Boat Winterization in Sag Harbor

60-prestige-yacht-2

Skipping this step is a costly gamble. Water left in an engine or pipe can freeze, expand, and crack the parts around it. A cracked block can cost more than a new season of dockage. Yacht Hampton's on-site team handles winterization the right way, here on the East End.

 

What winterization protects

We work through each system that water can damage:

  • Engine: drain the block, run antifreeze through it, and fog the inside.

  • Fuel system: add stabilizer so the fuel does not break down.

  • Freshwater and plumbing: drain the tanks, lines, and head, then add antifreeze.

  • Batteries: service and store them so they hold a charge.

Done by our own team

Our service crew is on site at the marina all year. They know boats common to local waters, and they do this work every fall. You are not handing your boat to a far-off shop and hoping for the best.

Book it with storage

This service pairs naturally with the off-season. Many owners bundle it with a wrap and storage in one hand-off at our boat storage hub. See our winter storage rates, winter boat storage, and shrink wrapping options. In spring, we de-winterize during your spring launch, so the boat is ready to run.

Timing

Book before the first hard freeze. Once temperatures drop below the mid 30s at night, water can start to do damage. Early fall is the safe window. Call for a quote and we will set a date.
