I use the Sextant OR (original), it's pretty heavy, I attach it to the mast with a lanyard cause if you lose it it sinks being made out of brass. Only downside is when you can't see the sun on a cloudy day, the maps I keep rolled up in the tramp pocket, they kept getting wet so I had them laminated. As for speed, I judge that by the height of my rooster-tail, 4' tall = going fast, 6' tall = going damn fast.
