It's our birthday!

Sea Level 25 years.png

25th Anniversary


25 Years ago, putting our heads together, Bastiën Ligthart and Jeroen van der Knaap started Sea Level. Convinced that we could add a new vision to the world of superyachts: combining Yacht Design and Engineering under one roof …. ‘no good yacht design without good engineering and vice versa’.

In the second part of our existence, we developed new insights and became more focused on the technical designs and decided to end our activities in yacht design styling. Now, based in Amsterdam, serving a global clientele, our main field of operation is Naval Architecture specialising in Feature Integration.

Sea Level carries out feasibility studies and devises tailor-made solutions to best implement your custom feature into the ship's structure.

We are proud to, independently, serve the industry in the early stage of a project.

Monaco Yacht Show - 2023


You probably know that we are constantly looking for inspiration from outside our daily routine. So, as every year we will visit next week’s Monaco Yacht Show.

For this year’s visit we promised ourselves to fully focus on ‘tenders and toys’, looking into innovations in general all the way to new on/offboard handling possibilities.

And yes, we will also have a drink or two. Feel free to join!

High Performance Boats


You can never underestimate the importance of weight management when it comes to High Performance Boats. You could think: less weight is better, but this is not as true as it might sound.

As soon as a boat reaches high performance conditions, there is more in play than Archimedes’ law of upward forces. Both, ‘swaying’ and ‘surging’ come into the equation.

In planing condition, the upward force is provided by the lift force, just like with an airfoil. The downward force due to the ship's weight continues to have an adverse effect on the operation of the lift force, so you can say that the lighter the better.

However, a light, fast boat often doesn't drive well in waves, it's uncomfortable and it bounces around, and you would prefer a heavier boat with more weight in the back.

So you see that Sea Level is challenged with every High Performance Boat- project to come up with an 'ideal' configuration of hull shape, weight, weight distribution, propulsion and construction for the most occuring situations. We give the highest priority to safety and ergonomics for those on board.

A puzzle we like to crack with our 25 years of knowledge and experience by optimizing the process of precise weight measuring and distribution during the design, construction and delivery phase.
