I've been aboard both as friends had the 34s and the 36s.
Big difference as Alormaria points out. The 36 has at least one more foot of beam.
34 is 11'9"
36 is 13'2"
plus the extra length. THe beam adds a lot of room including in the E.R.
Listings for examples below.

Don't let the names fool you as those hulls were the same for many so called different brands. Just the details of how they were finished inside and the equipment aboard.
You need to see them to understand the difference.
I can't help you with the seeing though as I don't have one and am on the wrong coast.
But check listings as they will show up but you will have to make the trip for comparison.
Good luck and happy hunting.
