How to make a career in yacht racing

No not required.  I'll give you 2 examples. 1. Lad learns to sail quite well then gets RYA qualified.  He then spends a summer teaching at Minorca or similar, does well and so is asked to do it again.  Next year they ask him to manage the facility, which he does.  Following year they ask him to manage new facility in Caribean, facility gets bigger and he earns more. 2. Lad learns to sail quite well, gets RYA qualified and teaches at Minorca or similar.  Following year does it again but at a facility in Caribean.  Meets rich american who like sailing so buys small criuser and lad crews for him at big events around Caribean for the summer.  The following year the rich american buys bigger boat and asks lad to look after it and deliver it to various regattas on eastern seaboard.  The following year american buys even bigger boat and lad looks after it, except he has it built in Europe so lad has to take delivery and sail trans Atlantic.  American now has 80 footer and lad has girlfriend and sister on board as cook and crew and spends most of his time sailing between regattas on either side of Atlantic.  When owner is not using boat the lad invites his parents for Caribean cruises.

Both are true stories.
