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.

Western Europe Section “Large Yacht Stability” by Andy King, Houlder Ltd. 7th January 2025 WES held its first meeting of the new year on Tuesday, 7th January. As usual, the meeting was held in hybrid format, with a total attendance of 56 attendees appreciating an excellent presentation from Andy King. Large motor yachts occupy an unusual space in the Naval Architecture world. Their owners demand a mix of operability, opulence and originality and hence their designs continually push the boundaries and require fresh thinking. The stability of these vessels is particularly interesting because of the goal of large open arrangements, novel design features and openings close to the waterline. 2024 saw the introduction of the new Red Ensign Group Yacht Code and, with it, the implementation of some new stability requirements. The presentation focused on these changes, and indicated how designers can ensure a compliant design and also how Masters can understand the stability booklet.

VESSEL REVIEW: Norwegian boatbuilder Salthammer Båtbyggeri (SHB) recently delivered a new custom workboat to Norwegian marine services provider Hansen Maskin and Transport. 'HMT Thor' was built to a design developed by Norwegian naval architecture firm Tomra Engineering in close cooperation with the owner. The boat has a length of 26.1 metres (85.6 feet), a beam of 15 metres (49 feet), and an open forward deck that can accommodate various payloads. SHB said the vessel can be operated in support of customers in the aquaculture and marine construction industries. Lasse Stokkeland, General Manager at SHB, said the vessel was developed continuously, with redesign work and integration of new capability at various stages, and that all components used in the construction were sourced locally.

Today marks a special day in a project that we are following closely. With the mounting of the keel the sailing yacht zero is one big step closer to sailing the oceans - and eventually operating without using fossil fuels. We’ve been following the construction of Zero very closely for a while, for all its interesting and innovative technology on board. Fundamental for the design and build of this project is the close collaboration between the industry leaders VRIPACK DESIGN, Vitters Shipyard and Dykstra Naval Architects, and the support of many industry experts. We are so curious to see its next steps and will showcase more interesting technology used in the project here. #RenewableEnergy #EnergyEfficiency #Innovation #MarineEngineering #TechInnovation #ShipTechnology

As we look into what 2025 has to offer, we are pleased to share this short teaser video on the progress of our Innovate UK CMDC Solent Tri Foiler Project. We are looking forward to moving into our testing phase in the coming months. Our team continue to develop next generation vessel designs. We take care to balance engineering innovation and trusted naval architecture. We are designing, building and testing to learn and be in a position to give best guidance to shipowners, shipbuilders and educators on the rights and wrongs of possible maritime innovations. Nice to see Lucas Barrozo Brun, Chris O'Neill and Tom Partington practicing what they preach wing foiling on a cold November morning...

🚢 Optimizing Ship Design: Wave Resistance and Efficiency 🌊 In naval architecture, understanding the balance of wave resistance (C_W), residual resistance (C_R), and frictional resistance (C_F) is key to improving ship performance. These factors, along with concepts like the Froude number (Fn)and slenderness coefficient, help engineers design vessels that move more efficiently through water. One fascinating insight is how wave interference between the bow and stern can either boost or reduce resistance, depending on their phase. This plays a crucial role in fuel efficiency and sustainability. By mastering these principles, we’re able to craft ships that are not only faster but also more energy-efficient, paving the way for a more sustainable future in maritime transport. 🌍 #NavalArchitecture #ShipDesign #WaveResistance #Sustainability #Efficiency
