At first glance, the SFK 275EX looks like many other 275-300 amp hour internal BMS lithium iron phosphate batteries. With Bluetooth communications, heating, long cycle life, and a good warranty it seems to compete well with other batteries. But, closer inspection reveals a battery with features above and beyond anything I’ve seen in similar form-factor and priced batteries. Not only that, it comes with a thorough and readable manual.
A lot has changed since early 2020 when I took delivery of my first, outboard powered, small test boat. Since then, the world experienced a global pandemic, Hurricane Ian devastated Fort Myers and surrounding areas, and we lost Have Another Day. Also, though less dramatic, I found my testing shifted towards the small boat and away from testing on a 57-footer. At the same time, after four years of installing equipment on her, Panbo(at) was beginning to look like the proverbial five pound bag stuffed with ten (or more) pounds of… stuff. So, I did the only logical thing and bought a bigger bag!

I have big things planned for upcoming battery tests. I’m working to evolve my testing of LiFePO4 batteries to match their evolution. Battery capacities are increasing, physical size is decreasing, prices are dropping rapidly, and acceptance is increasing. New options hit the market regularly and keeping up with the pace of change can be challenging. In the coming months, I will review quite a few batteries in different positions in the market and try to help readers decide which price point and battery is right for them.
Yes, Panbo friends, the time has come. Gizmo is officially on the market as of today, though thankfully not due to health issues, financial distress, or any other problems. I simply decided last fall...
Products developed by active cruisers grab my attention. In my experience, products created onboard solve needs and fix issues directly experienced by the creator. Pitufino is no exception. There is no shortage of NMEA 2000 to WiFi gateways in the marketplace. There are also quite a few NMEA 0183 gateways. But few of them are nearly as ambitious, flexible, or offer as many features as the Pitufino gateway.
As part of a well-engineered system, lithium batteries can replace generators and make life on a boat seamless with or without shore power. But they aren’t perfect. The battery industry continues to research improvements and alternative chemistries.
It’s now been four years since I installed Dometic’s all electric steering system (AES) on Panbo(at). When I wrote my initial review of the system, I bragged that after sixty hours on the boat the system worked perfectly and without incident. Allow me to add a zero to my brag. After six hundred trouble free hours I’m back with an update on the system, a new auto pilot, and information on additional all electric systems for more boat types.
We’ve been hearing about Starlink’s Mini terminal for a long time now. Recently, hints from regulatory filings, new documents on their website, preparation for the new terminal in the app, and even a Tweet from Elon Musk made it seem the introduction was imminent. This week, Starlink made links on the website live and started sending emails to some long time subscribers offering an opportunity to purchase the new terminal. Now we have the opportunity to see if the Mini answers some of boater’s gripes with the current hardware.
Wind sensors serve multiple purposes on a boat. For a sailor, they provide critical information to best harness the wind. For a power boater, they provide insight into conditions and a potential preview of close quarters manuevering. Regardless of the application, a simple, reliable, accurate, and easy to use wind instrument is something many boaters value. Does the Calypos Ultrasonic NMEA 2000 Wind Sensor deliver? Let’s take a look.
