Who is selling "Serenity"?
"Serenity" is offered by its listing brokerage through the YATCO MLS. Greg Gaus of Double G Yacht Sales represents you, the buyer: independent advice on price, survey attendance, and negotiation, paid from the existing listing commission - never by you.

What does it cost to run a 125-foot motor yacht?
As of 2026, industry estimates for a crewed 125-footer typically run high six figures to low seven figures per year, with a crew of about six to seven, covering crew, fuel, insurance, dockage, and maintenance. Westport's US-based build and parts support keep long-term costs predictable. Greg can build a realistic operating budget for this yacht before you offer.

Where can I see "Serenity"?
She is lying in Port Washington, New York and shows by appointment through your broker. Contact Double G Yacht Sales to arrange a private showing.

How does the purchase process work?
Accepted offer, then a survey and sea trial contingency of typically 7 to 14 days. Greg - a licensed captain with 20+ years at sea - attends the survey and sea trial personally and manages everything through closing.

How much is Florida sales tax on a yacht?
Florida charges 6% sales tax on boats but caps the total at $18,000 per vessel regardless of price - one of the most favorable regimes in the US. Out-of-state buyers who remove the vessel within the statutory window may qualify for an exemption.

How fast is she, and what is the range?
Cruise around 20 knots, top speed about 25 knots and 6,940 gallons of fuel with twin MTU 16V2000 M96L, 2,600 hp each - comfortable Florida-Bahamas legs and seasonal Caribbean runs.
