You should be more than fine in your boat if you use some common sense. I have a 16.5 foot lund and other than when I may wish to travel a distance, might I wish for a larger boat. Truth is if your 16 or 17 foot boat is finding it too rough just about any size boat will not be enjoying the fishing, If I were a first timer I would fish either big bay or Hay Bay and the Mouth of Hay Bay in June. I mention Big Bay as the fish are pretty much scattered across it and I find it is pretty easy to catch fish from one section to another so no need to find the spot on the spot. Simple tactic is to look for the new weeds coming up and focus on them and the edge. In June I find most walleye along the new weed growth. Depending on wind I would suggest to modify where you fish to stay out of any big waves. If winds out of west fish west side by rush bar, if out of north fish northside etc. The depth is pretty consistent in Big Bay as well and I would focus on humps in the 10-15 foot range and the main basin around 18-20. My go to when on a new body for Walleye is bottom bouncers (2 oz weight with spinner with float) however you will need an electric motor to get down to speeds in the 1-1.5 mph. Standard Trolling and jigging also work so go with what you know. Hay Bay is also very nice and one of the more protected bodies of water. Fishing seems to be getting better over the last few years and June is my favourite time of year to fish on Quinte in a boat and usually get the biggest numbers at this time. ( Ice fishing on the Bay is still my favourite
)
Good Luck.
