Birchwood 310

Birchwood are actually offering two types of boat in a single shell.

Birchwood are actually offering two types of boat in a single shell. Parting with £74,300 ex VAT rewards you with a voluminous nine-knot inland waterways cruiser, fitted with a bow thruster and the smallest (78hp) diesel. The layout is ideal, either for a family or two couples, the inconvenience of converting the dinette more than compensated for by the significant extra privacy of sleeping cabins at opposite ends of the boat.

The second boat is a 23-knot semi-displacement powerboat, which can cruise from the Solent to the Channel Islands in less than five hours. And whichever Speed you want to cruise at, cooking and eating onboard the 310’s aft dinette and galley will be a real joy ­ there is more room than usual, plus plenty of worktop space.

In one area, there are strong echoes of our earlier 440 report ­ the standard of finish is adequate, but consistency and quality-control need to be considerably tightened up. The most obvious example on our test boat was the engineroom. Irrespective of the upheaval of new ownership, the original workforce should really be ensuring that fundamentally poor arRangements like this never see the light of day.

Consistency aside, the 310 has a lot to offer, such as comfortable handling in lumpy conditions, clearly laid-out instruments, and easy boarding from the side. But what really makes this boat is the layout ­ and for some buyers it will be difficult to beat.
