Frequently asked questions
Does IOMSR have experience registering vessels over 3000GT?
Yes - IOMSR has registered several of the world's largest private superyachts and expedition yachts. The registry has dedicated technical staff for large vessel survey coordination and ISM/MLC compliance oversight.
What ROs does IOMSR recognise for class surveys on vessels over 3000GT?
IOMSR authorises Lloyd's Register, Bureau Veritas, DNV, RINA, American Bureau of Shipping, and ClassNK as Recognised Organisations for delegation of statutory survey functions.
How does IOM corporate law benefit owners of IOMSR-flagged gigayachts?
IOM-incorporated yacht-owning entities benefit from 0% corporate income tax on passive income (including yacht charter income held offshore), efficient trust structuring, and strong asset protection - making IOMSR registration and IOM ownership structure a common pairing for UHNW owners.
