At Anchor, Mooring Or At The Dock

 The KK 54 is the perfect live-aboard home, whether at anchor, a mooring, or in the marina. The boat was thoughtfully laid out and modifications and additions, such as Flopper Stoppers, Hydraulic Drum Anchor Chain Windlass and Electric Windlass, Oversized Anchor, Deck Crane and Dinghy make life comfortable wherever one stays. Her long-range, fuel-efficient hull, water maker, and heating/cooling systems allowed the current owners to live on her for 7 years making memories from Miami to Maine. The STARLINK onboard network has proven a huge benefit whilst cruising and will be transferred on closing.

Sails And Rigging Systems And Use

As sailors at heart, we still love to have her sails up and pulling any time the wind is favorable.  The main sail and mizzen are easily managed from the deck or the upper helm. The jib and ‘A’ sail are handled on the foredeck.

 

The sails' purpose was originally designed as a range extender keeping Ursa Major at hull speed whilst reducing engine rpm, providing significant full savings and the plus of the joy of sailing. The Krogen 54 has crossed the Atlantic on her own bottom. See the account of the passage in the Media section.

Refitting And Updating

 

In late 2017 we took Ursa Major to Hinkley Yacht Centre in Thunderbolt GA to have the hull and spars sanded, faired, and repainted in Awlgrip paint. They did a great job of the hull and spars and she gets compliments wherever we go on her shiny hull.

 

In late 2018 we took Ursa Major to Stingray Point Boatworks in Deltaville VA, to have the decks, windows, doors and superstructure revamped, reworked, updated, and painted.  All deck fittings were removed, serviced and refitted or replaced after the painting was complete. 

 

All the windows were removed and new custom Diamond Seal units were installed along with two new doors for the Pilot House. This complemented with the new paint job, painted winches and crane, and new non-slip decks finished the major parts of the exterior. New fasteners were used to refit all the deck fittings etc.

The Pilot House chart tables, instrument panel, and electronics were all updated, and teak work was replaced and varnished leaving us with exactly how we wanted our Pilot House – simple, functional yet safety redundancy with an integrated system by Garmin throughout the boat.

​

Introducing Ursa Minor (Dinghy) And Crane

Ursa Major has a MarQipt Crane for tender launch and recovery. The crane has been fully overhauled, painted in Awlcraft, and re-rigged with Amsteel rope.

The hydraulic valves and hand-held controller have been replaced and updated.

The new dinghy is an Offshore Cruising Tender 330 Model.  It weighs in at 120# and with the new 2022 Honda 15 HP with electric start and tilt is around 260# all up.

 

This is by far the nicest dinghy we have owned; is spacious, dry, stable, fast and mothership-friendly with her all-around closed cell foam skirt. The dinghy is a head turner at the dock or the beach with its lightweight and wheel system allowing easy beaching.  The dinghy planes early and easily and is often used for other water sports. I have done some scuba diving from the dinghy and its stable nature makes entering the water and boarding easy using the custom boarding ladder.

 

Safety

 

Jim Krogen’s design and build make the boat virtually unsinkable due to the closed-cell foam construction. The original specification said it was unsinkable.  See the KK 54 Brochure for more about her construction.

​

The control of the boat can be done from the Fly Bridge consul or the Pilot House.

We designed and added a removable cargo net that can be deployed from the deck or the water in the unlikely event of a MOB situation. This along with two throw slings, two life rings, floating line, and a deployable 8’ boarding ladder adds confidence to any situation. 

 

In bad weather, everything can be securely operated from the Pilot House.  The boat also has Hydronic heating with demist capability for the Pilot House front-facing windows. Halyards are long enough to accommodate rescue from the water too as one would on a sailboat.

 

FireBoy engine management system added in 2021, which would shut down main engines, generator, and blowers in the event of a fire to optimize fire retardant Haylon Gas. FireBoy propane switch and leak detectors on Galley stove.

 

AIS, ERIB, and VHF radios on board as well as radar, foghorns, lights horns etc.

Fire equipment has been examined annually and updated as required. CO and smoke alarms are in each cabin or area.

​

Engines have their own dedicated raw water failure alarms and power is monitored through the Victron system described later. The AC power system has been audited by a professional ABYC electrician and complies with new standards and we have never had a power issue during our travels because of the boat.
