Global structural design of large sailing catamaran

Weight Estimation of Superyachts

Superyachts are expected to be perfect since the owner pays millions for them, and the worst that could happen is tilting the ship once it floats. The lightweight, including the center of gravity, is essential to know with a high degree of certainty to prevent this. However, the lightweight is already expected in an early design phase, when...

The Plug-in Hybrid Electric Superyacht: An operational data-driven design

This study aims to provide a proof of concept of a plug-in hybrid electric superyacht. In this way, the yachting industry can help reduce carbon emissions worldwide and potentially increase comfort levels. The concept takes advantage of the typical operating profile of a yacht. A statistical analysis is performed to discretise this and obtain...

A methanol impact tool for yachts: Assessing the impact of using methanol as an alternative fuel on the design, emissions and costs of yachts

Superyachts are large emitters of greenhouse gases, as well as other emissions such as NO_x, SO_x and PM. In order to meet the climate goals set by the IMO, to reduce GHG emissions by 50% in 2050, alternative fuels are being investigated. Methanol is an alternative fuels with great potential. Methanol can be produced...

The fuel cell powered superyacht: A research into the possibilities and consequences of using fuel cells to provide a superyacht in its energy demand

One of the most important reasons to investigating fuel cells is the increased level of regulation regarding emissions in the maritime sector, while fuel cells offer the opportunity to reduce these emissions. It was not clear what the impact of these systems would be on a yacht, the aim of this project is therefore to gain more insight into...

Steering towards Stiffness: A preliminary analysis method for local deformations in a yacht structure caused by wave-induced loads

The superyacht industry faces an increasing trend of larger dimensions, more open spaces, larger hull openings and more exotic shapes. This puts more effort on the structural design and especially for superyacht longitudinal stiffness is important, since the luxurious interior and delicate systems installed in a superyachts are not allowed to...

Design of an electric superyacht tender

The Dutch yacht builder Zeelander Yachts is working on a new brand Dutchcraft wherefore they want to follow the transition from combustion drive-trains to electric drive-trains by creating a 25-feet electric tender. The company never built a tender or electric tender before. Causing, that the company has no knowledge about electric drive-trains...

Composite Reinforcement of Conventional Aluminium Deck Design (Public Version)

Growing demand for larger accommodation rooms in superyachts result in larger deck spans at the cost of increased height of deck structures. (Conventional) aluminium poses a practical limit due to its relatively low stiffness, whereas composites are deemed overly expensive and unsafe in case of a fire. Composite stiffening of the primary...

A study on the stochastic modelling of load balances and the auxiliary power demand of superyachts in an early design phase

The design of a yacht for the year 2030

There is a highly elite club of individuals on this planet that has a very particular set of characteristics. To be part of this elite establishment one must have a minimal net worth equal to or exceeding 30 million US$ and be the owner of a yacht longer than 25 meters from bow to stern. The individuals who are part of this group have the...

Analysis of the impact of adjustments to the on board HVAC design by time domain simulations

The system for heating, ventilation and air conditioning (HVAC) on board of passenger related ships is one of the biggest energy consumer. The system is vital to the comfort of the crew, passengers and can improve reliability of equipment. Since fuel prices keep rising and green credentials of a ship become more important it is necessary to have...

The design of a luxury superyacht tender based on the 12,3m RIB hull of Xtenders

This project started with a visit to Xtenders where a tough model of a new concept came to my attention. This sketch looked different from at the time produced by Xtenders models and evoked some curiosity that emerged into the graduation thesis. Xtender is a Dutch brand that builds yacht tenders. The main advantage of the product has been...
