S/V Mirounga is a 1997 Prout 45 three/four berth owner’s Version catamaran for sale by owner. She was designed to be the ultimate ocean-cruising catamaran in comfort and safety. Designed by David Feltham and built from 1995 by Prout Catamarans on Canvey Island. She is solid fiberglass under the waterline, cored above the waterline, with Kevlar reinforcement. The original Prout Catamarans are renowned for their safety, load-carrying capabilities, reliability, ease of handling and comfort, and were designed for long-term liveaboard cruising and ocean passages.
Port Hull Mirounga has an interior layout based on the standard family version. The whole port hull is the owner’s stateroom with a berth in the aft cabin, vanity, drawers and various lockers, with large hanging lockers in the aft cabin and mid-ships. Her ensuite head includes a shower with full standing headroom. The mid-ship area also contains a top-loading fridge.
A full-size chart table is in the bridge-deck saloon. The saloon offers L shaped seating around a large table.
Looking forward of the saloon is a cabin with full-size double berth. Curtains cover the bulkhead cut-out. Access to this bunk is via steps in the forward starboard cabin.
Starboard Hull holds her galley which is midship and features a shelf unit on the inboard side for stowage of crockery, mugs, glassware, etc. Aft of the galley is the main guest cabin with hanging locker, drawers, vanity and ensuite shower and head. Moving forward is access to the bridgedeck berth.
Mirounga was owned by her original owner until 2021. She’d been well taken care of and was ready to go – the second owners (2021-2022) made a few improvements along the way to make her even better. They lived aboard very comfortably for a little over a year before returning back to land-life.
Family Layout with four double berths and two showers / WCs. Comfortable for two adult couples and four children or three adult couples with the fourth double bunk being used for storage. With just the two of us onboard, she’s been ridiculously spacious! Mirounga also has copious amounts of storage in both cupboards/drawers and lockers.
The upgrades made (see details below) have meant that you never have to worry about running out of power or water (no ‘boat showers’), and we can keep cool and comfortable. Compared to some newer catamarans, the Prout is solid, stable (less likely to roll on anchor) and very spacious feeling. Guests onboard have been over 6ft tall, with no headroom/bunk length issues. Mirounga is pleasure to own and we want to see her continue to be loved and enjoyed as a liveaboard.
