Jet Shark - Fast Fun! Or even more?

Jet Shark - Fast Fun! Or even more?

Gepostet von | 16 Feb 2023 | , , , | 0

The two New Zealanders Rob Innes and Dan Piazza started out 25 years ago as Innespace, later Innespace Productions in Northern California, with small, fast and also limited submersible watercraft of various propulsion types. For almost 15 years, they have been building fish-shaped high-performance fun boats by hand - expensive, but unique and spectacular. Their latest coup is the "Jet Shark", a further development of the "Seabreacher", which is delivered to solvent customers in exclusive small series as a 5 metre long shark, dolphin or orca, individually airspray-painted with a 1.5 litre supercharged four-stroke engine (230 hp) and water jet propulsion. Video of the "Seabreacher" "Jet Shark" is larger, has a navalised 500 hp...

Special rudder for the F126 frigate

Special rudder for the F126 frigate

Damen Naval, the main contractor for the four F126 frigates, has commissioned Damen Marine Components (DMC) to develop and produce the required rudder pairs for the combat vessels. They are intended to improve the hydrodynamic properties of the ships and withstand extreme impacts. According to Damen, the DMC full spade rudders of the Atlantic type have been calculated according to the special hull shape and operational profile of these frigates. With their slim profile, the rudders reduce flow resistance and improve the F126's ability to maintain its course at high speeds, Damen continues. Good manoeuvrability at low speeds in harbours or during special missions of these naval vessels is maintained....

Plectrum: Floating at sea at 75 knots? A dream?

Plectrum: Floating at sea at 75 knots? A dream?

Under the name "Plectrum", the designers at the Italian Lazzarini Design Studio in Rome have presented the concept for a spectacular hydrofoil superyacht with hydrogen propulsion, which will glide across the water at around 75 knots (140 km/h) in the utmost luxury. However, they have also set a budget of 80 million euros for it - it could be more expensive if they don't get round to it soon! But Pierpaolo Lazzarini and his team don't think about saving money when designing their objects: With a length of around 75 metres, the "Plectrum" - once built - would actually be the largest hydrofoil in the world....

Gepostet von | 1 Feb 2023 | , , , | 0

The first Hull Vane for the Royal Dutch Navy was delivered in Den Helder at the beginning of June 2022. This is a baffle plate to be fitted under the stern that makes ships faster and quieter, i.e. more efficient, while also improving their sea behaviour. This guide plate will be installed on the transom of the "HNLMS Groningen", one of the four 108-metre-long and, at 3,800 tonnes, frigate-sized ocean patrol vessels (OPV) of the "Holland" class, at the beginning of 2023. Development In 2015, Dutch hydrodynamics specialist Hull Vane BV, as the patent holder, calculated in a study that the guide plate could reduce the annual fuel costs for a patrol vessel by around 13 %. The Defence...
