Catamaran characteristics

Wide 21-foot-5-inch beam, twin mini-keels, twin rudders, twin diesels and a shallow 3-foot-9-inch draft. Three-cabin owners' and four-cabin charter-style arrangements. Bridgedeck clearance is described positively in an owner account, but no reliable numeric measurement is available, so none is displayed.

What owners say

• A 15,500-mile owner praises the accommodation and relatively high bridgedeck clearance, while reporting cracks around aft lazarette hatches. Source: Cruisers Forum: owner 15,500-mile review
• The same owner notes the awkward genoa furling arrangement on early boats and wiring that can be difficult to trace. Source: Cruisers Forum: owner 15,500-mile review
