Is there an animal that meets these requirements?

Any idea how big a coastal gets weight wise? Less hefty than a red tail boa?

The biggest I've ever owned was 9-10 foot and weighed in at about 25 lbs. generally they top out a little smaller than this, I have a few coastal females in the collection now that are about 8-8.5 ft and I'd guess about 20 lb. Males are generally smaller.
