Rick, I will be very interested in what panels
you go with, I am looking for panels
as I write, our boats are similar in size and equipment
so let me know what wattage and voltage you go for.
You have an arch so it should be a breeze.
In particular I will be interested in what voltage and wattage you go with, some say stick with 12 volt nominal (17 to 18 volt) panels others suggest higher voltage with a MPPT
controler. I understand the lower voltage works better with any shading.
