What should be assessed before committing to a slipway launch?
Short answer
Slip condition, tide, wind, current, obstructions, traffic, and recovery window
The release decision joins the actual slip, people, environmental forces, local constraints and future recovery state; another rig or a single depth observation cannot establish suitability. Revise launch-site-assessment.
