TZ is an entirely new piece of software. I recently read that it shares no code with the legacy Maxsea (12, etc). Nothing in common whatsoever. It was a complete re-write from the ground up, which probably explains some of the earlier teething issues as well.

Do you think there's a chance these skippers simply wanted to stick with they already knew? some people are pretty stubborn when it comes to software

possibly. some are a die hard bunch and still have decca plots they use :o and have disk after disk of routes done in every flavour of plotter imaginable. maxsea 12 opens these no problem. TZ doesn't. I'm talking systems like Trax, Fishmaster shipmate etc

but they do like to have the latest toys though and aren't shy of spending a few quid. most that run maxsea v12 have also bought olex (£4000 +) to run along side maxsea as maxsea's 3d stuff sucks by comparision. I reckon some of them were hoping the TZ 3D would be a big improvement so they could drop Olex (which is also a Linux app with all its added complications)
