I drive from Niantic to the Race 3 times a week from May 1 to September 14th in a 2520XL and I love it, i troll and i drift and i drive around for fun and i take the kids tubing, stuff like that, plus 70% of my boating time is in the dark
I can only recommend anything to me because everyone has different opinions/expectations, etc., also, I only have really good experience with my 2520, before this i had a 20' center console which was horrible to drive, it was a 2000 Hydrasports
The reason I went with the 2520 XL is cuz cash was an issue, I wanted brand new, I wanted to pay cash, I wanted the best fuel economy and the least cost of ownership, if cash were no issue at all i would buy the 21 degree boat, just cuz it has to be better, right, but in my own mind i can't see how one would be that much more or less stable than the other when drifting, just like in the end i doubt that the ride is miraculously better in the 21 degree boat, it is probably better but i also would have trouble measuring it, so, in the end the $18,000 dollar difference (or something like that) was just not worth it to me, plus the engine maintenance would be $600 more per year, plus when i have to put a new engine on the back it will be a lot less than putting new engineS on the back
I can only speak to my boat for fuel usage but on a typical day when i am driving out to the race at 25 mph with a couple of my big fat friends I am burning about 10 gph, I always imagined it is less than the 21 degree boat would use but since I never owned one i can't say for sure
how's that for a non answer
