The Jeep Cherokee (not grand) is a great true small SUV. We still use our 1997 Jeep to haul equipment for my business and pull our 23.5 ft. Caravelle Interceptor. Something this size as a hybrid with enough HP and torque is highly feasible. At 23 mpg, it's already a very reasonable and functional work vehicle.
On the other hand, boats are not fuel efficient and we've seen a great reduction of traffic on the waterways. We filled up the tank for $120 last weekend, drove the boat under 25 mph. (65 mph top-speed) for about a mile, anchored and stayed in one spot all day. weee! At least we have enough gas for a few more floats this summer. No cruising.
