Scott Fratcher - Marine Engineer/Captain

Box 147373, Ponsonby Auckland, New Zealand

I have extensive experience troubleshooting, designing, engineering and installing systems on the small sailing yacht and over 100,000 miles in the midrange (30-50 meter) vessels. My wife and I sailed our steel gaff ketch to New Zealand from Ecuador in 2004.

I have a strong reputation in the field and have worked mainly through word of mouth. Twenty years on the ocean has taught what works.

Marine qualifications and experience

RYA Yachtmaster-200 Ton Sail/Power/Ocean/Commercial

Marine Engineer
MEC3 (Similar to Y-3) STCW iii/3
200,000 sea miles over the last 20 years, mostly serving as Chief Engineer on vessels in the 50ft-110ft range.

Electrical Diagnostician
I have been employed by Yanmar Engineering Services in New Zealand where I was a Senior Technician.  I routinely worked remotely on Kohler/Yanmar Generators. 
2005-Completed and passed (with a 99.5%) the training for a New Zealand ESTA1 Electrician at Matuhrangi Technical Institute. 

I bring to the job many specialty diagnostic tools that make me very efficient. These tools include a Fluke 87, a Fluke 36 AC/DC clamp amp, a hand held laser temp, and an MFJ 257B Antenna Analyzer. I know most high output alternators and regulators by heart including the Balmar, Ample Power, Powerline, Link 10/E-Meter, BEP and the Safe-T-Plus systems. I can typically find most long-term installation faults in just minutes. I have a very high success rate increasing the output of installations to the manufacturers designed specifications. 

Dual Alternator/PTO System
I have designed, built and installed over 100 dual alternator systems. I was involved in the pioneering of this industry in the mid 1980's. I am currently designing PTO systems for Yanmar New Zealand and Yachtwork where we produce boxed kits sold around the world. 

Diesel Engine Change
I designed a "Ten Day Diesel Engine Change" for the small yacht. (My personal record is 3 days, and my longest time to sea trial is eight days). This system is a fast and efficient method to remove the old engine, rebuild the engine rails, and then install the new engine. 

Electrical Panel Builder
I have extensive experience building and “Cleaning Up” electrical panels. I use a heat shrink labeling system so others can follow my work easily and efficiently.

I have written four books in the marine field, (see and have a monthly column in Tradeaboat of New Zealand. My works have been carried in The Titian, Discovery Turbo, Pacific Yachting, and many web sites.
