Sanctuary is a 1988, single engine, Taiwan-built Monk 36 Cabin Trawler. She is powered by a Cummins 4BT-3.9 diesel engine, a Borg-Warner Velvet Drive 71C transmission, a 2.57:1 reduction gear, and a 3-blade, 24″ x 20 pitch, left-hand rotating wheel. She cruises at 7.3 ~ 7.5 knots, or 8.4 ~ 8.6 StM/Hr, in still water. She makes 2.80 StM/gallon. She is fit with a hydraulically-operated stern thruster system, which is mounted aft, on the outside of the hull. The location of the thrusters make them easy to maintain, and avoids loss of space in the chain locker.
Her previous owners had obviously only used the boat for local, weekend outings. When we bought her, she was 16 years old, had three previous owners, and had 2000 hours on the engine. We bought her as a bare-bones platform, and fit her up as the cruising boat she is today. Considering the amount of re-fit she needed, I’m not sure we would do that again.
To cruise and live aboard, we faced significant immediate projects included fitting up a 7.5 KW genset (and all the electrical connections, transfer switching, fuel supply, cooling water, and exhaust plumbing for it), a windlass, chain rode, an anchor upgrade, upgrade of navigation electronics, and a lot of cosmetic work. In our first months aboard, we upgraded the AC and DC electrical systems to become ABYC-compliant, and installed all new hoses on thruhulls and the engine. As the seasons progressed, we refurbished all of the mast wiring (nav lights, anchor lights, deck lights), fit up a digital battery monitor, changed the OEM battery configuration to better utilize battery capacity, fit up a Galvanic Isolator and a 2KW inverter/charger. We installed 1000# of lead ballast in the stern. We’ve fit up other new equipment over the years, including a dual-channel AIS receiver, an Autopilot system, and a DC sub-panel for our flybridge instruments. We replaced the OEM salon heat pump, the OEM SS engine waterlock muffler, and the OEM fridge. So, a lot of work.
Although Jim has the skills to do all this work, if we had it all to do over, we would probably make a different choice. It took more time to complete the initial upgrade work than we had anticipated, and delayed our initial ability to cruise. We probably invested more money fitting up new equipment than we would have spent in buying a ready-to-cruise boat. That said, today, Sanctuary is all that we had hoped she would be, and we love her and our years of life aboard.
