There is no such thing as insurance that will cover your gear left unattended on the beach, or in use. Maybe some full on yachting insurance but no travel insurance and no contents insurance will cover you. All insurance policies have clauses about your "duty of care" and some exclusion about sporting equipment while in use.
The simplest thing to do is make sure you have extra cover for your stuff outside your home, then take reasonable care of your stuff while you're travelling or using it. It's not hard.
Most policies have a limit per item and total amount limit. Mine is $1000 per item and $10,000 total. That's heaps for each kite or my mountain bike or other stuff I use each day or take away on holiday.
I used to take out additional cover on things when I travel overseas but I stopped doing that. When you consider that each item depreciates to zero over 2-3 years then it only makes financial sense to individually insure really expensive, really new things. Otherwise the value you get back in an insurance claim is hugely cancelled out by the cost of insurance.
I always take out travel insurance as soon as I book a trip if it includes airfares or other pre-payments more than a few hundred dollars. You can get insurance for $50-60 that covers a domestic trip. If you have to cancel the trip for any significant reason then the insurance will refund your money. If you don't have insurance then you rely on the good will of the airlines and accommodation providers.
Virgin don't refund, they give credits and the credits run out in 12 months. You can work around the 12 month thing but it's a pain.
