Since surfer Kirk Cottrell founded the Island chain (five other shops are located along Florida's east coast) 20 years ago, local surfers have made the Deerfield Beach store their supply headquarters. Name-brand boards by Rusty, Local Motion, Natural Art, and other manufacturers line the walls and railing of the upstairs loft. And those are just the short boards; seven or eight brands of long boards, including Hobie and Stewart, are here, too. Also in the lineup are boards by carver-shaper Mike Pechonis, a local whose work is sold under the Byrne name. Of course a surf shop doesn't live by boards alone, and Island offers a full lineup of wet suits, ankle leashes, and shorts. Even surfboard manufacturers have expanded their sales bases, offering clothing, sunglasses, hats, and watches. Island carries the latest lines, and for surfer wannabes the shop offers board rentals and free surf lessons.
