New this year was the addition of the Nexus Race Box. The RB is a nice addition to the instrument server in that it allows us to add our polars to an SD card and display that information on our cockpit instruments. I set it up so that we display Target Boat Speed rather than Polar Boat Speed. My opinion is that with as much as the boat is pushed around by any given sea state the Target Boat Speed (calculation based on actual wind speed, direction and course sailed provides a truer picture of what the boats performance should be versus a theoretical number assuming all variables are constant). It also provides start line information and optimum angles of sail. The start timer is also a great feature when configured with buttons at the helm. I find that the Target Boat Speed is by far the most useful reference point. It was a very easy instrument to install and the support from Nexus was excellent. We received the third unit off the production line and Nexus provided updates for all the software glitches we uncovered in a matter of days.
In order to meet the Offshore rule for a separate power source for navigation lights I installed a third battery bank (33 amp hour battery) and electrical panel that powers the Navigation lights, electronics and emergency strobe light. The bank is tied into the boats charging system and can be charged under power or connect to shore. The rule only requires that the lights have their own separate power, but the panel had two additional breakers and it seemed like having the option of having the radio and strobe available in an emergency were a good idea too.
