Sailpages Buyer's Take

The Island Spirit 37 is a South African-built catamaran designed by Phil Southwell and constructed by Fortuna Catamarans between 1998 and 2005. With a displacement of 15212.0 lb and a beam of 22.08 ft, this model represents a specific era of production where build counts are not definitively recorded in the available data.

Best for:
This vessel suits coastal cruisers and those seeking a stable, wide-beamed platform for relaxed cruising, supported by common owner upgrades like watermakers and davits that indicate a focus on self-sufficiency and comfort.
Bluewater capability:
With a low capsize ratio of 3.57 and a displacement of 15212.0 lb, the hull form suggests reasonable offshore stability, though the lack of specific bluewater owner reports limits definitive assessment of its long-range capability.
Comparables:
Comparable boats from this era include other South African catamaran builders like Lagoon or Fountaine-Pajot models of similar beam and length, as they share the fractional sloop rig and similar displacement-to-length ratios.
