Wim’s Story – the Design of Dione IV

While sailing on my previous boat, the ‘Dione III’, the ideas about my next boat arose. Especially in strong winds and bad weather, my Shipman 28 reached her limits. I wanted a bigger, stronger, and heavier boat. My preference for a ketch rig had always been there. I like the sight of multiple sails on multiple masts instead of the simple triangle shape on most yachts.

So, I started thinking about a sturdy ketch.

August 2002

While I was in Lisbon on business, on a day off, I visited Belem Marina. There, I saw a beautiful boat named Pandora. I had been thinking about a new boat for a while, and it looked like all my ideas about style and layout were in this boat: clipper bow, deck salon, ketch rigged, and heart-shaped stern. Though with her 48 feet, she was a bit bigger than the boat I had in mind.

Back home, I contacted Dick Koopmans, the famous Dutch naval architect and yacht designer. His father, Dick Senior, sailed the oceans with his wife Elly in 5 of his own designs and they wrote 4 books about that.

Dick Sr. had designed a ketch with the beautiful lines I liked so much on the ‘Pandora’ and Dick Jr. showed it to me. It is their design ‘156’.

Here’s the original 156 under full sail in the 1970’s, underway with main sail, mizzen sail, mizzen stay sail, jib and spinnaker! The yankee sail is on deck.

A beautiful ship, for sure, but I wanted a deck salon…

Dick Jr. said, “I can design a deck salon on this hull”… and he sent this picture.

That started to look like something!

There was one problem however, the hull of the 156 design has a flush deck and below this deck, there was not enough standing height for me.

On a sailing trip with my former boat, I saw another Koopmans design, the ‘330’. That one has an elevated salon roof (with the 4 little portlights) and that inspired me. Like this, there’s enough standing height.

Back home, I call Dick with this idea.

Dick says, “I can easily add an elevated salon roof”! But he’d need to check with his father, because they had never before designed a boat together… each had previously created their own designs, so doing a joint design was something new and very special. Dick Sr. agreed that this would be a good design and then they sent me this drawing.

I was in love! This is it!

In the first months of 2003, Dick transfers the paper drawings of the hull (made in the 70’s by his dad) into a digital form. In that way, he can supply all shapes and sheet metal layouts in a 1:1 plot for the construction of the hull.

Every week I get more detailed drawings.

Deck plan.

After some visits to several yards, I chose one to build the hull and we sign a contract. It says:

“A spacious, strong, safe, low-maintenance, comfortable, stable and well maneuverable yacht. Suitable for all waters of the world.”

That sounds excellent!

In the meantime, I’m making drawings of the interior design on my computer. Although Koopmans had a proposed interior layout, I wanted to incorporate my own ideas into the design.

The first pieces of the steel frames are bent.

And spot-welded together on a 1:1 plot of the drawings of the frames.

The keel and the first frames are in place, and that is a time for a small keel-laying celebration with some family and friends.

The first screw of a stainless steel keel plate is attached by my daughter Dione.

Second screw by my daughter Yara.

The last screws by myself.

Many happy miles, Dione IV!
