M/Y Sea Class
A 1997 Christensen 155-footer refreshed in 2024 and ready to run.
"Sea Class" is a 1997 Christensen 155' motor yacht offered for sale at $9,500,000, lying Fort Lauderdale, Florida. South Florida is the deepest brokerage market in the world for large motor yachts, and condition separates the good buys from the money pits - which is why independent buyer representation matters more here than anywhere.
Power is twin 604BV12, 2,200 hp each, showing 500 hours. She cruises around 12 knots and tops out near 16 knots, carrying 12,000 gallons of fuel.
Accommodations run to 6 staterooms, plus crew quarters sleeping 10.

What does it cost to run a 155-foot motor yacht?
As of 2026, industry estimates for a crewed 155-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. Greg can build a realistic operating budget for this yacht before you offer.
Where can I see "Sea Class"?

How does the purchase process work?

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.

Price the refit into the offer, not after it.
At 29 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 Sea Class he can scope the work, get Fort Lauderdale yard numbers and build them into the price.
