Great boat, BIL had a 31 Tiara with 454's and it drank the fuel but traded for a 35 Pursuit w/diesels and it's the nuts. 95 miles out of NJ to the canyon for tuna, troll all day and burnt less than 200 gallons. Good luck on finding the one you like.
I have been running a 41' Tiara for 3 years. Be for that I ran a 45' cab for 3 years. The Tiara has better Sea Keeping ability by far. The only thing I miss is the 800HP CAT in the Cabo. As far as the boat it self goes the rides better in a Head Sea and soil as a rock.
I do think the Cabo looks cooler But Better to feel go then look good. The Newer Tiara have got away from SportFishing there more of a Wine & Chese boat. They have a lot less cockpit space=less fishing room.
