A Composite Case, made with a foam core sandwich structure.

Due to the closed cell foam used in the construction, even if the case is punctured, it will not sink, even when its entire volume is water.

A great product for keeping your valuables safe onboard, or as an emegency grab case should the unthinkable happen.


Available in all of our standard sizes. There is slight loss of internal dimension due to the thickness of the laminate in these products but, it is a minimal loss for a massive gain!


We are aiming to have completed testing on this range by the Autumn of 2021 and launch to market thereafter.


Keep up with the progress on this site and on social media.
