The Robertson and Caine Leopard 45 2017 vs Robertson and Caine Leopard 58 2011 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 58 2011 measures 57,7 feet overall (2011), giving it roughly 12,7 additional feet of deck space compared to the Robertson and Caine Leopard 45 2017 at 45,0 feet (2017). Weight tells a clearer story for trailering families: the Robertson and Caine Leopard 58 2011 tips the scales at 80 469 lbs — 48 502 lbs less than the Robertson and Caine Leopard 45 2017 at 31 967 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 75 hp, the Robertson and Caine Leopard 58 2011 has a 30-hp advantage over the Robertson and Caine Leopard 45 2017's 45-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 58 2011 carries 238 gallons versus 185 gallons in the Robertson and Caine Leopard 45 2017. 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 58 2011 is rated for 17 passengers, while the Robertson and Caine Leopard 45 2017 caps at 13. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Robertson and Caine Leopard 58 2011 could be the deciding factor.
Displacement is where these two sailboats genuinely part ways. The Robertson and Caine Leopard 58 2011 displaces 80 469 lbs — a 48 502-lb difference over the Robertson and Caine Leopard 45 2017 at 31 967 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 58 2011 draws 6,0 ft, compared to 4,1 ft for the Robertson and Caine Leopard 45 2017. That 1,9-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.
The Robertson and Caine Leopard 45 2017 uses Sloop rigging. For auxiliary power the Robertson and Caine Leopard 58 2011 carries a 75-hp engine against 45 hp on the Robertson and Caine Leopard 45 2017. Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.
For extended cruising, water capacity matters: the Robertson and Caine Leopard 58 2011 carries 412 gallons versus 206 gallons on the Robertson and Caine Leopard 45 2017 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
Bottom line: The Robertson and Caine Leopard 58 2011 is the offshore and bluewater choice — at 80 469 lbs displacement and 58 ft it has the load capacity, range, and seakeeping for extended passages. The Robertson and Caine Leopard 45 2017 at 31 967 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.
