Knock on wood

Turkish shipyard Soyaslan showcases its talents with one of the world’s largest wooden catamarans.

03 August 2022


Boutique boat builder Soyaslan has launched what is believed to be the world’s longest cold-moulded catamaran.

The striking CAT63 project measures 19.37 metres overall and was designed and built by the specialist Turkish builder, with styling from Tumer Design Studio.

Regardless of the material, the ultra-modern lines of the boat are set to rivet attention in any port or anchorage.

The shearline swoops from low sterns up toward the heavily flared bows of the boat, which are raked aft. The white coachroof seems to hover above a pool of black glazing, with a streamlined hard-top shading the flybridge.

That such a complex design should have been built using the cold-moulding construction process is a testament to the skills of the Soyaslan’s workers and the ambitions of its designers.

“We have good experience in engineering and manufacturing with this method,” said Founder of the company, Can Soyaslan.


“We have engineered and built cold-moulded yachts which are already 30-plus years old. To date, we have produced more than 100 boats and yachts.”

Cold moulding is the method of building up a shape by forming sheets or planks of wood over a plug or frame.

The individual wooden elements are glued together with high-performance epoxy and later sheathed in epoxy for protection and longevity.

“In the final look, users cannot tell the difference between a cold-moulded yacht and a GRP or metal one,” continued Soyaslan.

“In practice, the durability and longevity of the hull is without comparison. Wooden yachts can last well over a hundred years, while the vibration, sound and heat insulation are much better.”

Weight for weight, there is little difference between cold-moulding and GRP. But of course, wood is a sustainable material and there’s also the sense of true craftsmanship that only comes from using wood.

“It’s not easy to explain, but you can notice and feel the difference of a wooden hull when you get onboard. It feels warmer and more honest,” said Soyaslan.

But the construction method is just one of the unique features of CAT63. Soyaslan is renowned for its commitment to technology and the evidence is everywhere aboard.

The 63-foot catamaran is powered by twin Yanmar 110 hp engines, hooked up to big ZF saildrives, for an 8.5-knot cruising speed and over 10 knots full throttle. There are 60 kWh of lithium batteries aboard and no fewer than eight 430 W solar panels.

“With the current setup she can spend the night at anchor without generators, even with the air conditioning running. And with eight solar panels, we have minimised the generator usage,” explained Soyaslan.

Accommodation runs to two large double cabins and two twins for eight guests, plus a further three berths for crew.

Tumer Design has created an interior that feels modern and minimal, with a neutral palette of darker colours blended with colourful blue and orange patterned fabrics.

Atmospheric lighting allows you to switch from a calm, relaxed vibe into evening entertainment mode, with social spaces inside and out. Naturally, there’s a large electrically controlled bathing platform aft which carries the 3.5-metre tender.

Sailing should bring plenty of excitement, with a generous sailplan that includes a 100-square-metre mainsail, a 58-square-metre jib and a giant 145-square-metre Code Zero for reaching.

Little wonder the boat achieved better than 10 knots during sea trials. A stylish bowsprit offers plenty of downwind sailing options, while windward performance gets a boost from the swinging centreboards in each hull.

Twin wheels are located at the forward end of the flybridge and there’s a full navigation station in the saloon below.

“Our whole team is very proud of this sleek, powerful catamaran,” stated Soyaslan.

“The yacht will bring her owner safely and comfortably across oceans and provide an excellent cruising platform.

“It’s further proof that our company excels at delivering complex and inspiring designs for owners who do not accept the status quo.”
