Update from Dive Assure:
They confirmed a sinking/wrecking would be the responsibility of the liveaboard - they will (should) have appropriate insurance coverage to cover them for such an event, including their need to compensate their customers. Another reason to go with reputable operators, and probably wise to ask if they have insurance. You can never assume in some countries... I then asked about the airfare, hotels, and other incidentals, etc., that were booked for before/after the liveaboard that cannot be canceled/refunded. He confirmed that if the liveaboard will not/did not provide compensation for this, trip cancellations and interruptions would be covered, based on the regular terms of the policy, with a 20% co-insurance as this is still a trip interruption/cancellation.
This is also a very, very good reason to book your travel on your credit card and why I often book through an agency for liveaboards and resorts that only accept wire transfers and sometimes PayPal. Not only do I get points for my credit card for travel bonuses, I have the protection of chargeback if the liveaboard operator tries to duck the compensation for the liveaboard itself if something went terribly wrong. I also always book hotels and airfare with my credit card so that I can possibly claim trip cancel/interruption through them as an alternative.
As for the OP, I would try to get compensation from the liveaboard company for as much as you can first. Since DAN Travel Insurance is failing you on the trip interruption/cancellation part for a sinking, I would try to seek trip interruption/cancellation from the credit card company you used to pay for the hotels/airfare...and possibly look into getting Dive Assure next time instead. I have always thought that they are much more encompassing, especially for divers.
Below is relevant if the liveaboard fights you or drags their feet on paying you back on what you spent for a non-delivered service like if the liveaboard sunk before or while you were on it....Please note the underlined portion on the dating as that is what will likely apply for liveaboards based on how early we book, etc.
