The Robertson and Caine Leopard 42 2019 vs Robertson and Caine Leopard 45 2017 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 45 2017 measures 45,0 feet overall (2017), giving it roughly 3,3 additional feet of deck space compared to the Robertson and Caine Leopard 42 2019 at 41,7 feet (2019). Weight tells a clearer story for trailering families: the Robertson and Caine Leopard 45 2017 tips the scales at 31 967 lbs — 4 482 lbs less than the Robertson and Caine Leopard 42 2019 at 27 485 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.

Both boats share a closely matched power ceiling — 45 hp for the Robertson and Caine Leopard 42 2019 and 45 hp for the Robertson and Caine Leopard 45 2017. 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 Robertson and Caine Leopard 45 2017 carries 185 gallons versus 158 gallons in the Robertson and Caine Leopard 42 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 45 2017 is rated for 13 passengers, while the Robertson and Caine Leopard 42 2019 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Robertson and Caine Leopard 45 2017 could be the deciding factor.

Displacement is where these two sailboats genuinely part ways. The Robertson and Caine Leopard 45 2017 displaces 31 967 lbs — a 4 482-lb difference over the Robertson and Caine Leopard 42 2019 at 27 485 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.

Both boats draw a similar depth — 4,7 ft and 4,1 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.

The Robertson and Caine Leopard 42 2019 uses Sloop rigging.

For extended cruising, water capacity matters: the Robertson and Caine Leopard 45 2017 carries 206 gallons versus 174 gallons on the Robertson and Caine Leopard 42 2019 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
