La Cattiva Dive Platform

Commissioned to design and develop a replacement stern entry system and dive platform, this was one of PE Marine Designz early bespoke design and build projects.

Existing Stern Entry

The existing stern-entry system was comprised of a number of panels and support wires that were manually assembled – often taking up to 30 minutes to deploy and the same again to stow.

The main components, including the wings used for the dive-platform, consumed valuable stowage space on board.

The Design Solution

The solution we developed was this completely automated hydraulic platform.

Featuring some of the largest multi-pivot hinges we had built at that time, and a custom-designed hydraulic power system, the new platform now deploys in under 5 minutes.

An important feature of the final design solution was way the two “wings” hydraulically fold over the central wing, which in turn folds up over the steps.

The complete assembly then retracts into the hull forming a clean transom – and the back face of the central wing locks into place forming an integral part of the stern deck.
