Part of the Pursuit Offshore series — see how owners step up through the lineup.
The OS 445 is the largest boat Pursuit has ever built, but the thing that actually distinguishes it is not size — it is that the galley is upstairs. On almost every outboard cabin boat the cook goes below and misses the afternoon. Here the induction cooktop, the microwave and a 7.5 cubic-foot two-drawer refrigerator are all on the bridge deck, in the middle of the seating, under 26,000 BTU of air conditioning. Add two staterooms with doors that close, a head with a genuinely separate shower stall and private access from the primary, and you have a boat a family stays on rather than visits. Note the length carefully, though: 46 feet 6 inches includes the swim platform and the hull itself is 43 feet 10 inches. Your marina and your lift will each care about a different one of those.
Pursuit publishes its homework, and on this boat the homework is more interesting than usual. The bulletin ran 8/21/2023 at 36,969 pounds with four aboard. The recorded cruise is 25.9 mph at 4,000 rpm, quoted that way for consistency with the rest of the Offshore line — but the sheet does not behave itself. At 4,500 rpm the boat does 35.8 mph at 0.54 miles per gallon and 299 miles of range: ten miles an hour faster than the 4,000 line, at fractionally better economy, with 22 more miles in the tank. That is the number I would plan a long day around. And read the 3,000 rpm line as a warning — 12.2 mph at 29.6 gallons an hour is the boat stuck on the hump. Nursing a 37,000-pound hull to save fuel costs you fuel.
Here is the honest limit. Eleven feet of hardtop clearance above the waterline is sixteen inches more than the OS 405, and that is the number that decides whether you fit under your home bridge or into the building you wanted to store it in — measure before you commit. Nought to thirty in 16.4 seconds against the OS 405's 12.6 is the price of a heavier hull on the same 1,350-horsepower rating. And 600 gallons never buys more than about 300 miles here. If you want the accommodation with less boat to handle, look at the OS 405; if what you want is range rather than rooms, the OS 355 does 348 miles at 30 mph against this boat's 303. Buy the OS 445 because you need two real staterooms and a separate shower, not because it is the biggest one.

49.2 mph at 5,900 RPM on triple Yamaha 450 XTOs — the lowest published top speed in the current Pursuit range, and entirely a function of weight. The test was run on 8/21/2023 at 36,969 pounds, with four people, 618 gallons of fuel and full water and diesel tanks, on 16-5/8" x 19" XTO propellers.
Nought to thirty takes 16.4 seconds. This is the largest boat Pursuit has ever built, 30,718 pounds dry, carrying the same 1,350 horsepower as the lighter OS 405, which does 55.1 mph on it.
These are the two biggest boats Pursuit builds and they answer different questions.
The OS 445 is 46 feet 6 inches with the platform and 30,718 pounds dry: two staterooms, a bridge-deck galley, 600 gallons of fuel, 100 gallons of water and 49.2 mph on triple 450 XTOs.
The S 428 is 43 feet 9 inches and 26,519 pounds: a centre console with a forward berth in the console cabin, 518 gallons and 60.7 mph on quad 450 XTOs, which makes it the fastest boat Pursuit publishes a figure for.
If you are staying out nights, the OS 445 is the boat. If the days are long but they end at the dock, the S 428 gives you eleven more miles an hour and an open deck to fish from.
25.9 mph at 4,000 RPM, burning 52.0 gallons an hour for 0.50 miles per gallon and 277 miles of range on 90 percent of the test-condition fuel.
Read one line further down the sheet before you settle on that setting. At 4,500 RPM the OS 445 does 35.8 mph on 66.6 gallons an hour, returns 0.54 mpg and reaches 299 miles — faster, more efficient and longer-legged than the 4,000 RPM row, because the hull is fully on plane there and stops fighting itself.
Top speed is 49.2 mph, and the tank holds 600 gallons, the largest in the range.
Yes — two staterooms, which is unusual on an outboard boat of any size. The primary has an island-style berth with a queen memory-foam and innerspring mattress on a gas-assisted base with trunk storage, two hanging lockers and private head access. The starboard guest stateroom has a berth over storage, a settee and its own hanging locker.
There is one head compartment, with a separate stall shower, a Corian vanity and a 22-gallon holding tank. The bridge deck adds an electrically actuated table that converts to a further berth.
Fresh water is 100 gallons, and the interior runs solid-wood tongue-and-groove flooring with 16,000 BTU of cabin air conditioning.
