Really? "Most"? You've done a survey? .
Boat operators like happy crew.
Happy crew are treated well and paid/tipped well
Unhappy crew = unhappy passengers. Operators try to avoid that by making there tipping policies well known.
Here's a few examples. Not a "survey" but this is direct from these operators websites..... Hope this helps.
Note I know there are more liveaboards than this. But this is a good basis of some well known liveaboards.

How do the tips work?
Tips are voluntary and performance based. We recommend a
10% gratuity. The Captain will have a basket for tips when
tabs are settled at the end of your trip.
Who gets the tips?
The tips are shared equally between the crew.

Nassau Information
What is the recommended gratuity? The live-aboard business is a service industry, and although the general public is seldom aware of it, gratuities are a major part of a crewmember's salary. Few other recreational activities rely so heavily upon the professionals in charge for your enjoyment and safety. A gratuity of 15% is customary, but many leave more when they feel the service was outstanding. If you are disappointed with the service, you should inform the Captain of your feelings right away so he may rectify the situation.

GRATUITIES
Crew gratuities are not included in the charter. We believe gratuities should be voluntary and based upon
the quality of service the crew has provided. When settling your account at the end of your stay, the
Captain will have an envelope for gratuities that will be divided equally among the crew. Payment may be
made by cash, traveler’s checks or credit card
Peter Hughes Dancer Fleet
IS IT CUSTOMARY TO OFFER A GRATUITY TO THE
CREW?
Aboard the Wind Dancer, gratuities are not included. We
prefer that our guests’ reward our crew based on performance.
If the crew performs to your expectations, we suggest
that a gratuity of approximately 10% of the published
package price be considered normal aboard a live aboard
dive yacht. Payment of gratuities is entirely at the discretion
of the guest. Payment of gratuities can be by cash,
traveler’s check, or credit card (Visa or MasterCard). The
crew greatly appreciate cash as local banking fees and
government taxes for traveler’s checks and credit card
processing reduce the amount of gratuity left on a credit
card up to 35% in some destinations.
When in Costa Rica, it is a local practice that a 10% tip
is added to hotel and restaurant bills in the major tourist
areas. Where this charge is not added, it is customary to
tip 10% - 15%.
