As stated, one has an 8'6" beam and the other 9'6" beam. One is legal to trailer without permit is most states, the other will require one to be legal.
Can you trailer the bigger one without a permit, well I guess so and several indicated they have done this on the site. I would recommend against it for several reasons.
- If anything happens, you will have some explaining to do at best to the authorities and your insurance company and may not be covered.
- LEOs are boaters too and some may know the models to watch out for (read on THT before).
- Hull consideration. I'm not bashing either but you will need to ride them in the type of seas and environments you plan to use them in.
- Layout. Probably close but 1' in the beam is huge. I'm sure it translates into a much "bigger feeling" boat. Are there must have features in one vs the other?
- Cost. With size, cost goes up exponentially. Is financing in the picture? Is there other things you can do with the delta cash or are you awash in it and want the bigger one?
- Fun. Big is nice, bigger is nicer but are you really going to have that much more fun in your boat for the additional $?
- Tow Vehicle. What do you have? More importantly what does each require? Will it comfortably tow both boats? Do you need a new trailer? Is there much cost delta?
- Value post sales. Poster makes a great point. Which one sells faster? I'd say an 8'6" beam boat sells faster all day.
- General advice: Buy the biggest boat you can comfortably afford, more so if buying new. You will get 2'itis, well in this case maybe 1'itis until you find the boat that best fits all your needs. New boat depreciation is steep. Is one of the two avail at a dealer today? I'm a big believer in getting a better deal on a boat that a dealer has versus one you are ordering.
Just my 2 pennies.
