Welcome to the
PSUBS Personal Submersibles
PSUBS OSS (Open Source Submarine) Project


Last update: 30 Jan 2003 Scope: This page is dedicated to the OSS (Open Source Submarine) Project. OSS is a collaborative effort to design a submersible by the PSUBS group. Warning: Until actual hardware is built and proven to be safe this information is provided for intellectual discussion. PSUBS.ORG has not officially signed off on this design. Use at your own risk. Tempory OSS site



	The Open Source Submersible project was founded on the
	belief that concerted effort, pooled resources, and 
	freely available information would result in a better 
	Personal Submersible for all. Our goal is a Submersible
	within the reach of anyone, anywhere, with basic mechanical
	skills and determination.
