Poisonous

paints are often used to fight barnacles, but now scientists may have found a better solution.

Seaway, the Slovenian builder of 33- to 65-foot hybrid yachts, plans to debut its flybridge—the Greenline 45 Fly—at the Miami International Boat Show in February. The 45 Fly joins the 48 and 65 in the builder’s flybridge range. It has a pair of 220-hp Volvo Penta D3 diesels with conventional shafts and propellers. The shafts also have inline, clutched electric motors that spin the shafts under electric-only propulsion and charge the lithium-ion battery bank, which also recharges by shore power or via the topside solar panels.

Top electric-only speed is 6 knots, with a cruise around 4 knots. The electric-only range should be 15 to 20 nautical miles at 4 knots. Top speed with the Volvo Pentas is 25 knots.

The 45 Fly’s hard-edged, sporty styling is by J&J Design in Slovenia. Marco Casali of Italy’s Too Design created the interior. The guest stateroom has an island queen-size berth in the bow, while the amidships master stateroom has an island king. Each has an ensuite head with enclosed shower.

Outside, the 45 Fly’s cockpit has a teak swim platform and a transom grill. The flybridge has additional cooking space, lounge seating and a helm station. Base price for the 45 Fly is $575,000.
