Boat Service & Storage Facility In Grand Haven, MI

Jefferson Beach Yacht Sales’ Grand Haven service facility sits just down the road from Grand Isle Marina in the Grand Haven Storage complex - home to year‑round storage (heated in winter) and direct, on‑the‑spot access to an 80‑ton travel lift for fast haul‑outs and around‑the‑clock capability.

Factory‑trained technicians handle warranty and retail work on and off site, from diesel and gas engine maintenance to electronics, stabilization, and onboard systems—backed by certifications with major brands including Volvo Penta, Mercury/MerCruiser, Yamaha, Garmin, Raymarine, Seakeeper, Dometic, Kohler, and Williams Jet Tenders.

As an approved Williams Jet Tenders dealer at Grand Haven, the team can service your tender alongside the mothership for a one‑stop experience.

And because the shop is connected to JBYS’s broader Great Lakes service network—with mobile service vehicles ready to come to you - you get responsive support at the dock, on the hard, or wherever your schedule takes you.
