The Robertson and Caine Leopard 46 2018 vs Robertson and Caine Leopard 50 2019 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.
Size is the most obvious dividing line here. The Robertson and Caine Leopard 50 2019 measures 50,6 feet overall (2019), giving it roughly 4,2 additional feet of deck space compared to the Robertson and Caine Leopard 46 2018 at 46,4 feet (2018). Weight tells a clearer story for trailering families: the Robertson and Caine Leopard 50 2019 tips the scales at 57 320 lbs — 20 375 lbs less than the Robertson and Caine Leopard 46 2018 at 36 945 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 Robertson and Caine Leopard 46 2018 has a 193-hp advantage over the Robertson and Caine Leopard 50 2019's 57-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Robertson and Caine Leopard 46 2018 carries 488 gallons versus 243 gallons in the Robertson and Caine Leopard 50 2019. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Robertson and Caine Leopard 50 2019 is rated for 15 passengers, while the Robertson and Caine Leopard 46 2018 caps at 14. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Robertson and Caine Leopard 50 2019 could be the deciding factor.
Displacement is where these two sailboats genuinely part ways. The Robertson and Caine Leopard 50 2019 displaces 57 320 lbs — a 20 375-lb difference over the Robertson and Caine Leopard 46 2018 at 36 945 lbs. That gap separates two entirely different categories of sailing: the heavier boat is built for offshore passage-making and load-carrying, while the lighter hull rewards performance sailing and easier handling in lighter air.
Draft is a practical consideration that many buyers underestimate until they're already at the marina. The Robertson and Caine Leopard 50 2019 draws 5,2 ft, compared to 3,1 ft for the Robertson and Caine Leopard 46 2018. That 2,1-foot difference affects which anchorages you can access, which haul-out facilities will take you, and how carefully you need to read the tide tables in shallower cruising grounds.
For auxiliary power the Robertson and Caine Leopard 46 2018 carries a 250-hp engine against 57 hp on the Robertson and Caine Leopard 50 2019. Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.
Bottom line: The Robertson and Caine Leopard 50 2019 is the offshore and bluewater choice — at 57 320 lbs displacement and 51 ft it has the load capacity, range, and seakeeping for extended passages. The Robertson and Caine Leopard 46 2018 at 36 945 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.
