How This Industrial Beast Saved a $120k Yacht Hull From Scrapyard Fate

When the custom teak swim platform started burning under my shipyard sander, the client’s face turned marina-red. Enter the Makita GV7000C – this 15.4-lb Titanium-coated savage stripped gelcoat at 0.001" consistency while rivals scarred fiberglass. For boat builders, metal fabricators, and restoration rebels, this isn’t a sander—it’s naval-grade redemption.
