreboard was a lot easier to operate than I thought. It's an awkward shape out of the boat to try and move alone."

Until now I have only shown the DS15 prototype, being built in Virginia Beach, USA, by Aussie Hunter Gall. Hunter's project is currently stalled due to circumstances but one of the the other builds is steaming ahead apace. This one is being built by Jim Foot in Port Elizabeth, South Africa. This weekend Jim applied the last coat of epoxy to the outside of his hull and is preparing to paint it.

This series of photos shows the basics of Jim's project up to this stage. This is a radius chine plywood design, with hard chine along the topsides. It is the same family of designs as the Didi Mini Mk3 and Didi 950.

Frames set up on building stocks, with stringers going on.

Stringers all done and bottom panels fitted.

Same stage, showing stringers running into forefoot.

Side panels fitted and first layer of radius progressing.

Stitch-&-glue detail of topside chine.

Second layer of radius going over first layer.

Completed radius chine, running smoothly into flat panels.

Glass taping centreline seam. Jigsaw joints of bottom panel can be seen.

Epoxy coatings started.

Nice finish starting to show.

Clean stern and nice finish.

Final coat of epoxy, ready for sanding and painting.

I will show more of Jim Foot's project as it progresses toward launch date. I tend to show the projects for which I receive the best photos, so please send me your best pics if you want to see your project on this blog or the Dudley Dix Yacht Design main website.

Steve Watson is building a Didi 23 in Hood River, Oregon. Last week he and a few friends pulled the hull out of his garage, rolled it over in the driveway then returned it to the garage for work to start on the interior. These photos show the process that they used.

Pulled out of the garage.

Half-way over. A hull is intimidating in this position and must be controlled. Gravity can quickly become the boss.

Safely over and resting on mattresses. Builder Steve Watson at right.

Stern view. Steve has added a scoop stern to the transom.

Going back into the garage for work to continue.

A boat-under-construction takes on a whole new character when it is turned right-way up. This is the first time that the builder gets to see it right-way-up and the final shape of his creation.

Hull-turning is a memorable milestone in a big boatbuilding project. This is always a good time to have a party, to take your rewards and gather your thoughts, resources and energy for the next stage of the project.

The way that Steve and friends turned this hull worked for them. The bigger the boat, the more complex the turning process becomes and the more care that must be taken with preparations and equipment to keep this heavy structure under control. Carelessness with this phase of the project can injure or kill people and also damage the carefully-built boat.
