Current Status – May 10, 2022

In March of 2020 we scheduled a haul out to upgrade our bottom job to Coppercoat Anti-Fouling. Just before the haul, while doing regular maintenance to our diesel engine we discovered the heat exchanger was completely shot and would require significant custom machine work to replace. This turned the bottom job into a repower which eventually became a refit.

It was a harrowing two year job made miserable by a terrible contractor and some businesses with predatory practices. We persevered and redid much of the faulty work ourselves, reaching so much higher than we initially hoped that what we have been left with can only be described as our dream yacht. In the last two years we:

  • Upgraded our anti-fouling to CopperCoat, which required grinding down beyond the barrier coat to apply
  • Added a stainless arch/pushpit now carrying 900 watts of solar
  • Added a 7.5 kW diesel generator
  • Removed and replaced our diesel engine with a 20 kW inboard electric motor
  • Replaced and repaired two thru hulls
  • Upgraded from 1.8 kW hours of lead acid batteries to 24 kW hours of Battle Born LiFePO4 lithium batteries
  • Added inspection ports and a fuel level sender to the diesel tank
  • Replaced propane stove with induction cooktop and electric convection oven built into a custom gimbal (designed by Nora)
  • Replaced the dorade/cowls with low profile deck vents
  • Replaced dodger fabric and windows
  • Installed a Blue Sea breaker panel with many other additions and upgrades in order to have a ABYC compliant system running both 48v and 12v
  • Installed a 5 kW 48v Victron Quattro inverter/charger

Due to all of this work keeping Ayala out of commission, and COVID keeping us off of other boats, we spent less than eight hours underway and traveled fewer than ten nautical miles between May 2020 and March 2022. Since March 10th 2022 we have:

  • Sailed from Alameda to Santa Cruz (85nm), during which we became fouled on a crab pot requiring a tow
  • Limped from Santa Cruz to Moss Landing (15nm) for haul and repair
  • Sailed from Moss Landing to Monterey (15nm) Where we anchored for four nights
  • Sailed from Monterey to Morro Bay (100 nm) Where we have been anchored for the last three nights

    Very nice project blogs. Wondering if your Nanni Marine engine went bad or you just decided to Re power with electric? I just purchased a 1986 Fairweather mariner 39 named Legacy. Might be interested in purchasing the Nanni Marine engine for parts. Please email me at

      Hi Robert, the engine was still working and I already sold it it to a local mechanic. I can look him up for you if you’re interested. I do still have lots of parts. Fuel/oil filters, zincs, extractor, exhaust components, etc that I’d be happy to sell for cheap. I’ll email you this week.

    Very nice detail on your projects. Just wondering if your Nanni marine motor went bad or you just decided to repower with the electric motor. I just purchased 1986 Fairweather Mariner 39 named Legacy. If your Motor is the same as mine I might be interested in purchasing replacement parts off it. I can be contacted at Looking forward to your repower adventure.

    My wife and I own a 1988 Fair Weather Mariner in the Santa Cruz Harbor. I’m very interested in your project to replace the diesel with an electric motor. Curious to know if you’ve yet selected a vendor for the motor ? Also, I have found that steering this vessel in reverse is difficult. I saw one past listing that showed a bow thruster installed. Robert Perry once responded on my facebook post and suggested a different prop. Any thoughts ? Thank you for sharing your story. It’s great to find another fan of this design.

      The repower is underway! It’s seriously delayed but should be done soon. Once we are in the water with the bills payed I’ll do a detailed review of everything from handling to installation process.
