You can get a pretty good idea of how the boat may or may not tow with your jeep by some quick research
1. Check the owner's manual for the Jeep and get the rated towing capacity. SUVs might be rated from 2,000 lbs to 5-6,000 lbs. Depends on the size of the SUV and whether or not that model has some of the towing options like extra size radiator, oil
cooler, heavy duty suspension, and limited slip differential. So you might need to figure out exactly what options package came with your jeep.
2. Get the weight of the boat and trailor.
3. What kind of hitch on the jeep? Bumper hitch has a minimum tow rating. A receiver hitch bolted to the frame will handle a lot more weight.
4. Does your jeep have a 4, 6 or 8 cylinder engine
Rough guideline, the boat your referring sounds like a 28' with twin engines. If so, you would need a pretty heavy duty truck to tow that. You might be OK towing slowly a few mile to a ramp
but you might find that you could get the boat in but not be able to pull the trailer back up the ramp
