PRODUCT DESCRIPTION The Grom inflatable is based on the same proven overall design, outline, and features of the Crossover Inflatable scaled to an 80 for kids. The single fin in the back combined with the center fin provides exceptional lateral resistance when used with a sail, making this a great windsurfing board and wing-surf board. The mast insert is flush with the deck of the board, so there is no bulky plastic to get in the way when the sail is not attached. The Grom features a single-layer dropstitch construction, making it lightweight and easy to handle. Let your kids explore as far as their curiosity takes them with this stable and efficient 3-in-1 inflatable.
