About Vanclaes

We are the developer, brand name holder and producer of the Vanclaes stainless steel boat trailers and Vanclaes Marina Equipment. Vanclaes produces its own products in Alphen aan den Rijn and exclusively supplies them to consumers all over Europe via a carefully selected network of dealers and partners. Stian Duijvelaar, entrepreneur and product developer, is the head of the organisation. Vanclaes is unique because it uses stainless steel in its products and because of its unique, highly functional designs. In addition to industrial products for the marina market, Vanclaes also has the widest range of boat trailers on the European market. This makes the company an ideal partner for aquatic sports companies that specialise in the sale of both smaller boats and bigger yachts. Naturally, price is an important part of this industry, which is why Vanclaes offers a suitable high-quality solution for every budget. Vanclaes is quick, affordable and the undisputed leader when it comes to quality.

Our Goals
  1. Better Functionalities.

    Vanclaes makes the ins and outs with a boat trailer easier and more accessible for you. Our products take care of the hassle along the waterside and on the road for you and provide you with unprecedented ease and comfort during use.

  2. High quality and reliability.

    Vanclaes builds and delivers 100% premium products with a long service life with a very high reliability and is therefore exceptional within the international boat trailer market.

  3. Aesthetically and ergonomically well and beautifully made.

    If a product still costs a little more, it must at least look like this and feel like that when used. The practical, but often also the particularly beautiful design and the used materials, makes a Vanclaes product so characteristic and unique.

Our approach
At Vanclaes you will be totally unburdened.

In addition to deliver a new ordered boat trailer, Vanclaes can also take the entire process to configurate the right boat trailer for you. We adjust it completely under the boat and proceed a complete test at the slipway. This process of selecting and adjusting the right boat trailer product is often underestimated and unfortunately often goes wrong. Not at Vanclaes; we are happy to arrange a professional intake for you. In addition to charting your personal wishes regarding the use of a new trailer, your boat will be measured and weighed, so that nothing is left to chance. When the new Vanclaes trailer comes out of the factory, it is adjusted under your boat and thoroughly tested. No surprises afterwards and a 100% working solution are therefore guaranteed.
