Designing Composite Hatches: Solving Leaks, Weight & Serviceability

Описание: After 32 years, Paikea's original deck hatches were leaking, heavy, and difficult to service. Rather than opting for an off-the-shelf solution with its own compromises, we engineered a complete composite hatch system from scratch.

This video details the design philosophy and engineering behind our new hatches, covering:
The analysis of why commercial hatches failed to meet our specific needs for offshore sailing.
The critical design elements: flush mounting, integrated gutters, and a structural rim that reinforces the deck.
The development of custom 3D-printed nylon-carbon friction hinges for ultimate serviceability.
How a circular lens reduces weight and heat gain while maintaining strength.
The final result: a hatch system that is half the weight of the original, fully flush, and designed to meet ISO/ABS standards.
This is applied marine engineering for a real-world refit problem.
