The unsinkable legend that is Boston Whaler continues with the 305 Conquest, a heavily built 30-foot Express designed for serious anglers with a yen for quality. The 305 is a refinement of the popular 295 Conquest (1999–2003) with a larger cockpit, and updated interior, and a redesigned helm and transom. The Conquest’s list of fishing features begins with plenty of rod storage (under the gunwales and inside the cabin) and includes a 24-gallon transom livewell, cockpit rigging station, two insulated in-deck fish boxes with pump-outs, and an enormous hatch in the sole that provides unprecedented access to the bilge. Visibility from the 305’s raised bridge deck is excellent, and a comfortable lounge seat across from the helm seats two guests. Below, the Conquest sleeps four adults—two in the forward V-berth and two more in the mid cabin double berth. Cherrywood cabinets and faux granite counters highlight the galley. Additional features include a bow pulpit, wide side decks, and a hideaway bench seat that pulls out from the transom. Note that a hardtop is standard. No lightweight, twin outboards will deliver a top speed of 32–33 k
