For giggles, I checked Tracker's website. The Grizzly series, 1648 SC (single console NOT a walkthrough) comes in at an average weight of 1395. That would be boat, motor, trailer. Now start adding gas, battery, safety gear, and spare tire as you do not want to be that guy/gal on the side of the road with a flat with no spare, etc. You're over your tow rating on your CRV.
I really would heed the advice above about the CRV not being the choice vehicle for your particular setup. Its not just that its over limit, but think of it in terms of steering. For max steering effort on your tow vehicle, your front end needs to be planted. As you add tongue weight, to avoid trailer sway, you are lifting the front end of your CRV up in the air taking away some of your steering ability.
We're not advising you go out and buy a Ford/Chevy/Dodge 1/2ton pickup to pull this load but rather you may want to look at a larger SUV and not a CUV to tow with if having a console boat is your end goal. There are plenty of mid sized SUV's out there that are more than up to the task....Toyota Highlander, Dodge Durango, Nissan Pathfinder, Chevy Traverse (make sure it has the tow package), just to name a few.
