Built in France by Garcia Yachting, the boat was conceived specifically with the Northwest Passage in mind. Its rounded aluminium hull, internal ballast, and retractable centerboard favor steady passage-making over sparkling acceleration. The design also combines serious protection and self-sufficiency with the comfort and visibility of a raised deck saloon.
Design and Construction
The Exploration 45 measures just over 14 meters overall, with a beam near 14 feet 6 inches and a displacement of around 31,000 pounds. Its ballast ratio is 31 percent, while the moderate sail-area-to-displacement figure of roughly 15.9 reflects the boat’s emphasis on dependable cruising performance rather than quick acceleration.
The rounded aluminium hull carries internal ballast, and the integral centerboard retracts into the bilges. With the board raised, draft is 3 ft 5 in; lowered, it increases to 9 ft 2 in.
Serious compartmentation sets the Exploration 45 apart structurally. The hull has one watertight bulkhead at the bow and another at the stern, upstream of the helm system. Period surveys note that these two collision bulkheads reduce interior volume at both ends of the boat.
A protective skeg precedes the aluminium rudders, while a deep skeg houses and protects the propeller and shaft. The propeller shaft itself is wrapped in a fin. Each rudder has a composite sacrificial zone at the top, and there is no direct propeller wash over the rudders. The builder’s aluminium background shows in the watertight bulkheads and skeg-protected shaft, which give the boat a go-anywhere constitution.
Above deck, the saloon cabinhouse has a cored fiberglass coachroof over the aluminium structure. The hull carries 74 mm of insulation, supplemented by insulated flooring and double-glazed windows throughout the saloon. A watertight, double-glazed door, obstructable dorade boxes, and forced mechanical ventilation complete the envelope.
Rig, Performance, and Handling
The cutter rig carries about 980 square feet of upwind sail area. Gennaker options range from 980 to 1,720 square feet. All control lines run beneath the deck to the cockpit coamings, keeping the working areas clear.
Test sailors found the Exploration 45 easily driven, particularly off the wind. Raising the board reduces wetted surface, helping the boat along on broader points of sail. In a 20-knot chop, she was fully powered up at roughly a 40-degree apparent-wind angle and made better than 6 knots.
The wheel remains light and easy, with only a touch of weather helm in a strong breeze. In light air, it feels positive with little lee helm. The deep skeg adds directional stability, allowing the sails to remain untended for long stretches.
Her motion is remarkably smooth for a monohull and very comfortable in a confused sea. The trade-off is that windward performance suffers from the lack of weight low down, and she isn’t the most exciting boat to sail. One owner reported that the Exploration 45 is more closewinded than an Ovni 435. The lifting foil is a “foil-shaped centerboard” in the builder’s own description.
Cockpit and Accommodations
Reviewers found the cockpit layout excellent. The overhanging coachroof serves as a hard dodger and creates a sheltered outdoor watchkeeping position. A rigid cap over the helm station is inspired by IMOCA yachts. However, the raised roof blocks forward sightlines near the centerline.
Inside, the raised saloon is the dominant feature. It offers a 270-degree panoramic view, shared by the galley. The forward navigation desk sits behind the windshield and includes secondary autopilot and engine controls, allowing an active watch to be kept from inside.
The owner’s stateroom is forward, with an island double berth and an ensuite head. Two bunks line the passage. A larger port-side aft double lies opposite a cramped starboard aft cabin with two single berths. Depending on the layout, the boat has two or three cabins and sleeps five or six.
There is also a proper workshop for tools and spares. A seat aft of the saloon converts into a chaise longue. Despite these useful features, the interior as a whole feels somewhat cramped.
Heating and ventilation are excellent in every cabin. Radiators run from a central diesel boiler, and the galley has an opening hatch above the stove.
Equipment and Systems
The systems installations are first-rate. The engine space is easy to reach, and the centerboard trunk includes a useful inspection port.
Transfer pumps move fuel and water between the port and starboard tanks, allowing the crew to fine-tune the boat’s weight as supplies are consumed. The anchor chain leads aft from the bow through a sealed pipe to a windlass just forward of the mast, then drops into a watertight locker in the owner’s head.
Aventura IV illustrates the design’s self-sufficiency brief with a full solar array, a wind generator, and a water generator. The standard equipment list also names a watermaker, hydrogenerator, and generator.
Jefa steering is fitted, and a bow thruster is optional.
Known Issues
Reviewers isolated one notable handling issue: friction in some of the under-deck control-line runs. Important lines, particularly the main halyard and mainsheet, have a little too much friction in their routing.
Although the saloon windows are double-glazed, the hatches and hull-lights are not. That distinction is worth noting because of the potential for cold-weather condensation around those openings.
Verdict
The Exploration 45 is a purpose-built voyager. Its aluminium hull, twin watertight bulkheads, and retractable centerboard give it genuine high-latitude credibility without giving up the comforts of a deck-saloon home afloat.
It was conceived so that one watchkeeper could manage the boat while also caring for the crew. That intent is clear in the forward navigation station, sheltered cockpit, secondary controls, and ability to hold a course with the sails untended for long periods. It isn’t the liveliest boat to sail, and some interior and sightline compromises come with the protected deck-saloon arrangement, but its priorities are consistent and clear.
Pros
- Aluminium hull with bow and stern watertight bulkheads and a skeg-protected shaft
- Retractable centerboard provides 3 ft 5 in of shoal draft and 9 ft 2 in with the board down
- Panoramic deck saloon with a forward navigation station and secondary controls
- Smooth, easily driven motion, with a light helm and good downwind range
Cons
- Under-deck control-line routing adds friction to the main halyard and mainsheet
- The interior feels cramped, and the raised roof blocks forward sightlines near the centerline
- Hatches and hull-lights aren’t double-glazed, making them weaker points in cold conditions
