What's included with every boat

You're not just buying a hull. You're buying the help around it.

Anybody can sell you a boat. Here's what comes with it when you buy from a family that's been on the water since 1974.

Included · 01

On-water captain's training

Before you ever head out alone, one of our captains rides with you. We cover docking, trailering, trim, and the quirks of your specific lake until you're genuinely comfortable at the helm, not just handed the keys.

First trip outNo charge
Included · 02

Delivered ready to run

Your boat arrives fueled, detailed, and rigged for how you'll actually use it. Electronics paired, safety gear aboard, registration sorted. Back the trailer down and go, no scramble the morning of your first trip.

Fueled & detailedRigged for your lake
Included · 03

Service that comes to you

Three mobile service boats run the lake on weekends. A dead battery or a fouled prop doesn't end your Saturday, we meet you at your slip or out on the water and get you running again.

Included · 04

A slip with your name on it

432 covered slips across our docks mean your boat lives at the marina, ready when you are. No back-lot storage, no two-hour launch line on a holiday weekend, it's already in the water.

432 covered slipsAlways in the water
Included · 05

In-house certified techs

The people who service your boat work here and know it. Factory-certified and on staff, never subcontracted out to whoever's cheapest that week. The same hands, season after season.

We value your trade and walk you through financing before you sign anything, so the number you see is the number you pay. No surprises in the back office, no pressure at the table.
