Design and Construction
The hull is solid fiberglass, a construction that requires only minimal maintenance during the sailing season. Dynamique offered the 47 with different keel alternatives, and the choice materially affects where the boat can go. Depending on load, the shallow-draft fin version draws about 5.4 to 5.7 feet and can enter most marinas, while the deeper fin keel draws roughly 7.05 to 7.35 feet and limits the boat to major marinas.
The lead-ballasted hull has a ballast ratio of 35 percent. That’s higher than 46 percent of comparable designs, though still just below average for resistance to heeling. A displacement-length ratio of 193 puts the design among the “moderate racers,” and 69 percent of similar sailboats are heavier.
Her length-beam ratio of 3.23 makes her roomier than 73 percent of similar designs, a distinction reflected in the accommodations below.
Rig, Performance, and Handling
The Dynamique 47 is a masthead sloop. The rig’s simplicity allows a given sail area to be carried lower and with less heeling moment than a fractional layout. The working sail plan—mainsail and jib—covers 718 square feet.
The standing running gear is sized accordingly. Jib and genoa sheets are about 46 feet long and 5/8 inch in diameter. The mainsheet is 115 feet of the same diameter, while the spinnaker sheet measures just over 101 feet. A single Perkins diesel may be fitted.
The theoretical hull speed is 8.4 knots. With a capsize screening value of 1.95, the boat could, by that formula alone, be accepted to participate in ocean races. Her Motion Comfort Ratio is 27.3, making her more comfortable than 27 percent of similar designs—a comfort value just below average. An immersion rate of about 1,942 pounds per inch points to a heavily loaded waterline.
The wetted surface of the underwater body is about 581 square feet.
Accommodations and Tankage
Below deck, the Dynamique 47 offers three or four cabins, six to eight berths, a galley, and a toilet facility. This interior volume follows directly from the beamy hull form.
Fresh-water capacity is 211 US gallons, while the fuel tank holds 105 US gallons. Those are generous figures for extended cruising without constant replenishment.
Refit and Ownership Considerations
The main ownership consideration is the keel chosen when the boat was built. The shallow-draft version will suit a coastal cruiser who values access to most marinas. A deep-draft example accepts the limitation to major marinas, along with fewer anchorage choices.
The solid-fiberglass hull keeps seasonal upkeep light. Large tank capacities also reduce the pressure for frequent upgrades when moving a boat from charter service into private use.
Verdict
The Dynamique 47 is a thoughtfully proportioned French cruiser-racer with genuine interior volume and ocean-capable screening numbers. Its main shortcoming is a Motion Comfort Ratio that falls below the median for its class. Buyers will want to choose the keel best suited to their home waters and cruising plans.
Pros
- Roomy three- or four-cabin layout with six to eight berths
- Low-maintenance solid-fiberglass hull
- Shallow-draft option providing access to most marinas
- Capsize screening value that could qualify the boat for ocean racing by that formula alone
Cons
- Motion Comfort Ratio just below average for the class
- Deep-draft keel limits marina and anchorage choices
