Silura 25 Global · The fast ocean crosser

Built to be at sea.
Not at a dock.

A 25-metre trimaran for owners who cruise under their own power. It cruises at twenty knots, making distant places practical. When the wind is fair, a bow-launched kite shares the work.

Think of it as the Dashew FPB idea, brought up to date. Twenty knots on one diesel. A kite for the wind and a backup way home. Two cabins, by choice.

Built for a cruising couple who want range, self-reliance and the room to roam.

The vessel

A slender hull, built for passages.

The slender main hull slips through the water with very little resistance, allowing a twenty-knot cruise on a fraction of the fuel required by a conventional long-range cruiser. Two amas provide the stability that such a fine hull gives up.

To make that possible, the boat is kept exceptionally light at just eleven tonnes. Its structure uses E-glass and vinyl ester over a PVC foam core, with carbon reinforcement in the highest-load areas, and is designed to Lloyd's SSC standards.

Hull

Slender-body trimaran

A low-drag hull that holds twenty knots, where heavy displacement cruisers sit at ten.

Wind

Bow kite

An automated kite flies from the bow. In the right weather it's real propulsion, pulling the boat along off the wind and resting the engine. If the diesel ever stops, it brings you home.

Power

Single diesel

One diesel does the work. Cummins QSB6.7 HD as standard, with a Scania or Caterpillar upgrade for higher speed. About 41 litres an hour at the 20-knot cruise.

Drive

Controllable-pitch prop

The main propeller re-pitches to suit the engine, and feathers nearly edge-on when the kite is flying, so it drives hard under power and barely drags under sail.

Energy

44 m² walkable solar

Seven kilowatts of solar panels, feeding a 44 kWh house battery in the main hull.

Fuel

Single-fuel platform

Diesel everywhere, including the tender. One fuel and one system across the whole boat.

At rest

Designed for anchor

Built to live at anchor. The tender is your daily run ashore.

Range & capability

Range and capability over volume and cabin count.

2,000 nm

Range to spare

About 2,000 nautical miles at the 20-knot cruise. Ease back to 12 knots and the range extends beyond 5,000. Fuel is carried in three integral tanks in the centre hull, with two 800-litre ama tanks for the longest passages. No bladders.

Silent

Capable at both ends

One diesel and a controllable-pitch propeller on the open water, with a bow kite that takes over off the wind in a good breeze. Two optional 20 kW electric drives in the amas move the boat around an anchorage in silence. At anchor, solar and the 44 kWh battery carry the boat with the diesel shut down. No generator.

Two cabins, on purpose.

Forward and aft owner-sized cabins, each with a front-access queen berth. Two heads. The saloon, galley and inside helm sit on the main deck, while the engine room and steering gear are aft and below. A six-metre bow carries storage, the mooring gear and an electric thruster.

The boat is designed around two cabins, not compromised into them. It suits a cruising couple who occasionally carry guests, rather than a crowd they rarely do.

One tender, diesel like everything else.

The aft deck is sized for one substantial tender. A diesel jet tender is the natural fit. It shares fuel with the mothership, carries people like a dayboat, keeps its propulsion protected, and can be driven straight onto a beach. A five-metre RIB is the lower-cost alternative. The deck carries one tender properly, not two badly. Kayaks and paddleboards stow forward or on the cabin roof.

The commercial case

What it costs.

It sits against existing big expedition vessels, the top of the long-range monohull market. The case is simple. You get speed and range, and you don't pay for volume you won't use. The kite and the controllable-pitch propeller are standard. The Pacifica 17 tender is extra.

The buyer

The Silura 25 Global is designed around a simple idea: a cruising couple who want to go further, faster and more independently than a conventional yacht allows. Everything else follows from that.
