About the Jet Thruster Team

Holland Marine Parts in Dordrecht, the Netherlands, manufactures the Jet Thruster. Owner-manager Henry Kroeze and Sales Director Pieter Cats are the familiar faces of the company. 


The Jet Thruster is a unique system that uses water pressure to easily manoeuvre pleasure boats from 25-60 ft. Since 2010 It finds its way from Dordrecht, The Netherlands, to customers all over the world.


The current Jet Thruster has a comparatively short history, contrary to Henry Kroeze’s, who has over forty years’ experience in metalworking and plastic processing industry.


In addition Henry Kroeze has vast experience as an entrepreneur in the maritime sector. In this capacity he supplies, among other things, motor components to shipbuilders at home and abroad. 


One of Kroeze’s traits is that he never ever stops at half measures. He strives for perfection, and this was evident in the development of the Jet Thruster.


In 2020 Holland Marine Parts celebrated it's 10-Years anniversary

Composite Parts

The next level 
in marine Technology

                     
   Benefits of Composite material

"We keep developing better products"

All composite parts from Holland Marine Parts are moulded from a glass-reinforced nylon composite, offering light weight and high strength.
Glass fibres within the Nylon composite provide stiffness, toughness and dimensional stability to the material, exceeding ABYC and ISO9093 requirements for strength and durability.
Nylon composite materials eliminate the need for electrical bonding systems, preventing the problems associated with metallic thru-hull parts and ball-valves
Chemical Resistance of Nylon Composite prevents deterioration by diesel or other petroleum based products, and means or nozzles can be painted with anti-fouling paint
UV-Resistance of the Nylon-Glass substrates prevents discoloring and deterioration
Nylon Composite has a large operating temperature range, and fire resistance equivalent to the FRP hulls of most recreational watercraft
Composite materials reduce risk of bellow the waterline damage associated with metallic thru hulls caused by lightning strikes
Our Slide and Lock Technology makes for easy installation, and insures our nozzles remain fixed in place with high level of security

Testing and certification

Before bringing our products to the market, we have performed many tests and studies. 

Composites have proven to be a reliable material. We have tested the strength of each composite part, which has been surveyed and certified by a Notified Body. 

The composite Thru-hull parts have been tested and withstand a static load far greater than the Directives indicate. 

Contact us in case you are looking for more information about the Composite parts.

Fluid dynamics

Pumping water is more than interesting. With Fluid Dynamics software we have developed all components in the Jet Thruster system. Each pump is 100% tested after it's being assambled.
