The first thing that caught my eye was a deep gutter that rims the cockpit sole to let water get out from underfoot as soon as possible. It drains into a six-gallon sump at the center of the transom, discharging overboard through scuppers near the centerline, where they are less likely to be immersed as the yacht rolls. An eight-foot-long fishbox in the sole is removable for access to the lazarette and steering gear, and an icemaker can be plumbed into the fishbox or a livewell in the transom.

The full bait-prep station along the Bertram 670's port forward bulkhead, with a sink and cutting board, was pressed into service as our catch was cleaned and filleted. If there had been more time for fishing, we might have had to utilize the big freezer on the starboard side. Above it, just aft of a circular stair up to the flying bridge, there's a nifty, vertical rod stowage space complete with freshwater washdown.

Our lengthy voyage did allow plenty of time to appreciate the comfortable Murray Brothers helm and companion seats. Both are on a platform about a foot above the bridge deck for a better view of the cockpit and for better sight lines forward over the lounge seating area. A wing control station affords an unobstructed view along the entire port side to ease docking.

The helm is Palm Beach-style with a drop-down console fitted with a dual-display Northstar 952X GPS and two Black Box daylight-readable displays. Putting the console in the down position lets the captain converse with guests in the forward lounge and provides a weather-tight enclosure for the electronics. The Furuno color LCD depthsounder, B&G tridata displays, Robertson autopilot, and DDEC displays remain in view, even when the console is down.

Forward of the helm, a cocktail table is normally installed in the center of the seating area, but our test boat had been ordered without it. While this makes the space roomier for dockside entertaining, it leaves little for guests to grab onto when the yacht is underway. In the interest of safety, I believe handholds should be added around the perimeter of the lounge.

As comfortable as the flying bridge was, most of the folks onboard (a contingent of Bertram marketing and salespeople) opted to pass the time relaxing in the saloon, curled up on the spacious settee or stretched out in the roomy dinette seating area. Bertram has taken care to keep the accommodations space as quiet and comfortable as possible, not only with thermal and acoustic insulation lining the machinery space, but also by locating all pumps, motors, and other noisy components inside or aft of the engine room. To reduce airborne noise, the engine room is completely sealed, with sealed chine boxes providing fore and aft chase ways for plumbing and electrical systems. Cruising at more than 30 mph, we measured comfortable sound levels: just over 70 dB in the saloon (normal conversation is about 65 dB). Even at WOT, over 40 mph, we recorded a respectable 78 dB.

Interior fit and finish reflect the Ferretti influence (Ferretti purchased Bertram a few years ago) with fine joinery and hand-selected wood grains. Workmanship in the engine room is equally meticulous, with all inner hull surfaces vacuum-bagged, faired, and finished with Awlgrip. Twin 1,800-hp DDC-MTU 16V2000 diesel inboards (which, while on our test boat, are no longer offered) had a good two feet of clear space between them and handholds on either side in case they need attention during adverse conditions. Filters, dipsticks, and other access points are easily accessible, as are most auxiliary systems. The lone exception might be the twin Kohler gensets, in hushboxes tucked well aft under the cockpit sole. Routine access appears limited, but for major repairs a large section of the cockpit sole unbolts, providing excellent access from above.

The new 670 Convertible has everything you'd expect from the respected Bertram marque. And like a good friend, she proved to be a great travel companion. Comfortable, capable, and well-built, she's ready for anything, from serious tournament action to a relaxing family cruise.
