It took a while and we did some extra miles to be sure we did not get run over or hit something. BTW this epic voyage predated DECCA let alown GPS.
Don't get me wrong a compass is an essential aid to navigation for yachts, mobos etc as is the ability to do "steam" navigation with charts, tidal diamonds, leeway, eps, dr etc etc. However there is a world of difference between that and an open and high speed boat like a RIB.
SWGINN you are welcome! At the end of the day it comes down to personal preference and if you want a traditional compass fit the largest and best damped one you can. And as Lester says fit it in your line of sight for easy viewing whilst driving. Mebbe on the front of the console on a gimbal mount so you look over the top of the console at it?
