WHARF HOUSE TENACITY 58FT CRUISER
TENACITY WAS possibly the most high-tech boat at the show with electric propulsion, dual steering positions and a number of features designed to make life easier for the partially disabled owner.
Let’s start with the propulsion. The motor is by Piktronic, and is rated at 20kW at 48v. It’s powered by a tonne of batteries, giving 1250Ah (also of course at 48v). That’s a lot of battery capacity. Charging comes from a host of solar panels on the roof, and a 9kva Kohler generator. Other technology includes remote monitoring of the batteries and other systems, and an alarm.
Steering positions include the traditional tiller at the stern, but also wheel steering, inside, at the bow. To help with this, there are cameras on each side of the boat and two at the stern. Wharf House had to come up with their own control system for the two steering positions, as one wasn’t readily available on the market.
The fit-out includes a nicely inlaid table, and a pull-out system that allows the full-size freezer to make use of the otherwise dead corner of the galley. The cabin is in the middle of the boat, with a spacious walkthrough shower room beyond.
At the stern, there’s another cabin, with a single berth on one side and units opposite. This is where the batteries are housed.
Verdict: Electric propulsion, which could be the future of narrowboating.
