The push toward electric-powered boats marches forward. Robert Allan Ltd., a naval architecture and marine engineering firm out of Vancouver, British Columbia, has released its plans for an all-electric, 52-foot, aluminum pilot boat. The RAlly 1600-E has a top speed of 20 knots and a range of 5 nautical miles.

According to the company’s website, “This boat is ideal for short run applications of 5 nautical miles (NM) or less and where there is time between jobs to recharge the batteries. Pilot boats typically run at or near top speed with the pilot on board, then loiter for some time and may return at a more efficient medium speed. In this mixed-use scenario with a 5-nautical-mile run, the RAlly 1600-E can complete a full operation totally on batteries with 30 percent of nominal battery capacity to spare.”

The RAlly 1600-E is powered by a pair of 750-volt, 500-kW electric motors that drive through standard ZF or Twin Disc 3:1 reverse/reduction gears to conventional shafts and 33-inch propellers. Robert Allan Ltd. adds, “Twin small auxiliary generators give “get home” and range extension capability but are normally not running. With a top speed of 20 knots and quiet, emission-free running, this vessel will convey pilots at speed and in style. The environmental impact of operations and operating costs are also significantly reduced.”
