Not positive but....
I've got a 22 pound Lewmar (bruce style) on my 32-3 roller, It fits no problem, although I added a small SS plate on the deck so the anchor was not resting directly on the deck. With a 33 Bruce type I think you'd be ok, except for where the shank comes back on the deck, there could be 2 issues, the shank resting on the deck which could be easily handled as I described with a small SS plate, the second would be the length of the shank may be long enough that it would rest on the top of the anchor locker, making it a pain to open the locker, this should be easy to measure and check. I've been happy with mine, I don't anchor a lot, but it is easy to use, sets pretty quick and seems to hold well.
