I have TC255 Triton Hull # 0001 (now that was optimistic thinking, wasn't it?) with a Pooderbuilt (prior name) bracket that angles up just as much, see Pic #30 in my album. I had some paint blistering resulting in an $800 sanding/paint job I'm sure is due to Pettit Ultima (good paint, but 55% copper and should not have been put on the aluminum bracket even with Intercoat epoxy coatings under it).
I'll defer to Marc, but I think your issue is the deck scuppers are so close to the waterline at rest. Don't change brackets, they have little to no effect at rest. Keep the boat.
Interesting, I have never seen another TomCat with no NO cockpit railings, and mine was previously the only one I've ever seen without boarding railings (custom installed 2 yrs ago).
Happy Boating!
