Frequently asked questions
Does CISR require ISM at the 24m-to-500GT tier?
CISR mandates ISM for vessels operating commercially. For privately registered vessels in this tier, ISM is voluntary but strongly encouraged by CISR for safety audit purposes.
How does CISR handle LY3 compliance for charter yachts?
CISR recognises the MCA Large Yacht Code (LY3) and Red Ensign equivalent codes. CISR surveyors audit to these standards or CISR's own Large Yacht Regulations.
What STCW requirements apply to Cayman-flagged yachts in this tier?
CISR requires all deck officers to hold appropriate STCW certificates. A 500GT vessel typically requires OOW 500GT, Master 3000GT, and valid GMDSS.
