Large Birds Are Notably Adept at Gliding
"Large birds are notably adept at gliding, including: Albatross. Condor. Vulture." -Wikipedia
"Large boards are notably adept at gliding, including: The Cash-Yew II, the Earl, the Walks on Water, and the Lumberjack." -Almond Surfboards
When it comes to surfboards with maximum glide, you simply can't replace length. No matter how thick or wide a surfboard gets, a longer board will always win when it comes to superior glide and earliest wave-catching.
