The Viking Yachts 43 Convertible 2001 vs Viking Yachts 46 Billfish 2023 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
Both boats share a closely matched power ceiling — 680 hp for the Viking Yachts 43 Convertible 2001 and 700 hp for the Viking Yachts 46 Billfish 2023. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Viking Yachts 46 Billfish 2023 carries 709 gallons versus 6 gallons in the Viking Yachts 43 Convertible 2001. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 13 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: The Viking Yachts 46 Billfish 2023 at 45,6 ft is the right call if deck space, comfort, and entertaining are top of your list. The Viking Yachts 43 Convertible 2001 at 43,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
