. Matari, your recommendations are sound but, for the reasons you provided, it is unlikely that many yacht-borne helicopters are exposed to all of this treatment - save perhaps the daily wash down. Maybe aboard Paul Allen's craft the MY Octopus (
see post #1) with its spacious helideck replete with hangar but, on many of the smaller yachts, I doubt it. Some may of course retreat to shore in order to perform these tasks.
Oh, and I've never heard of spraying anything into the exhaust stack of a C20...would be interested to hear what that was about.
Well, if it wasn't a spray then it was something to do with either or both the exhaust and air inlets. Perhaps the covers were impregnated with something which was supposed to protect the engine from corrosion? [This is me trying to remember the details of an ad I read in the US c. 1980!].
Unfortunately, specific information on helicopter ops will be few and far between. The superyachting world, particularly the high end, involves a lot of privicy and confidentiality agreements.
The thing with PPRuNe is that they can sign up as 'Joe Bloggs' and are not obliged to divulge specific details. What we are interested in is general information (preferably based on experience) relating to yacht-borne helicopter operations.
There may also be some flyers whose past experience includes such ops.
