GOOD TO THE BONE. The 340I's ride and construction can take on Neptune's nastiest. Its three-piece hull, deck, and liner are joined with through-bolts and fiberglass to create a rugged, watertight seal, as well as a secure toe-kick around the boat. Bolted through hard beds, the Yanmars will stay aligned for the long haul. Even the sea strainers are bolted through aluminum plate - the proper way to install hefty bronze hardware. All the mechanicals are easily serviced by raising the console front. Lift one of the three strut-assisted, piano-hinged hatch lids forward and note the deep gutter and thick gasket that protect the lockable rod stowage and overboard-draining fishboxes from spray. (Macerator pumps, often a standard on other boats, are $350 each on the 340I.) Now close the lid and jump on it. Like the hull itself, the hatch lids are internally stiffened with Divinycell, a weight-saving, closed-cell foam that inhibits flex. That, combined with wooden inserts installed where the hinges fasten, ensures that the hinge bolts won't spring loose over time.
