I have a 2003 Worldcat 270TE with twin 225 Honda 4 strokes. Best boat I've ever had for running offshore. Have been getting 1.6mpg consistently but replaced the high & low pressure fuel filters at end of last season so hoping to get better this year. The boat handles moderate seas very well, but I don't think I'd want to be out in 4-5's in it (or any other boat for that matter, except maybe the 72' steel hull shrimp boat my Dad built back in the 80's!). It does get a little squirrely in a quarter following sea. An autopilot is a must otherwise you'll have quite a workout fighting the wheel. My Simrad autopilot is an older model and a bit finnicky. Upgraded all my electronics last year & now thinking about replacing the AP as well.
Absolutely love how much fishing room the Worldcat has. Nice high bulwarks too, and I'm a tall guy so that's appreciated. Nonskid deck that's easy to clean, and doesn't cut your knees to shreds. WC also went the extra mile with the little things....easy access to pumps, wiring, etc. Only complaint I have so far is the macerator pumps can NOT handle fish scales. The pumps don't cut the scales up at all, and instead they end up plugging up the discharge port. Burned up several pumps this way. WC routes the discharge lines in a loop up the bulwarks behind the rod holders (so the boat doesn't sink if you lose a hose clamp). At the top of the loop they have a fitting which restricts the discharge line quite a bit. I took those fittings off & installed new discharge lines with no fittings. This helped some but the lines still gets plugged. Only solution I came up with was to put a plug in the drain holes or rig a screen over them so you can scoop out scales before pumping them out, but that's a PITA. Anyone else have problems with this? I know this question belongs in a separate thread.....
The last thing I'll say is, the Worldcat folks are OUTSTANDING when it comes to helping their customers. You'd think fittings, etc. for a 2003 model would be hard to find but anytime I've ever needed anything they come through like a champ. Last time I ordered something (specialty PVC valve for the live bait well), they sent me two of them via overnight mail and didn't charge me a dime. Now THAT'S service!
