I would of killed for a 2830 but the only"ONE" for sale was in FLA and it was too much for me !!!!
I spent 6 months test driving 2520/2530 and setteled on a 2820!!!
I wanted to be able to fish with 5 - 6 guys and not be on top of each other
I wanted to add a live well with a seat and not crowd the deck
I wanted to be able to take 12 people on a harbor cruise
I can do all on a 28'parker
The 2520 is amazing
but the cabin is like mine a little too small for 4 people going off shore...
The 2530 amazing but forget fishing 6 people on that if you have a live well
The 2820 was a compromise 4 me but thats all i could afford
The 2830 TAH DAH!!! would be the BOMB!!!
BIG cockpit big cabin
GAS milage from the 2530 to a 2820
563 lb difference , same beam !!! not ,much of a difference in fuel consumption unless u r running like a maniac or in rough seas
shorter range on 2530/20
so that is my 2 cents!!!!
You will be a happy go lucky guy either way....
