Owner Experience Review
Owners who use the 670fromBertram Yachtas a tournament-scale convertible praise its 168 ft² cockpit with bait-prep, fishbox, and rod stowage, and more importantly the way the deep-V hull keeps the ride dry and composed in offshore chop. Reported cruise sits around 32–34 knots with top speeds near 37–38 knots depending on MTU/Cat power, giving the boat real pace for its size while remaining confident and stable offshore; the tradeoff is that its length and over-18-foot beam can make tight-marina maneuvering challenging for less experienced helms.
Day to day, the layout feels purpose-built for both fishing and family use. Four staterooms and four heads, including a full-beam master, deliver unusually generous accommodations for a convertible, while the salon opens to the galley with a bar for guests. One of the model’s distinctive touches is the spiral staircase from the cockpit to the flybridge, which improves flow during active fishing or when entertaining.
Owners planning extended cruising or owner-operated passages value the volume and fuel capacity, but they also budget for the realities of big horsepower. Fuel burn is high and overall operating and maintenance costs are above average for twin 1,800–2,000 hp diesels; factory offerings included MTU 16V2000s and high-power Caterpillars. On older 2001–2009 hulls, brokers frequently note major-ticket refits—electronics upgrades and stabilizer/SeaKeeper installs among them—and major diesel work and parts can be a material expense.
Pros and Cons
- Deep-V hull delivers a notably dry, confident ride offshore.
- Fast for its size, with reported 32–34-knot cruise and 37–38-knot top speeds depending on power.
- Four staterooms with a full-beam master, an open salon/galley with bar, and a cockpit-to-flybridge spiral staircase support extended cruising and entertaining.
- High fuel burn and above-average operating costs with twin 1,800–2,000 hp diesels.
- Tight-quarters maneuvering can challenge inexperienced helms given the length and 18-plus-foot beam.
- Older hulls often require high-ticket refits and major diesel work, from electronics to stabilizers.
