Sound familiar?
Your kids have the energy of a thousand suns. You burn out after 30 minutes. So you cut the adventure short — again — because your arms gave up, not your spirit.
"You guys go ahead." It's not that they don't like the water. It's that paddling for 45 minutes in the wind isn't anyone's idea of relaxation. So now it's just you and the kids. Or more likely, nobody goes.
You see the island. The cove. The river bend. Your kids point at it. You say "maybe next time." But next time never comes, because getting there means 40 minutes of hard paddling each way.
Without the ability to go far or go fast, paddleboarding feels like standing in a parking lot on water. They'd rather be on their phones. Can you blame them?
Two boards, two paddles, life vests, the roof rack, the dry bags. It all sits there, waiting for the weekend that's easy enough, warm enough, calm enough. That weekend comes twice a year.
The fix is simpler than you think
Boost Fin Plus is a small electric fin with a folding propeller. It slides into any standard fin box in 5 minutes. No drilling, no modifications, no engineering degree.
Press the waterproof remote on your wrist, and the motor does the paddling. You steer. You look around. You actually talk to your kids instead of gasping for air.

Picture this
7 AM. The lake is glass. You slide the fins in, load the kids on the front. You're at the far shore before anyone else is awake. You find a beach. You make breakfast on a camp stove. The kids find frogs. Your partner reads a book. You paddle back when you feel like it.
You rented a house on the coast. Last year, you paddled 200 meters and called it a day. This year, you cruise the coastline. You find a sea cave. The kids lose their minds. You take photos from angles you've never seen. The rental boards fit your fin in 5 minutes.
Dinner's done. The light is golden. "Want to go out?" Everyone says yes — because they know it's easy. Twenty minutes on the water, no effort, just gliding. The kids trail their hands in the water. You and your partner actually talk.

This is the part of the day you'll remember in ten years.
Real families. Real weekends.
“Our boards sat in the garage for 8 months. I'm not exaggerating. We bought the bundle in April, and we've been out every single weekend since. My wife — who said she was 'over paddleboarding' — now asks ME if we're going.”

“We explored 6 miles of coastline in Maui with two rental SUPs and our Boost Fins. My 9-year-old still talks about the sea turtle we found. Without the fins, we would have turned back after half a mile.”

“I'm not athletic. My husband is. That used to mean paddleboarding was 'his thing.' Now it's our thing. The fin makes me just as fast as him, and I actually enjoy it instead of dreading the paddle back.”

You didn't buy those boards to store them. You bought them because you imagined mornings on the lake, afternoons exploring, sunsets on the water — together. Boost makes that picture real. Not someday. This Saturday.
