Was HMS Ocean built on an Invincible hull?

Ocean is better understood as a design cousin derived from related studies, people, and requirements than as a copied Invincible hull.

Question

Was HMS Ocean essentially an Invincible hull reused for an amphibious helicopter carrier?

Short answer

No. Ocean shared design ancestry and visual traits with Invincible but used an evolved, commercialized hull tailored to amphibious work.

Notes

HMS Ocean was not built on an Invincible hull. The ships share a family resemblance because related designers worked from overlapping studies and aviation-ship requirements. Ocean's hull form was evolved for different hydrodynamic and amphibious needs, including arrangements for launching craft. It was built to commercial standards with naval-style subdivision rather than as a lightly modified Invincible. The disagreement with D. K. Brown concerns how strongly to describe that relationship, rather than whether shared design ancestry exists.
