Owner Experience Review
Owners gravitating to the Long Island 78 PowerfromJFAtend to pursue genuine bluewater itineraries. The first delivered hull, “4Ever,” set out on a Mediterranean → West Indies → Pacific program following its February 2021 handover, reflecting the boat’s intended mission. With a stated transatlantic range of roughly 3,200–3,400 nm at 8 knots, the design aligns with owner-operated family cruising rather than a volume charter profile, and the series has been built in semi-custom, limited numbers.
On the water, sea-trial commentary describes a displacement powercat tuned for fuel economy and long-range seakeeping. In practice, owners and crews work within a sensible envelope: around 12 knots for everyday cruising, with press-reported peaks of 15–18 knots at light or half load. Natural stability at anchor and substantial deck volumes keep life aboard steady and comfortable in typical conditions, while the enclosed flybridge wheelhouse—set up as both a navigation and relaxation space—supports good ergonomics on extended passages.
Day-to-day living benefits from unusually generous spaces for a 78-foot multihull: an oversized aft cockpit, expansive foredeck lounge with an integrated seawater pool, and a light-filled interior with extensive glazing. A roughly 20 m² owner suite occupies the port hull alongside four guest cabins, giving capacity for eight guests plus two crew. Construction pairs aluminum hulls with a composite deck/superstructure, and typical propulsion is twin 500 hp Cummins diesels with standard service intervals; no recurring engine-failure patterns have surfaced in public searches, though long-term owner-maintenance reporting remains limited due to the small fleet.
Pros and Cons
- Stated 3,200–3,400 nm range at 8 knots and displacement powercat efficiency support genuine ocean passages.
- Natural stability and expansive deck spaces, including a foredeck lounge and seawater pool, enhance comfort at anchor and underway.
- Enclosed flybridge wheelhouse and light-filled interior suit owner-operated, long-distance cruising.
- Top speed reported at 15–18 knots is modest for buyers prioritizing fast transits.
- Limited number of semi-custom hulls means fewer peer references and market data than volume charter models.
- Public, long-term maintenance feedback is scarce despite generally standard diesel service expectations.
