The Four Winns HD1 OB RS 2021 vs Four Winns HD1 RS 2021 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.
On paper these two are close siblings in the size department — Four Winns HD1 OB RS 2021 at 18,6 ft versus Four Winns HD1 RS 2021 at 18,6 ft. Weight tells a clearer story for trailering families: the Four Winns HD1 RS 2021 tips the scales at 3 000 lbs — 300 lbs less than the Four Winns HD1 OB RS 2021 at 2 700 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.
The power gap is worth calling out. Rated to 250 hp, the Four Winns HD1 RS 2021 has a 160-hp advantage over the Four Winns HD1 OB RS 2021's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 32 gal and 32 gal — so range won't be a tiebreaker here.
Both boats are rated for 5 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: Performance buyers should lean toward the Four Winns HD1 RS 2021 and its 250-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Four Winns HD1 OB RS 2021 with its 90-hp rating is the more economical daily driver.
