I can't recommend specifics on where to get a batter / what brands, as I'm in the US.
To the question of 1 battery or 2, I'd say it depends on specifics of your use. Do you own the boat or are you hiring one? How much do you fish, and on what size waters? Do you use a boat that has a petrol outboard and the electric is just for fishing use, or is it the primary power?
Assuming you don't own a boat, the biggest issue with 110+ AHR batteries is that they're heavy. Loading and unloading them could be a real undertaking depending on how close you can get your car to the boat and the docking setup.
BTW, in general I think more = better when it comes to battery AHRs. If you can get a 115 or 120 Ahr for little extra money, I'd do so.
At the very least, I'd recommend getting a good folding cart if you'll need to carry the battery any distance to get it to and from the boat.
But with that said, two 85 AHR batteries is going to have its own set of problems. Now you have twice as much care and feeding. If you ever need to charge the batteries overnight for consecutive days of fishing, you'll either need two battery chargers or you'll have to rig up a set of jumpers so that you can charge both batteries with one charger.
I'm also going to speculate and say that two 85 AHR batteries could well weigh more in total than a single 110 AHR battery. I could be wrong, but it's worth thinking about because it just adds to the hassle factor.
If you don't already have one, I'd also say budget for a good battery charger and in my boats that don't have a built in battery compartment, I always put batteries in a plastic battery box to keep them out of the weather and if they should leak, the box contains anything that spills. Also, if you do any higher speed running you need the battery box to have a hold-down strap.
