Headsets – The Next Generation…

Jeff Seigel, founder of ActiveCaptain, writes…

For years, we've talked about the advantages of cruising couples using headsets for communications. There is no substitute. While hand signals may work in many conditions, we've found good communications is most needed when both hands are busy. And nothing compares to the ability to calmly and reliably talk between crew members while docking, anchoring, and during other maneuvers. In stressful situations, great communications removes much of the stress.

We bought our first headsets, the original toy models, in 2003. They became so important, we bought a second set in case there were problems.

They used the AM radio band and eventually started to pick up interference with the new electronics we were putting onboard.

About 5 years ago, a new generation appeared, characterized by the Eartec Simultalk 24G Multi-Station Wireless System. These used more professional audio equipment and radio bands to deliver a better solution. When we delivered Red Head from New York to Deltaville, those Eartec's were the first things we put in the pilothouse.

Five years in consumer electronics is many lifetimes. And today there is another, newer generation of headsets for boating. The two new models available are the Sena SPH10 and the Eartec UltraLITE. 3 months ago we were offered a set of each model for evaluation. We had one rule – if we evaluated them, everyone agreed we would release our honest findings in writing.

Both models use Bluetooth which means they can also connect to phones and other devices. We never used them for that – we only used them for docking, anchoring, and general communications (running wires, etc).

Bluetooth requires a pairing process to connect the devices together.

This provides a level of security so no one can overhear your communications. For both products, we found the pairing process to be annoying. The combination of pressing, holding, tapping, and standing by seems ridiculous. The instructions were not great for either product. We found the best way to get them to pair was to find YouTube videos and watch the procedure carefully.

Once they are paired, they remember their connection making real use much easier. Again, if you have procedural problems, look to YouTube for help.

So what did we find? We used both sets for all operations in different weather conditions. They are surprisingly similar and we can say that either model will do a great job. This new generation doesn't require a pack – everything is in the headset itself. That makes it a lot nicer than the previous generation. We do have our favorite and we'll explain it through a list of plusses and minuses for each product:

Sena SPH10:

+ They are small and comfortable although comfort is a personal thing A
+ USB cable charges each headset They have longer talk time
– It is difficult to talk in heavy wind conditions
– They are more expensive (especially this week)

Eartec UltraLITE:

+ They work amazingly well in heavy wind
– They block more outside sound on one ear – don't get the two ear model
– Batteries have to be removed for charging
+ A single battery charger charges the batteries for both headsets

Either device will work well and both are excellent for docking and undocking situations. But the Eartec's were significantly better when deploying and retrieving the anchor in the wind. And for whatever reason, we seem to frequently anchor in windy conditions. To make the comparison fair, during the anchoring tests in the wind, we switched headsets back and forth. Perhaps the Sena's need a windscreen or some type of mic that is less sensitive to wind. But there is a difference and for us, we're sticking with the Eartec's.

If you're a couple in a cruising boat and still believe that hand signals are all you need, borrow a set of headsets from someone and give it a try. Once you do, you'll never want to give them up.

Offbeat Charters from SuperYachtWorld

This is another great Google Map from Louise Busby..and in her own words “An increasing number of superyacht owners and charter operators are relocating their vessels to far-flung corners of the globe to entice the growing band of charter guests tired of cruising round the same old watering holes. We’ve searched the planet for the pick of these yachts and the experiences they offer, from sun bathing with iguanas in the Galapagos to snorkelling with elephants off those gems of the Indian Ocean. “….Great job Louise !

..although sailors and power boaters dont always get along:-) – I have to take my hat off to Louise who is web editor of the Broom Users Club and who has also the author of Inland Waterways of the Netherlands.

Rocna Anchors New Knowledgebase

Rocna KnowledgebaseRocna Anchors has released a comprehensive online collection of information on the topic of anchors, anchoring accessories, and the science of anchoring.

The Rocna Knowledge Base is a comprehensive, indexed and searchable digital encyclopedia covering anchors and anchoring.

The new website includes a section specific to anchors, including a collection of Rocna installation case studies, and guidelines for designing and building the ideal bow roller. Analyses of independent testing, explanations of anchor classification/certification, advice on sizing anchors and much more is also available online.

Content is not restricted to anchors; major sections focus on the rest of the anchoring system – chain, rope, connectors (shackles and swivels), windlasses, etc. Optimising rode make-up, best practice anchoring techniques, multiple anchor rigs, tandem anchoring and optimising the scope and catenary of the rode for best anchor performance are just a few of the topics covered in-depth.

Mobiletide

handsetsmallMobiletide is a Java program designed to run on your phone without need to connect to the phone network (GSM) or the internet (GPRS) – just as well !

It has a database of worldwide locations and can display a tidal curve for any location without you having to reference tide tables or do any standard port calculations.

The makers list a broad range of mobile phones that are supported, but basically any phone that runs a Symbian or Windows Mobile should suffice since they will then support internet connections and also Java software.

Mobiletide is synchronised to the moon’s daily cycle of 24hrs 50mins and 28 seconds. On average across a Lunar day (month) this is how much the tide moves on by each day. Working to an average tidal progression means that Mobiletide will remain accurate over a longer period of time, so in 5 days, 5 months or 5 years mobiletide will still be showing the correct tide. It does mean that throughout a month Mobiletide will fluctuate in and out slightly, however it will remain within 0-30mins for the majority of the time.

There are other influences on sea levels that affect exact tide times and these should be taken into account e.g. Strong on / off shore winds; Changing volume of river flows; Atmospheric pressure

Due to the variable nature of tides mobiletide is only intended as a guide to tide times. If you do have internet connection however, then the makers claim that Mobiletide has direct links to the most respected swell, wind and weather WAP sites around the world, providing the whole detailed picture.

Windlass or no

I was also considering installing a windlass but I knew that that was the type of job that could lead from one problem to the next and so I was more cautious about that final step.

The anchor locker lid would need strengthening, or modifications made to the area of the deck where the roller reefing mechanism attaches – all sounds too elaborate – first rule of DIY applies – KISS !

According to Lewmar the calculations of weight of anchor, rhode and corresponding windlass look something like this:

…………………………Anchor Calc

All looks pretty straightforward – apart from the installation, I decided it wasnt worth the hassle, and my 1st mate (wife) can continue to haul the anchor….well someone has to do it !
