Neptunus 650

Our First Take: If you ask us, Neptunus absolutely nailed the lines on this versatile and well-thought-out Canadian-built express cruiser.

This 650, built by Ontario-based Neptunus Yachts, may look like just another pretty express cruiser, but she’s actually the product of some serious design. Her hull was developed by Tony Castro, a British naval architect with a reputation for turning out smooth rides. The deep-vee hullform with 19.5 degrees of deadrise at the transom should be quite seaworthy. Meanwhile those sleek lines I noted earlier were drawn out by Canada’s own Gregory C. Marshall. To my eye the boat resembles some sort of sleek pinniped—seal or sea lion, I’ll leave that up to you.

The boat’s interior has some features usually reserved for larger boats. In particular, a main-deck level galley and dining area complements the saloon. Down below, the accommodations level can be arranged with either two or three cabins. In either layout, the master is amidships and full beam, and features an impressively large head.

The boat’s engine room is accessed through either a gull-wing door in the transom or a hatch in the cockpit. The space was engineered for optimal access to the engines—either twin, 1,000-horsepower Caterpillar C-18 ACERTs, or the 1,136-horsepower upgrade. With the latter setup the boat can reportedly hit a top hop of 31.5 knots, and maintain a cruise of 26. The smaller engines only lose about a knot and half, according to Neptunus. Another nice touch regarding the boat’s practical design, the water/gas mixture from the genset discharges underwater, which helps keep things quiet. It’s that kind of attention to detail that helps set this boat apart. Have a look for yourself sometime soon. I think you’ll see what I’m talking about.
