We chartered the dream catcher for a day with 2 families (10 of us). We went to Koh Phangan for the day and enjoyed fishing, stand up paddle boarding, snorkeling and swimming.
It was fabulous sailing across and back, kids were even allowed to sail. Great lunch organised by crew at a very picturesque restaurant (one of the better meals we had in Koh Samui). Would highly recommend. Expensive, but a fabulous day had by all.
