Nope - turn up and play. However you would be advised to buddy up with someone to avoid issues - eg proper equipment and preparation.
The first thing about preparing a craft for use in an environment without immediate rescue (eg safety boat) are float test (think I mentioned that one. A craft was lost at Liverpool, the engine stopped and it simply sank! Fortunately a member was there and rescued the pilot). Next is a good stress test of the engine and transmission. This is at least one hour of running at cruise engine speed with at least 15 minutes flat out. Include 5 minutes spraying the engine directly with a hose pipe - if this seems harsh wait until you're struggling to get it over hump in wind and waves - the spray can be huge and find the weak points in the ignition system right enough! Better to break down during test than 2 miles offshore! When you're ready, and if you want, we can do an online training session and cover these things and more.
