Our program

We work with 3 quality levels, based on quality/price:

A - Line :  Our A-Line consists of the products from the well known high quality brands such as Wolf Safety, Bosch, Trelawny, Nitto Kohki and many others. This line is for the customers that only want the best, without compromise and are about to use the products very intensive.

B - Line : Our B-Line consists of the products from our own brand TETRA, but also other brands like Climax and  Jentan. For customer who want a good product but do not insist on top-brands and prices and who are about to use the product regularly but not intensively. 

C - Line : Our C-line consists of the products from our brand C-Line Marine. For customers who are very cost-consious.

Furthermore we have an extensive range of products to protect vessels against pirate attacks.

AP-Line : Especially for vessels that may encounter pirates we've developed our Anti-Piracy-line, with products to avoid pirate attacks or to protect vessel and crew from it.
