When I read "Why use small SUPs? just prone surf a shortboard!",
My reply: "Just watch how shortboarders say that a 10% volume increase radically change things, and realize how that a tiny SUP is still twice the volume of a shortboard..."
Stumbled on this example today: "This surfboard, a 5’7 at 31L which is 10% more volume than I used to ride, totally changed my surfing experience"
