The topic was sailing instruments, and he was interested to know which are necessary and which should be considered expensive fluff that a cruiser can happily live without. It seems that the young man had a good head on his shoulders when it came to the value of money and didn't want to part foolishly with his money for unnecessary gear. But he didn't want to scrimp at the expense of putting himself or his boat in danger either.
For highly competitive racing sailors, the answer to this question is moot—the more information disseminated to the largest number of crew, the better. Gaining a few tenths of a second means that every trimmer needs to focus on the VMG repeater or some other bit of information streaming from a computerized data center. Even the casual Wednesday night beer-can racer will want at least the basic performance information.
But what does the true cruiser need? And in what order of importance?
When the young man asked what I would put on my own boat first, I had to think about it for some time. The microchip revolution has changed the whole landscape of sailing and some assumptions have changed forever. Twenty years ago, I would have undoubtedly responded immediately to sink those hard-earned dollars into a good knotlog first. At the time, it was the best tool available for DR navigation, and that was the only kind of navigation we had most of the time.
No. 2 would be a good depth sounder. Some sailors hardly use depth information, which I've always found odd. It not only keeps you out of trouble, but it gives you information regarding the proper anchoring scope. With the addition of upper and lower alarms, a depth sounder can be used to navigate a long inshore passage, and we often use ours this way to run south along the Florida coast inside the Gulf Stream. At 100 feet you're too deep and risk bucking a three-knot current and at 25 feet you're too shallow and risk running aground. Love those alarms.
We sometimes use depth information for "quickie" navigation rather than plot GPS coordinates on the chart. Just take the information from the depth-sounder display, locate the same depth pattern on the chart, and you have a pretty good idea where you are.
In third place, I would insert the knotlog back into the picture. So if we have speed on the GPS, why would I want to spend another $500 and have another hole in the hull just for a second way of guaging speed, you ask. Good question. The two speeds are different, and that difference creates a navigational opportunity. The GPS measures speed over the ground while the knotlog calculates speed through the water. Assuming that both are properly calibrated, the difference makes it possible to vector current speed and direction.
The knotlog also makes "quickie" navigation easier and has uses when logging in. Besides, it gives bragging rights to the bored night crew who watches its little numbers flash by, looking for the best speed. Seriously, it gives even the cruiser a good idea whether changes in sail trim or steering angle are beneficial or detrimental to performance. This can shave many hours of time off a long passage by helping you to squeeze the best speed out of the boat.
There was a time when wind direction instruments and wind speed instruments were two distinct units. And there was a time when I laughed at both of them. But many modern cruising boats have very complete and sophisticated dodger and bimini systems that make seeing a masthead-mounted wind arrow impossible, and these protective devices also mask the true strength of the wind.
There are those sailors who simply have to know how hard the wind is blowing to the exact knot. They memorize the wind ranges on each sail and a few have little numbers on the roller-furling line to match with their wind meter. To my taste in sailing, I found that even the Beaufort wind scale presented too many categories, so I invented the Wood Wind Scale for Non-performance Cruisers that looks like this:
|"Many cruisers with wind speed and direction instruments on their boats claim that once it's in front of you, the tendency is to become more performance-minded, making faster passages as a result. "|
2- Beautiful day for a sail.
3- Time to reef.
4- It's too damn rough out here; let's look for shelter.
When you use this scale, you have no need for wind speed, but since it comes rolled in a package with wind direction, you may end up with it anyway. Many cruisers with wind speed and direction instruments on their boats claim that once it's in front of you, the tendency is to become more performance-minded, making faster passages as a result.
That may be true. But with that extra equipment budget and my rather lackadaisical attitude toward performance, I'd rather have radar. Radar is not only a safety and collision-avoidance tool. It can be used to spot and avoid the worst of thunderstorms and squall lines. It gives comfort and peace-of-mind in fog, rain, and reduced visibility. Radar serves as another navigational tool, extending your eyes to find buoys before the binoculars can locate them, and makes entering a strange port at night much safer. The lights of businesses, condos, and highways along some shores have become so intense that finding nav aids when coming in from sea is almost impossible.
So, my personal choice for the No. 4 spot would be a small radar set. If there was still money left in the budget, I'd probably put the wind instrument set in at No. 5.
When I think of cruising, I automatically think of somewhat restrictive budgets. I realize that a new breed of cruiser is coming on the scene, armed with buckets of dollars and a desire for the latest technology. If you are one of these, disregard everything you have read above about budgeting and buy at least one of everything. Then add a laptop with computerized navigation software, a color chart plotter, and interface everything into the autopilot. In a few years, it may be possible to automate the boat to sail herself entirely so that these sailors can stay in the comfort of their house and watch the cruise on their webcam.
