The Catalina Yachts 34 MkII 2006 vs Catalina Yachts Catalina 380 - Fin Keel Fin Keel 1987 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
Size is the most obvious dividing line here. The Catalina Yachts Catalina 380 - Fin Keel Fin Keel 1987 measures 38,6 feet overall (1987), giving it roughly 4,6 additional feet of deck space compared to the Catalina Yachts 34 MkII 2006 at 34,0 feet (2006). Weight tells a clearer story for trailering families: the Catalina Yachts Catalina 380 - Fin Keel Fin Keel 1987 tips the scales at 19 473 lbs — 7 473 lbs less than the Catalina Yachts 34 MkII 2006 at 12 000 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.
Both boats share a closely matched power ceiling — 35 hp for the Catalina Yachts 34 MkII 2006 and 42 hp for the Catalina Yachts Catalina 380 - Fin Keel Fin Keel 1987. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup.

The Catalina Yachts Catalina 380 - Fin Keel Fin Keel 1987 is rated for 11 passengers, while the Catalina Yachts 34 MkII 2006 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Catalina Yachts Catalina 380 - Fin Keel Fin Keel 1987 could be the deciding factor.
Displacement is where these two sailboats genuinely part ways. The Catalina Yachts Catalina 380 - Fin Keel Fin Keel 1987 displaces 19 473 lbs — a 7 473-lb difference over the Catalina Yachts 34 MkII 2006 at 12 000 lbs. That gap separates two entirely different categories of sailing: the heavier boat is built for offshore passage-making and load-carrying, while the lighter hull rewards performance sailing and easier handling in lighter air.
Draft is a practical consideration that many buyers underestimate until they're already at the marina. The Catalina Yachts Catalina 380 - Fin Keel Fin Keel 1987 draws 7,0 ft, compared to 5,3 ft for the Catalina Yachts 34 MkII 2006. That 1,8-foot difference affects which anchorages you can access, which haul-out facilities will take you, and how carefully you need to read the tide tables in shallower cruising grounds.
For auxiliary power the Catalina Yachts Catalina 380 - Fin Keel Fin Keel 1987 carries a 42-hp engine against 35 hp on the Catalina Yachts 34 MkII 2006. Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.
Bottom line: The Catalina Yachts Catalina 380 - Fin Keel Fin Keel 1987 is the offshore and bluewater choice — at 19 473 lbs displacement and 39 ft it has the load capacity, range, and seakeeping for extended passages.
