We strongly recommend all guests to purchase comprehensive dive accident insurance and trip cancellation insurance before departure. Dive accident insurance covers medical treatment, hyperbaric chamber costs, and emergency evacuation in the event of a diving incident. Trip cancellation insurance protects your financial investment — not only if you need to cancel or cut short your trip due to personal illness, injury, or other unforeseen circumstances, but also if the trip is postponed or cancelled by the operator due to severe weather, technical issues, or other operational reasons. In the unlikely event of operator insolvency, cancellation insurance can also help recover your payments. Please ensure your policies are valid for the entire duration of your trip and cover the planned activities.
A valid dive medical certificate is required for all guests on this vessel. The medical form must be signed by a licensed physician and confirm fitness for diving. Please upload your medical certificate when managing your booking.
BCD: 22 USD per day · Dive Computer: 11 USD per day
