JP 45 Hard Top

Our last project made in cooperation with JP Marine – a combination of a highly effective stepped hull (Adam Younger design) and high performance drive systems – France Helices surface drive.

JP45 Open


The boat has been designed with the most modern design method using final element methods (FEM), computational fluid dynamics method (CFD) as well as BV rules.



The cutting-edge technology and two step 22 deg deep V hull, wave piercing bow guarantee performance and comfortable ride. To fulfil the requirements, the highly efficient hull has to be incorporated with as low as possible weight of structure (epoxy infusion and Kevlar, carbon reinforcements), equipment and suitable drive system where reliability is the most important factor. To meet expectations, FPT 570 hp diesel engines – the best in this class – and France Helices surface drive have been chosen as a reference base. The main goal during working on the concept of this boat was to join performance, high finishes and social site of the boating .


The deck is designed to make the most of available space enhancing the comfort and layout of the area. For this purpose and to increase the safety factor (additional buoyancy and hull protection) D shape variable geometry foam (with pressured core) tube has been added. This allow on wider internal beam and much more space than other similar size boats.


Style, line and colours – the whole deck and cabin design was made with focusing on modern trends, details and ergonomics. However, everything is a matter of individual taste and each boat can have a different climate and layout.

To give you a better sense of sea adventure, the side windows are movable and the sunroof too. The first row of seats has a shock absorption function with adjustable height and weight depending suppression. All finishes are made from high class marine leather. The modern style is underlined by a unique glass bridge with 15” plotters and a digital switching option showing a clear and intuitive helm station.
