The method of constructing a hull for ocean profiling or gliding vehicles which reduce the energy required to make vertical excursions. Composite materials are used in constructing the hull, specifically a fiber reinforced matrix, wherein the choice of the fiber material and orientation allows a balance of strength and elastic properties optimized for oceanic profilers and gliders thereby allowing operations with minimum energy expenditure.

I claim: 1. A method of optimizing the compressibility and pressure resistance of an ocean submersible vehicle to minimize the work required to change depth, said vehicle having a vertical ascent and descent cycle, comprising the steps of: forming a hollow pressure resistant hull constructed of a plurality of layers, each said layer comprising a plurality of strong and stiff linear fiber filaments embedded in a matrix; forming each said layer by winding said filaments in a helical pattern at a desired winding helix angle, said helically wound filaments having a different stiffness in an axial and a circumferential direction; adjusting the helix angle to obtain a division of load axial and orthogonal to the filaments to obtain a desired overall hull compressibility; and adding sequential layers. 2. The method as recited in claim 1, further comprising the step of: selecting said winding helix angle from the range of 55 to 75 degrees. 3. The method as recited in claim 2, further comprising the step of: selecting said fiber filaments from the group consisting of fiberglass, synthetic fibers, aramid yarns, and graphite. 4. The method as recited in claim 3, further comprising the step of: selecting said matrix from the group consisting of epoxy resin and other resins. 5. The method as recited in claim 4, further comprising the step of: comprising said fiber filaments embedded in a matrix as graphite filaments in an epoxy resin matrix.
