why raise deck floor?

[rcoster38]

it seems to be more commonly done on the 20s and 18s ( I raised the deck on my 20SF by 2.5" for self bailing purposes). I don't own a 23 so others please correct me if I'm wrong, but I believe wet decks are less of an issue on the 23s

I've read plenty of posts about raising the decks. How does the reduced freeboard feel with decks raised up 2.5"? I recently hung a 140 Zuke on my 20 SF and I'm seeing more wet decks than before. I would think a couple of those ping pong ball scuppers would be a less expensive correction.
