Can Double G represent me as the buyer?
Yes. Greg Gaus spent 7 years as an in-house Westport broker and more than 20 years as a professional captain, and attends survey and sea trial personally. On a brokerage purchase the commission is paid by the seller.
How much is Florida sales tax on a yacht?
Florida charges 6% sales tax on boats but caps the tax at $18,000 per vessel. Out-of-state buyers who remove the vessel within the statutory window may qualify for an exemption; confirm with a tax advisor.
Buying a 37-year-old yacht?
Price the refit into the offer, not after it.
At 37 years, what a boat needs next matters as much as what she asks. Greg Gaus spent more than twenty years as a working captain and has managed refits on Westport 40Ms and 112s and a Viking 92. Before you offer on Mary Kathlene he can scope the work, get Fort Lauderdale yard numbers and build them into the price.
