The Concept 36 Open Deck Series 2013 vs Concept Yachts 30 2005 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.
The power gap is worth calling out. Rated to 900 hp, the Concept 36 Open Deck Series 2013 has a 675-hp advantage over the Concept Yachts 30 2005's 225-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Concept 36 Open Deck Series 2013 carries 225 gallons versus 15 gallons in the Concept Yachts 30 2005. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Concept 36 Open Deck Series 2013 is rated for 10 passengers, while the Concept Yachts 30 2005 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Concept 36 Open Deck Series 2013 could be the deciding factor.
Bottom line: Choose the Concept 36 Open Deck Series 2013 if your priority is putting more people on the water — it handles 10 passengers and at 35,3 ft it has the deck room to back that rating up comfortably. The Concept Yachts 30 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.
