I’m all fired up on handplanes. The beach below my house, Salt Creek, is madness in the summer and long stretches of it are blackballed from board surfing. A perfect alternative is bodysurfing using hand planes, miniature boards that lift you out of the water, set you trimming, and give a measure of control otherwise missing.
You can buy beautiful hand planes — state of the art Brownfish models go for $140 — but the little sticks beg to be done it yourself. Since we’re talking about a decidely low-fi pursuit, any old plank will do, so long as it’s well sealed.
