I have not owned particularly flash calculators and never any with dedicated nav capabilities. For most of my actuarial career I used HPs, in particular the 15c and 12c models. But in recent times the quality of those fell in the gutter. I am now happy with my old school days Canon F-73P. Amazingly it works as if new. It has all that I need: a couple of short programmable memories into which I have coded Hc and Z calculations, 7 memory registers and the very handy rectangular to polar coordinates function which gets most use of all under dead reckoning. For on my little ship, most nav is dead reckoning, followed by pilotage and cel nav brings up the rear. My gps plotter failed some time ago and I haven't seen the need to replace it yet, given gps coordinates are on my watch and my phone if needed.
