We really battled with how to mount our Raymarine last year. I did not want anything that distracted from the beauty of the Ericson lines. And I did not want to add a lot of weight up on the mast. I walked around the marina and payed attention to all the boats on SF bay over the season. After reviewing all options, I decided on the Questus mounted on the Backstay. Allen (the owner of Questus) provided quite a bit of support during the installation process. The Questus is not a simple unit, but thus far I am satisfied. I hated the poles mounted on the stern of sailboats and the mast mounts did not appeal to me. For a backstay mounted unit, you have two choices, Questus and (the other guys- Walsh I believe.) My Questus was not cheap but it looks and performs great. I did order the 3' extension to raise the unit further up the backstay. I did this after the standard pole was installed. I installed the unit myself.
