...but even on their website I read it as, if you have an ok time, please leave $100-$150... I'd expect to have more then an ok time, and I'd at least be prepared to tip a little more then the suggested amount.
I see suggested 10%-15% as a fairly wide spread covering a wide range of experiences. The way I read it, $100 is for the service that is barely OK, and $150 is for the service that is very, very good. If the service is sub par (can't really come up with a solid example from experience and hopefully won't encounter it this time), I see nothing wrong with tipping less that $100. If the service is in their own words "outstanding" (again, not sure what constitutes going above and beyond on a liveaboard), I see nothing wrong with tipping more than $150. I wouldn't consider tipping on the higher end for sub par service a good tipping practice.
I personally would be coming expecting to leave $150 (that's what I factored in when planning the trip) for the great service, and don't see it as a light tip at all. I appreciate BB's specifying the expected range on their website, it does help with planning.
