The Sunshine Catamaran is one of the sets released in the summer of 2017.
Official LEGO.com DescriptionEdit
Enjoy a supercool cruise on board the luxury catamaran! Relax on the deck in the sunshine and then cool off in the pool. Get the best view from the bridge and spot Liam on the personal water scooter towing Stephanie on the banana boat—two friendly dolphins have come to play with them! Head below deck to chill out in the lounge and gaze through the catamaran's clear bottom. Then head to bed ready for another exciting day at sea!
