I have used a compass for my Laser, but since I haven't used so-called a tactical compass, I do not understood how it works. The two compasses I am considering are:
• (a) Nexus 103RE: Nexus 103RE Racing Compass
• (b) CarbonParts: The CarbonParts Laser Compass | CarbonParts
First question about 103RE: it is said that “with 103RE you only need to remember one number whether port or starboard”: green scale from starboard side and red from port side - both are supposed to show the same number. How does this work? It looks that the green number is +80 degree of red one, and the two markers are 80 degree apart. So green number and red number are the same, if the boat is stopping. But what we want is the green number while sailing starboard tack in closed hold and the red number while sailing port tack in close hold to be the same?
Second question about CarbonParts compass: The compass itself is from Plastimo (Tactical compasses - Compasses - Compasses, Electronics & Navigation | Plastimo), which divides the 360 degree into 4 colored segments, each of which has 0 - 5 numbering. CabonParts’ web site says “This makes remembering a particular number much easier and works regardless of what tack you are on.” Again, how this works? Since each region is 90 degree apart and the markers seems also 90 degree apart, at any moment, they will show the same number in different segments. But the reading while actually sailing starboard tack and port tack will be completely different, won’t it?
The third question is about recommendation: It looks that 103RE have been very popular for Laser sailer, but watching the recent world cup event in YouTube, I seem to see more sailers are using CarbonParts, if I am correct. The example video is
, women’s radial race from 4:25:00. Does someone have actual experience of this compass? It looks like a good-looking lightweight compass that will be also handy to carry, but is this practically useful?
Thank you very much in advance,
Toshi
