Technical Support: Kadey-Krogen Yachts, Stuart FL

When making extensive improvements and modifications to any vessel, it's helpful to have access to the original drawings and engineering specifications. In most cases that information is simply unavailable. However, in the case of Kadey-Krogen, Vice President of operations Tom Button proved to be an invaluable resource. Not only were drawings available, Tom's knowledge of this generation of boat and of all Krogen products was extraordinary and freely shared. Thanks to Tom and the Kadey-Krogen team, no guesswork was required.

Engine Room Soundproofing: Chris Brunt Engineering, Topanga CA

Mr. Brunt is an acoustical engineer specializing in Cabin Noise Reduction (soundproofing) programs for many the world’s largest private and corporate aircraft, such as the Boeing Business Jet (B737), B757, B767, and the Airbus A318, A319, A330 and A340.

Chris’ unrivaled engineering skills are backed up by his great “ears”, as evidenced by his parallel career in the recording industry, where he has engineered, mixed and/or produced albums for many top jazz and rock artists, as well as designed a number of concert halls, recording studios, and private listening rooms.

Chris engineered a unique and incredibly effective “room within a room” engine room soundproofing system for Stout, then oversaw its installation and the measurement of results.

Electrical System Design and Engineering: Arild Jensen, C.E.T. , Vancouver B.C.

The late lamented Mr. Jensen, an electrical and electronic engineer, was well-known in the trawler community for generosity with his expertise on the forums. He designed a number of inverters such as the original Heart, and famously quit Xantrex when they moved manufacturing to China and quality dropped.

Arild provided design services, specifications and engineering oversight on Stout’s electrical systems’ upgrade for greater efficiency, capability and ABYC compliance. The use of Victron Energy (Netherlands) inverter chargers, a Balmar alternator and regulator, Lifeline batteries, Blue Seas Systems components, oversized Ancor cables and many other products on this project was due to Arild’s influence and his tendency to cheerlead any propensity for overkill where safety and efficiency were concerned.

Hull Modifications and Improvements: Hull-Tech, Inc., San Diego CA

New Zealander David Biggwither and his team performed the “peel” and re-lamination of the hull with premium materials to prevent osmotic blistering, all fiberglass work for the installation of the stabilizers, bow thruster,  and through-hull fittings, and oversaw much of the yard work at Driscoll.

While Hull-Tech specializes in top-quality hull and fiberglass work, David is quite the shipwright, with experience and skill in a variety of areas. Consequently, they were also tasked with the fabrication and installation of the engine room parts storage (in a manner to further stiffen the hull), rebuilding the running gear, specification and installation of the Aquamet 22 shaft and Duramax shaft seal and a variety of other tasks. They do truly brilliant work at Hull-Tech.

Mast and Boom: Forespar Inc., Rancho Santa Margarita, CA

Forespar manufactures some of the finest custom aluminum masts in the industry. Having seen their custom masts with power booms on various Nordhavn models, they were approached for this project. They completely reworked the Krogen mast to incorporate a power tender-launching boom similar to the Nordhavn’s, as well as integrating into the custom spreaders the antenna mounts that I desired to provide upper support for the 21-foot high comm antennas. They also built the open array radar mount and made a number of suggestions which they incorporated into the final product, including specialized mounts for lighting, camera and instruments.

Joinery: D.L. Ott, Shipwright, whereabouts unknown

The exquisite teak joinery is one of the things that caused me to fall in love with Kadey-Krogen yachts of this era, as it is simply unavailable today.

The planned modifications to the interior of Stout included integrating extremely high-quality audio and video components, additional lighting, hydronic heat, stabilizers and a custom convertible cocktail/dining table.

Executing that vision while maintaining the integrity of the original Krogen design, making it look like Krogen built it that way originally was a real challenge. The solution came in the form of David L. Ott, a master shipwright and cabinetmaker.

From building custom jigs to exactly match the beautiful teak louvers used throughout the boat, to building wiring chases and valances involving complex compound curves which would accommodate and conceal speakers and lighting in prominent locations, David pulled it all off beautifully.

No less of a challenge was implementing the Chris Brunt Engineering design for what is in essence an isolation-mounted room within an engine room, while maintaining access to all components and tanks and further providing engineered mounting for a large quantity of new equipment.

David’s final compound-curve project was to built the custom propane locker beneath the starboard flybridge seating, in furtherance of ABYC compliance.

Getting to Know the Lehman: American Diesel Corp., Kilmarnock VA

Bob Smith founded this company in 1981 after leaving Lehman Power as the managing director of that company. Bob was instrumental in the design and sale of the Lehman Ford engines sold worldwide. His knowledge of each engine part and the boats into which they were installed has made ADC the leader in parts supply and support of the Lehman’s. Bob’s hands-on training course, where a Lehman is taken apart and re-assembled, was a wonderful way to become entirely confident in the engine and one’s ability to maintain and repair it.

Interior Design and Soft Goods: Foshay Interiors

Laurie Foshay Nada was regarded as one of the most visionary and well rounded designers in Southern California, designing both elite private residences and numerous model homes for large builders. It was due solely to a long-term friendship that Laurie agreed to take the small job of Stout’s interior. In many fields it turns out that the smallest job is the most work and the most difficult. Laurie endured endless testing of foam densities for various applications and a “client” far more particular than the owner of the largest of the orange county mansions that she was accustomed to designing. At the end the results spoke for themselves, and Laurie clearly could have qualified for sainthood.
