Aircraft and Yacht Governance for Family Offices
Aircraft and yachts combine the largest non-investment costs in many family offices with the lightest governance.
Key takeaways
- —Annual operating cost is typically 8-12% of acquisition value for aircraft, 10-15% for yachts.
- —Charter or fractional often beats ownership below threshold-utilisation hours.
- —Registration jurisdiction has tax, regulatory, and operational consequences.
- —Usage policy across family members prevents friction.
Aircraft and yacht ownership are among the largest discretionary costs many UHNW families carry, and they are often governed less rigorously than smaller items in the office's investment portfolio. The economics are unusual: acquisition is a one-time cost, but operating costs run 8-12% of acquisition value annually for aircraft and 10-15% for yachts, exclusive of depreciation. Below threshold utilisation, charter or fractional almost always wins.
Working governance for these assets covers four recurring decisions: ownership versus charter, registration jurisdiction (which affects tax, crew rules, and operational restrictions), crew structure and oversight, and usage policy across family members. Documenting each decision and reviewing them annually keeps the asset from drifting into either disuse (sub-optimal economics) or contested usage (family friction). For multi-generational families, succession arrangements for these assets deserve their own conversation — typically separate from the rest of the estate plan.
