Advice about entering the maritime industry

Hello everyone,
Am considering trying to get a job on yachts as a deckhand while I am living and working in England and hoping to be able to work around Europe. I’m thinking about getting my STCW95 certificate and doing a few other courses and then looking for deckhand positions (have no previous sailing experience). If anyone could offer any advice on the pros and cons of this type of work (I’m thinking I might do it for a few years, start at the bottom and work my way up) and what they think of my approach, and what the job market is like at the moment, I’d be much obliged. Cheers!
