FEATURE: Norwegian naval architecture firm YSA Design has unveiled a concept for a new type of sail-powered catamaran cruise ship that offers the flexibility to access waters where larger vessels will have difficulty operating. YSA Design said the design includes a host of features to attract premium-end cruise guests while combining the sustainability of sails and a four-metre draught in a 104.5-metre-long ship with access to shallow waters. Dual hulls counteract listing under the sail to maintain stability and comfort for up to 200 guests on board. Four 50-metre-high foldable sails will be mounted on six-metre-high bases on deck to capture the wind. Engines running on green bio-methanol will sustain hotel operations and – if wind was insufficient – the main propulsion, although the ship will also be enabled with a hybrid drive to incorporate silent running on battery power.

Understanding Ship Trim: A Key Concept in Naval Architecture Maintaining the correct balance of a ship is critical for stability and efficiency. The way weight is distributed onboard impacts the vessel's orientation in the water. Here are three common trim scenarios: 1. Even Keel: The ship is perfectly balanced, with the gravitational and buoyancy forces in equilibrium, keeping the ship level. 2. Trim by Stern: When additional weight is placed at the stern (back) of the ship, it causes the stern to sink, tilting the ship downward at the rear. 3. Trim by Head: When more weight is added at the bow (front), the ship tilts forward, causing the bow to sink lower in the water. Check out the illustration below to better understand how these forces work to affect a ship's stability!

VESSEL REVIEW: A new research vessel was recently handed over to the National Institute of Water and Atmospheric Research of New Zealand (NIWA). 'Kaharoa II' was built by Armon Shipyard of Spain to a design by Norwegian naval architecture firm Skipsteknisk to replace an older, slightly smaller similarly named vessel that has been in service for more than 40 years. The onboard facilities include wet and dry laboratories of more than 12 square metres (130 square feet) each, a conference room, and five cabins. The aft deck has a total area of 85 square metres (910 square feet) for the transport of additional equipment. Full article link in comments.

A week on from a great couple of days at The Superyacht Forum for Houlder Limited. Pleasure meeting new people and re-connecting with others. Particularly enjoyed the directions on sustainability, meeting the Water Revolution Foundation's YETI, the open discussion on yacht incidents and the great quick-fire format of the VRIPACK DESIGN Night Out. One slide stood out from all the information presented - showing that yachts spend just 10% of their time cruising. This almost exactly mirrored interesting incident data presented by CHIRP. It left me thinking... so much of a yacht's stability compliance is focussed on when it is cruising in "seagoing loading conditions". The conventional Departure and Arrival conditions. So do we need a re-focus on stability compliance when the yacht is not cruising? When it is spending 90% of it's time going nowhere? Certainly something worth thinking about. - Please reach out if you would like an independent appraisal of your yacht's stability booklet. - Please contact Houlder Limited for Naval Architecture and Marine Engineering consultancy services. - Credit to the Water Revolution Foundation for the slide below.

Naval architecture, the art and science of designing boats and ships. It involves knowledge of mechanics, hydrostatics, hydrodynamics, steady and unsteady body motion, strength of materials, and design of structures.

Designing the perfect tailor-made vessel is a challenge that Vard Marine Inc rises to every day with the help of NAPA’s design tools. Denley Rumbolt, P.Eng. Project Naval Architect, and lead NAPA user at Vard Marine explains how the team at Vard Marine takes customization to new heights -making every detail unique to the customers’ needs and preferences. While such levels of customization are no easy feat and can entail numerous iterations of the proposed design, our NAPA design solutions help give naval engineers more flexibility to manage the multiple iterations that are inevitable with novel designs, as well as the ability to validate the feasibility of concepts earlier in the process. Pretty cool, right? Read more about how NAPA helped Vard transform and digitalize its workflows to enable innovation at speed and scale. https://lnkd.in/g79_prPD #Maritime #ShipsandShipping #ShipDesign

The ocean has always been my teacher. As a young surfer, I learned to read its moods, feel its rhythms, and respect its power. But as I grew, so did my curiosity. What was it about waves, their formation, their energy, that captivated me so completely? That same curiosity is what led me to become a naval architect. Not to design ships, but to design solutions that honour the sea, protect it, and ensure we can co-exist sustainably. This is my story of how understanding the science behind the waves helped shape my journey to preserve the oceans I love. https://lnkd.in/e4EKmCxG

Somec Navale, part of #Horizons, has been awarded orders worth €65.5 million, including €16mn under option, for the construction of seven #newbuild cruise liners in collaboration with leading shipyards across #Finland, #Germany, and #Italy. In 4thQ/24, order intake exceeded ~€148mn in challenging and innovative projects in both naval architectures and curtain walls.   🛳️ What’s on deck? - Turnkey #balcony systems: cabin windows, doors, and vertical sliding components. - #Glazing for upper deck bows with innovative sunshades. - High-performance sliding doors and windows, designed for mechanical resistance, thermal insulation, and #sustainability.   📅 Deliveries are scheduled between June 2027 and mid-2030, with the financials impacting the 2ndH/2025 through 1stH/2029.   #worldleaderinmarineglazing #NavalEngineering #qualitàcostruttivaitaliana #SomecNavale #CruiseIndustry

VESSEL REVIEW: French cargo transport company Grain de Sail has expanded its fleet with the recent acquisition of a new vessel delivered by local shipyard Piriou. 'Grain de Sail II' was built at Piriou’s Vietnam facilities to a design by French naval architecture firm L20Naval. It is notable for its large sails, which make it the second vessel in the Grain de Sail fleet to have such features. The rigging is developed using proven technologies and industry practices in construction and maintenance, resulting in a sail-to-displacement ratio of 2.5 square metres (27 square feet) of sail per tonne. This ratio means the ship can reach speeds of up to 12 knots while making it possible to reduce carbon emissions by more than 90 per cent compared to a conventional ship on an equivalent journey. The main goal of navigating without engine assistance is to reduce environmental impact as well as engine noise, which would otherwise have a direct impact on surrounding marine life. A series of trials undertaken in different weather conditions and with different sail plan configurations confirmed that the ship’s hull, coupled with its schooner rigging, is more efficient than expected in speed with optimum balance under sail. The vessel itself is also structurally designed to withstand cyclones, ensuring safe use in the Atlantic in all seasons. Full article link in comments.
