Design and Construction
The hull and deck are hand laid and vacuum bagged, using premium marine-grade gelcoat, vinylester skins, a PVC closed-cell foam core described as unsinkable, and carbon reinforcements. This foam-core sandwich construction runs through both the hull and deck.
Unfolded, the trimaran has a beam of 14 feet 6 inches. It folds to less than 7 feet wide for road transport. Owners report that each beam-and-float assembly weighs only about 100 pounds and that two people can fold or unfold the boat easily. They report taking no more than 15 minutes to go from the parking lot to the water.
An on-the-water folding system comes as part of the standard package, along with forward and aft mast supports and a galvanized cradle with wheels and hull supports.
Rig, Controls, and Handling
The standard fractional-sloop sail plan includes an aluminum rig and a 2:1 main halyard. The 176-square-foot boomless mainsail has a single reef point, while the self-tacking jib uses a 2:1 sheet and a Harken headsail furler.
The Ronstan control-hardware package includes:
- A Cunningham system
- A traveler track with a single-line control car
- A 6:1 mainsheet
- Rotator-control tackle
- Synthetic cap shrouds
The boat has a composite daggerboard and dagger rudder, plus an aluminum rudder case, tiller handle, and tiller extension. A sail-area-to-displacement ratio of 51.75 and a capsize ratio of 6.59 place it among lively, light-displacement multihulls rather than ballast-dependent monohulls.
Accommodation
Below the lockable, watertight companionway hatch, the SeaRail 19 provides V-shaped storage or a single berth. The interior is minimal by design. This is a 19-foot trailerable trimaran intended for daysailing, resort use, or camper-style overnighting rather than cruising accommodation.
The watertight hatch is standard, reflecting the emphasis on keeping the central hull sealed and manageable when the floats are folded or the boat is resting on its cradle.
Trailering and Ownership
The ownership experience centers on the trailerable package. A mast-raising system, forward and aft mast supports, and the folding system allow a two-person crew to move quickly from highway to shoreline.
The standard galvanized cradle includes wheels, axles, and hull supports. Together with the lightweight beam-and-float modules, it makes the folded boat practical to handle. Spinnaker and asymmetric-spinnaker options extend its downwind sail choices beyond the 278-square-foot spinnaker area listed in the standard sail plan.
Known Issue
One documented concern came from the U.S. distributor, described as a multihull veteran. After inspecting the test boat, he appeared concerned and suggested that it not be tested because of a reported issue with the leeward float.
The Verdict
The SeaRail 19 is a thoughtfully engineered pocket trimaran that trades accommodation for portability and a genuinely low towing weight. Its Irens-influenced hull and foam-core construction provide a package described as unsinkable and easy to fold. A self-tacking jib and boomless main also help keep short-handed sailing straightforward.
The one flagged caution is the distributor’s reported concern about the leeward float on the test boat. A buyer should weigh that against the boat’s otherwise clean construction summary.
Pros
- Just under 700 pounds fully laden and a 1,100-pound towing weight
- Folds to less than 7 feet wide
- Two-person setup reported to take no more than 15 minutes
- Foam-core construction described as unsinkable, with carbon reinforcement
- Self-tacking jib, boomless main, and furler supplied as standard
Cons
- Minimal accommodation, with only a single V-berth
- Distributor reported a leeward-float issue on the test boat
