    Lionfish IV requires a crew of 2, consisting of Master Class 5 (Skipper) Marine Engine Driver 2 (Engineer) and we generally also have a Deckhand (Usually a Dive master or Cook).

    • Once monies are paid, cancellation and amendment fees may apply. 
    • This is determined by when the cancellation or amendment occurs. Refunds can be made if we are able to rebook the time period so the more notice the better.
    • Please make your guests aware that drinking pre/post cruise is not permitted on the jetty.  No opened bottles on jetty.  There will be a bin for your guests to dispose of their opened drinks on disembarking.
    • The vessel will terminate the cruise at any time if responsible serving and consumption of alcohol is not adhered to.  This includes under aged drinking, suspicion of abuse of illicit/non -prescription medication or offensive behavior.  Whether the offending people or the whole group be taken to the nearest jetty and charter terminated is up to the skipper.
    • With BYO alcohol please refrain from bringing along too much alcohol. If the skipper feels the amount is excessive he will discuss with you and store the excess which will be returned to you post cruise. At the same time it is embarrassing if you run out.
    • Any intended passenger who in the opinion of the crew shows any signs of intoxication either from alcohol or any other substance abuse prior to the commencement of a charter will be refused access to board the vessel. Any subsequent attempts of that person or others to argue with the crew may result in the termination of the entire charter.
    • Any person/s deemed to be intoxicated by the skipper or crew will be identified to the charter organizer. It will be the responsibility of the organizer to ensure that person does not consume any more alcohol for the duration of the charter. If this is not complied with the person/s may be removed from the vessel at the nearest jetty. The vessel will only return to the charter once the skipper is satisfied that that person/s is safe and in the care of a responsible person. Lost charter time will not be made up and the charter will conclude at the scheduled time. If the situation is serious enough the entire charter may be terminated without compensation. Costs associated with removal from the vessel i.e. taxis, public transport are the responsibility of the person/s being removed.
    • Unless terminating at a public jetty, all leftover beverages must be removed from vessel at end of charter. No opened beverages are allowed to be removed from the boat.
    • Plenty of Soft drinks and water must be made readily available for your guests. If you have service staff, we request they offer to your guests hourly.
    • The boat/agent will take no responsibility for loss or damage of personal belongings.
    • If the skipper or any member of the crew observe anti social or potentially dangerous behavior by passengers disembarking from other vessels or any other person/s at the point of disembarkation the skipper may alter the drop off point or wait until the problem has cleared. The skipper will not risk your passenger’s safety by dropping them into a dangerous situation or environment nor will they add to the problem. If other arrangements have been made by you relating to other activities or transport after the charter we accept no liability for   cost incurred by the passengers because of their delay in this situation. The skipper will act in a reasonable and responsible manner to try to ensure the safety of our passengers, crew and the general public within the vicinity, within reason.
    • On evening charters, swimming is not permitted from the boat.  For Day charters, please advise us if you or your guests are planning to swim from the vessel.
