For an overseas bareboat charter, get the operator to confirm acceptance of your skipper evidence for the exact yacht and cruising area — ideally before you make a non-refundable commitment.
Evidence-of-competence requirements vary by country, and a charterer should ask the charter company what evidence will be acceptable for the specific area and vessel.
Often useful evidence of competence abroad, but not universally required or universally accepted.
