I'm keeping this alive in 2012.
I believe that sometimes the 10 to 15% suggested tip for liveaboards is too much. For example the Philippine Siren costs about 3450 for 10 days. That would amout to tips for all of the crew of $322 to $483 each a week. The boat takes 16 divers and has a crew of 12. I assume that they get paid something from their employer. Considering the pay scale in the Philippines, with degreed accountants and teachers earning $400 to $500 a month and Registered nurses earning $300 a month, I don't get tipping 4 to 6 times average professional salaries. Somehow I don't think that all of those tips are actually making it to the crew. I bet they could hire an 18 year old gal to clean for 250p a day plus food and lodging and that would be enough. Please explain the economics of this to me. Maybe the crew has to pay for their room and board and work for free?
I'm not sure we can judge it that way. In a world where athletes are paid MILLIONS to kick/throw/hit a ball around, who's to say DM/boat crew aren't supposedly to earn more than accountants/teachers? Is it any less professional to make sure the guests don't drown, get lost at sea or eat properly?
This amount did not come from my travel agent but in fact is from Luigi (or his FAQ writers
) and can be view on the Arenui FAQ page here:

I have been on many cruises of the traditional sort and the standard to tip is usually around $10-$15 per day per person that is divided among the crew. I have really been pondering that we are spending $11,000 for my wife and I to go on this trip and then looking at $1100-$!600 in tipping for 12 days on top of that. I guess my feelings are with the cost of the cruise being on the high end I would rather they charge even a little more up front and say that gratuities are included.
I guess I should read the info packs moreover then.

Let's be fair to say that higher end establishments tend to have better service, and thus the gratuities are higher. From presentation to which side to serve from etc, luxury is something I'm sure we all can enjoy.
I'd add that salaries aren't all that high and some places, the local crew get less than the foreign crew.
