Introduction Construction Installation Systems Sea Trial
The Tunanator shows her 1970 vintage lines well. She's maintained her integrity for 30+ years and this was very evident when I cut 8" oval holes in the bottom of the boat for the new underwater exhaust. The pieces that I removed were laminated out of 3 layers of 3/4" marine plywood covered with a single layer of fiberglass cloth. The core was totally dry and seemingly brand new. I'm not sure that this type of quality wood construction is easy to find anymore.
I met the owner of the Tunanator, Randy Carpenter, about 3 years ago under an unusual set of circumstances. He had gotten himself into a predicament late on a Sunday afternoon while trying to take his boat through the Channel Islands Harbor to his home in Mandalay Bay..he needed to pass under a bridge. The tide was high this day and Randy, in a hurry to get home, decided that using a saw on his mast was the solution to arriving on time to his dinner date that evening. The following Monday, Randy showed up at my shop with the top five feet of his mast in back of his truck along with all the antennas dangling.

He mentioned that someone told him I could make most anything and showed me a drawing of what he'd like to have fabricated for his boat - - a hydraulically controlled lay-down mast capable of holding a variety of antennas, lights, and a satellite TV/communications dome. To make a long story short, 2 months and $7,000.00 later we became pretty good friends.

Over the next year or so, I learned quite a bit about his 60 ft Elliot that was built in Southern California in 1970. It was powered with twin Cummins 903's (450hp V8's) w/ remote V-drive power-trains. This boat was in pristine condition and, since new, was always kept that way. There had been many upgrades over the years but a modern power-train wasn't one of them. Randy loved the boat but was not happy with the 9-10 knot cruise. We started discussing what type of performance we could get with some modern higher hp diesels and how we could work around the existing engine room dimensions. Although the engine room was clean, it was quite difficult to work in due to the layout of the present engines, generators, etc. The 903's were quite large for their power and the boat had two large 15kW Northern Light generators between the main engines making for difficult maintenance for anyone but the skinniest of people.

After much research into the existing performance, propellers, etc. on his boat, I determined that the best choice would be a set of Cummins QSM's (635hp), a pair of remote-mounted Twin Disc 5114RV remote V-drives, and a pair of 21kW Onan generators. After a thorough redesign of the engine room layout, we were able to accomplish this repower and make the engine room bright, spacious, and much simpler to maintain.
