How the Season Flows

We Handle It,
Fall Through Spring

Fall

Drop Off & Winterize

Bring it in as the season ends. We run the full winterization checklist so it's ready for the off-season.

Winter

Protected All Winter

Fogged, stabilized and wrapped — your boat is protected from corrosion, fuel breakdown and the weather until you're ready to run again.

Spring

Commission & Splash

We de-winterize, check it over, and have it splash-ready — so your first weekend back is pure water time.

Common Questions

Winterization,
Answered

?

Do I really need to winterize in California?

Yes. Even in the mild Delta climate, months of layup invite fuel breakdown, corrosion and battery drain — and cold snaps bring real freeze risk. Winterizing protects the engine, systems and resale value.

?

What does winterization include?

A full layup: engine fogging, antifreeze through the cooling system, fuel stabilization, oil & filter change, draining water systems, battery service, drive lubrication, and shrink-wrap or a fitted cover.

?

Do you offer spring commissioning?

Yes. When the season returns we de-winterize, check everything over and get your boat splash-ready, so your first weekend back is pure water time.

?

When should I book?

Early fall. Off-season slots are limited and fill quickly, so reserving early secures your service date before they're gone.
