There are 3 ways to join TYW:

1. You gather a group of friends and 
book a yacht (the most common way). The price of the yacht is fixed and you split it between all crew members on board.

2. Grab one other friend and book a double cabin. You will then be placed on a yacht with other cabin bookers. This is a great, simple package which includes the price of a skipper, host and food! See here for more details about what is and isn't included.

3. Take a look at the Crew Finder where people who have already booked a yacht list their available spots to find extra crew. The Facebook Crew Finder Group is also a good tool to find spare spaces.
