Generally, a 15% tip is expected. The tip is divided between the captain and the partner on most ships. The friend gets a little more. Only large deep-sea ships will have more than one sailor and it's common enough for you to know how to handle it.
With two sailors and a captain directing the trip, tips can be confusing and the tip breakdown is different from ship to ship. On large ships it is normal to leave a tip of 20% of the price of the trip and the tips will be divided among the three crew members as they see fit. Giving an individual tip is a good way to show appreciation, but on some ships it is common to give a tip of 20%, with 10% for the captain and 5% for each sailor on deck. On other ships, the captain is paid enough in freight so that all the tips go to his sailors.
If you're worried about making a mistake, you can always ask if you should give the boat an individual tip or a lump sum and they'll be happy to let you know. Because tips seemed so ambiguous on this private yacht vacation, some travelers gave a 5% tip, while other charterers gave more than 25%, according to the Mediterranean Yacht Brokers Association (MYBA), regulated by the Mediterranean Yacht Brokers Association (MYBA). According to the MYBA, tips for yachts should range from 5% to 15%. You'll tip directly to the captain, either in cash, by check or even by bank transfer if you don't want to carry a significant amount of cash during your vacation.
Often, you can use your charter agent to transfer a tip to the captain. I think it's customary to give a standard tip of 10 to 20%. I'm good at a place out of 10, when my classmates are more courteous I hooked them, what grade are they in? that could very well increase the tip a bit. You should tip no matter how many fish you catch if the pairs are good.
20 PERCENT OF COLLEAGUES WORK TOO HARD NOT TO RECEIVE A TIP. 20% OF THE MANY SHIPS I WORKED ON MADE IT MANDATORY.
