Eco bottom paint testing, back to copper and Irgarol

I did hire a diver to clean Gizmo’s bottom last September, but he said he found very little hard growth. So it seems fair to say that the water-based copper-free Pettit Hydrocoat Eco did well in that department…But I’m sorry to report that even the extra Zinc Omadine biocide did not prevent the brown slime from growing fairly thick at Gizmo’s waterline just a month or so after launch…

Ode to hydronic boat heating, and Sure Marine Service

Maretron_DSM410_showing_boiler_in_action_cPanbo.jpg

It seems appropiate to kick off 2018 with a discussion of heating technology, specifically the diesel-fired hydronic system I installed on Gizmo last year. It was a significant purchase and a major install, but the 66 degree pilothouse temperature seen above certainly made my early December ICW trip a lot more pleasant. I’ll explain why I chose hydronic, detail how the system went together, and profusely praise Sure Marine Service, a marine heating equipment distributor par excellence…

IBEX Winners: Lumitec PLI and Power-Pole Vision

IBEX_winner_Lumitec_Power_Line_Instructions_cPanbo.jpgWhat’s amazing and IBEX award worthy about the Lumitec demo board above is that while all those light fixtures are only connected to the same simple two-wire 12v power circuit, each can be switched, dimmed, strobed, color-changed and more, individually or as virtual groups. Lumitec calls the protocol Power Line Instructions (PLI), and, as innovative as it is, it had to share top honors in the electronics category with another new-protocol-based product, and we judges wished we could give out more awards. The boats of the future may be emerging from the fog…

Simarine Pico: Good ideas in battery monitoring & more

Simarine_Pico+_battery_monitoring_sleep_screen_aPanbo.jpgWhile this boat’s main battery bank is at 73% state of charge (SOC) — a near minimum for the long term health of many battery types — the lightning icon and blue up-arrow indicate that the charging sources exceed the loads and, in fact, a 100% SOC is expected in 9.5 hours at current rates. The 3.5-inch touchscreen is also displaying time and barometric pressure with trend, and this is just the sleep screen of what seems to be a very modern family of reasonable-cost monitoring products. Say hello to Simarine…

Ebikes for boats, learning from a Sondors

Sondors_electric_bike_profile_aPanbo.jpg

Folding bikes seem great for cruising boats. You can extend your sightseeing, fetch supplies, or simply get some rolling excercise. But I’ve wondered if a compactable electric bike could be even better and more fun. While that manly beast above is certainly unfit for stowing on even a mid-sized trawler, it’s led me to love the ebike concept and taught me what a good one may look like for my cruising situation…

New: Lars Thrane sensors, B&G Triton2, and Maine Cat 38

Lars_Thrane_LT-1000_NRU_and_LT-500_AHRS_aPanbo.jpgToday I’ve got a smorgasbord of new gear to share, starting with a trio of serious multi-sensors from Lars Thrane A/S in Denmark. The company first came to my attention when they inquired about advertising — thanks, LT — but a little research revealed why their products may well appeal to Panbo readers. The LT-500 AHRS in the foreground is an 11-sensor Heading, Roll, Pitch, Air Pressure and Temperature device; the LT-300 GNSS not shown is a 72-channel GPS/GLONASS/BeiDou receiver; and the LT-1000 Navigation Reference Unit (NRU) shown installed essentially combines the two. Common to all of the current Lars Thrane products is promised high precision, reasonable pricing, simultaneous NMEA 0183 and 2000 output, and an impressive attention to the real boat details involved in installation, calibration, and future proofing…

Summer fun: Camden, Panbots & Gizmo

yachts_RH3_and_RH4_special_opps_style_lr_cPanbo.jpgHave we reached the era when “special ops” makes sense as a superyacht style? I joke, but RH3 would be pretty imposing even if it weren’t cruising Maine in company with the all-black, dual jet drive, 40-foot-plus RH4. Given the two other substantial black tenders on the boat deck — and lord knows what’s in the hidden arms lockers (ok, I’m fantasizing, but armament is a seriously untold big yacht story) — this team seems ready to fend off a serious bad guy attack or invade a small island nation…

Gizmo’s new Firefly battery bank, working out the details

Gizmo_Firefly_Carbon_Foam_AGM_battery_bank_cPanbo.jpg

When I wrote about replacing Gizmo’s house battery bank, I was already inclined to try Firefly Oasis AGMs, and my enthusiasm has only grown. It certainly helped to have RC Collins and Nigel Calder testify further in that entry’s comments about how deeply they’ve “abused” these batteries in ways that boaters like me tend to do. I’m excited about gaining significantly more usable, easy-to-replace power capacity, and the Firefly’s smart, colorful exterior design is a nice bonus. But the switch from two conventional 8D AGMs to a four Firefly bank naturally led me to rethink Gizmo’s battery storage, cabling, charging, and monitoring systems. The job isn’t done yet, and maybe discussion of the details with you all will change the design again…

SL Fridge Optimizer, smart new product from a new company

Arvid n Annika of_Stainless_Lobster cPanbo.jpgHere are Arvid and Annika Elias as they showed me a prototype of their very first marine electronics product in the press room of last fall’s Ft. Lauderdale Boat Show. I was quite impressed and am now pleased to report that the Stainless Lobster Fridge Optimizer is official and shipping. If you’d like better monitoring and control of your boat’s electric refrigeration system, and/or automated defrosting (fridge only, not freezer), and/or improved battery time at anchor, read on…

Electric Boats: Steyr HDS+, LTS Marine, Torqeedo, windmills & more

eCraftYachts_20_WOT_cPanbo.jpgThe first U.S. Electric and Hybrid Marine Expo was wonderfully educational, though I hardly knew any of the companies involved and could only understand a fraction of some seminars. On the other hand, I met a familiar fellow enthusiast before I even left the Lauderdale airport. Rufus Van Gruisen is the esteemed owner/operator of Cay Electronics, and it turns out he’s done more than just dream about quiet, efficient electric pleasure craft. That’s him in the orange cap above, showing Newport the first eCraft Yachts 20 that he helped his son to build. It looks like an excellent design to me — more detail on Facebook and in Great Lakes Scuttlebutt — and I’d presume a well-engineered power, control, and nav electronics installation.
