At the Ft. Lauderdale International Boats Show, I had the chance to test out the performance of Seakeeper’s Ride stabilization systems aboard a 35 foot performance cruiser capable of hitting 40 knots.  We took the boat to government cut and ran it in and out through a nasty washing-machine seaway. The stabilizers are mounted on the stern and make trim adjustments in micro seconds. The effect was dramatic. With the Ride system engaged, the boat leveled off, did not roll or pitch and did not yaw as it moved through the mixed up sea. Turned off,  the boat’s motion was…

YANMAR Marine International has announced the launch of its VC30 at Metstrade, a third-generation Vessel Control System, with advanced design and functionality, a newly designed precision-engineered joystickand easy installation.  YANMAR’s most advanced control system to date, the VC30 is designed to simplify throttle control and docking in one integrated system, whilst making it easier to view data and create a seamless dashboard.  The full system is enhanced by a high-quality display and modern design, including alarger, 4.3” 1000cd optically bonded screen, to reduce reflection and improve readability, with NMEA2000 output. The display unit has an auto dimming function for dark…

On September 10, 1982, three passengers aboard a light aircraft crashed into the sea off the Canadian Maritimes. They were able to deploy their life raft and they had with them the earliest version an Emergency Position Indicating Beacon (EPIRB). They switched it on and set in motion the very first COSPAS-SARSAT rescue. They were found and rescued in a matter of hours instead of the days such search and rescue missions took before the satellite rescue system was in place. Since then, more than 50,000 people have been saved from a watery end by EPIRB technology. For those of…

Whether you are looking to add radar to your boat or it’s just time to replace an old and out of date unit, there are a lot of considerations that should go into the decision-making process. To start, you need to be certain that a new or replacement radar is compatible with your existing marine electronics. In other words, will the radar display appear on your multifunction display so you can overlay the images onto the digital chart.  For simplicity’s sake, it makes sense to stick with one brand for all electronics. The size of radar you choose depends on…

Volvo Penta introduced Joystick steering two decades ago and has continued to pioneer ways to use the combination of engines,  thrusters and GPS to help skippers maneuver their boats more easily and precisely. I was involved in the early demonstrations of the Volvo Dynamic Positioning technology  back then and was amazed at how well even the prototype held a boat in position and allowed the skipper to turn a boat inside its own length. Last fall at the Ft. Lauderdale show, I got to test the latest Volvo Joystick iteration with the new Assisted Docking Function that allows you to…

At last September’s Cannes Festival of Yachting in the South of France, I attended Beneteau’s annual press event and was introduced to the innovative electric Island Cruising Concept Yacht.  Always an innovator, Beneteau had a vision of boating and chartering in the future. Now, Dream Yacht Charters is offering that future in the BVI. Their fleet of sail and power boats now includes the boxy-looking electric hybrid power boats that are like floating beach houses with accommodations for a normal chart6er party The Island Cruising Concept is all about indoor-outdoor living and practical sustainability. The idea is to be close…

In the last few years as I’ve been making offshore trips as crew for my friends, whether back and forth to the Caribbean from New England or across the Atlantic, it seems that a lot of the crew  aboard show up with their own hand-held GPSs and an InReach or a satphone. This is a “just-in-case” level of preparation by sailors who have in fact been on boats that were hit by lightning or suffered a battery bank collapse that meant built-in marine electronics were no longer working or reliable. Garmin has long been a leader in hand-held GPSs and…

Volvo Penta has been working on electric propulsion and hybrid diesel-electric systems for a decades. The diesel-electric system coupkled to IPS drives is now available for commercial and recreational use and provides an elegant and proven technology that will allow boats to run silent and carbon free. The electric motor in the system fits between the main engine and the IPS pod and is engaged with a clutch. The motors run off a bank of lithium-ion batteries that can be sized for each boat’s specific tasks and requirements. “A hybrid provides a flexible solution, one that maintains the high efficiency…

Most of the modern fast cruisers that run at planing speeds have trim tabs that are adjusted manually to level the boat off and make it run more comfortably and efficiently. Adjusting trim tabs takes practice and skill and affects trim slowly, not dynamically. Swedish inventor Niclas Olofsson, who has a PhD in hydrodynamics had a better idea. In 1994, while on a business trip to Fremantle, Australia, the boat builder he was calling on had a problem. The Chinese company that had ordered several small fast ferry boats had rejected the products because the ferries could not reach the…

Of all the natural phenomena that we run into out on the water, lightning may be the most worrisome. A direct strike can blow a thru-hull right off the boat creating a gaping hole, it can fry your electrical panel and battery bank and it can start a fire. Even near misses can create a mess inside marine electronics and the autopilot, or in the alternator and starter motor on your engine, or it can blow up an inverter-charger. Lightning works in mysterious ways so you can never predict where it will go and what damage it can do. That…
