Bob,
Congrats on enjoying your boat! We’re still lovin’ it after 8 years with ours.
The rooftop AC option is certainly the most convenient by far. We have a Honda iu2000 but don’t use it on the boat, although many Brats do. It could power up to about a 10-13.5K (with luck and a smart starter) BTU rooftop AC. Our 15K Coleman BTU unit is overkill for a TomCat, but it sure cools it down quick at a marina on shore power. You’re limited to 30 amps total, so you have to do some load management...like not running the water heater with the AC on.
If you want radar, of course it has to be above the AC unit, and any GPS antenna has to be above the radar beam, and also your anchor light must be visible in all conditions. Mine is mounted so it can be folded over, otherwise it’s over the 13.5 foot federal height limit when on the trailer. If you also want dinghies and SUP’s and solar panels, plan ahead.
Our Best Cruise To Date was the NY-Canada historic canals Triangle Loop. You must get your air draft down to under 8 feet to take the fabulous Lachine Canal through Montreal. We did it by removing the radar dome (4 bolts and 2 cables). We had never heard of cruising the Great Loop when we bought our boat, but now we’re Life Members of AGLCA. Keep your options open!
I think my hatch is a Bomar, and the Bomar screen attaches to the underside.

Mine is the only TC255 I’ve seen without the oval berth portholes; sorry can’t help you there.
We like a 3” foam topper in a washable cover to go over the berth cushions. A Queen size will stick up the forward corners unless you cut it. Now we’re using a Double, which leaves some room along the sides for storage bins etc. but still allows opening the three forward berth hatches. I’m over 6 feet, but have plenty of room. We sleep athwartship.
We’ve come to really like Deckadence marine ‘carpet’ despite it’s higher initial cost. Sand, dirt, etc goes right through it, out of sight and out of mind. It’s soft on bare feet and immune to Clorox etc. We also use it in the cockpit. Believe it or not, we roll up both cabin and cockpit pieces and stuff each into a hi cap commercial washing machine with hot water for $6.50 and Clorox and it comes out sparkling! Cut it with a new utility blade. We started with Artic White, but after three heavy duty years we had a bit of a wear pattern visible down the cabin walkway. We changed to silver and have no issues over the past five years. ‘Normal’ owners would not have been bothered by it.
