As part of my midseason checkup, I reviewed the electronic devices and apps I use. Seems a bunch has happened that I had not really taken into account. Some navigation apps work better than others, and some no longer work at all. Companies consolidate and merge products and technologies in this shifting landscape, much like it did when paper charts were replaced with various formats and digital standards.
The question of single engine versus twin engines has been beaten to death many times over, in my opinion. It really doesn’t matter which you choose, as a single engine with a bow thruster can perform as well as a boat with twin engines. But given how the marketplace has evolved, many buyers are looking at older trawlers, and the age factor somewhat changes the discussion.
Do you know about Sea Tow's Automated Radio Check service? It should be part of your normal operations routine, and used often to ensure your radios and antennas are working as well as you hope they are.
Far better than the traditional radio check of throwing out a call and hoping someone will respond. And let's leave "10-4, Good Buddy" ashore, please.
The value of an engine survey can't be overstressed when looking for your ideal cruising boat. A separate effort from a general boat survey, an experienced mechanic's skill at judging the overall health of a boat's engine(s) and generator gives you the ability to decide if the boat is right for you, or if you should keep looking. More so than any other element of a cruising motorboat or trawler, the engine room is the most important space on the boat.
Rather than guess what speed you should run your boat, it is important to develop real-world numbers of the speed and burn consumption your boat reaches at various engine speeds in open water. Depending on how your boat is equipped and loaded, and the propeller(s) you have, it is a straightforward process to develop a speed/fuel burn performance curve that will identify the sweet spot for running your boat at cruising speed.
Along the way of determining this ideal speed envelope, you will also get an sixth sense of when the hull and engine is in harmony as she glides through the water with maximum efficiency and reasonable fuel burn. This is a satisfying project every boat owner should create for his or her boat.
