1988 Kelsall Manannan Custom

1988 78ft Bluewater Catamaran for Sale

Extensively Refit | Offshore Performance | Charter-Ready | Private Liveaboard| Global Cruiser 

Location: Ponce, Puerto Rico, USA

Overview

This 1988 78ft custom bluewater catamaran for sale in Puerto Rico is a proven offshore cruising yacht, extensively refit and ideal for Caribbean charter operations or luxury liveaboard sailing. Designed by the legendary multihull innovator Derek Kelsall and built on the Isle of Man using advanced foam-core composite construction.

Engineered for long-range ocean passage-making, liveaboard comfort, and charter operations, she delivers a rare combination of performance, durability, and autonomy. Her offshore pedigree includes an impressive finish in the 1990 Atlantic Rally for Cruisers (ARC), where she outpaced competitors by nearly two days.

Owned and meticulously upgraded and maintained since 2008 by two extremely knowledgeable USCG Master-level captains, this vessel has undergone extensive exterior and interior refits (2023–2026), making her a true turnkey bluewater cruising yacht or income-producing charter vessel.

Why “Cat’s Meow” Stands Out

• Extensive refit (2023–2026) – mechanical, electrical, cosmetic, and rigging – makes this a turnkey bluewater catamaran for sale
• Proven transatlantic and offshore cruising history
• 5-cabin / 5-head layout ideal for charter or private use
• Massive fuel (1,600 gal) and water (800 gal) capacity for long-range cruising
• Dual generators + redundant systems for reliability offshore
• Professionally maintained by licensed captains

If you are in the market for a large catamaran for sale under $1M, offering capabilities comparable to significantly newer vessels at a fraction of replacement cost, Cat’s Meow represents an incredible value opportunity.

Ideal For Buyers Searching

• Luxury liveaboard sailing catamaran
• Crewed charter yacht business opportunity Bahamas / Virgin Islands
• Expedition sailing yacht for global cruising
• Large bluewater cruising catamaran for family with room for guests and crew
• Turnkey charter catamaran in the Caribbean

Investment & Charter Potential

With her 5-cabin, galley-down layout, system redundancy, and proven reliability, “Cat’s Meow” is well-suited for:

• Crewed yacht charter operations (Caribbean / Bahamas / Florida Keys)
• Boutique charter business, liveaboard diving, or eco-tourism platform
• Owner-operator hybrid charter model

A compelling opportunity for buyers seeking a yacht that can generate revenue while supporting a luxury cruising lifestyle.

Cruising History & Pedigree

Cruised extensively from Nova Scotia to Grenada, demonstrating capability across cold-water, offshore, and tropical cruising environments, as well as completing a transatlantic crossing.
