You can access the pair of 380 hp Cummins MerCruiser Diesel engines in two ways: Reach standard maintenance points via the day hatch in the bridge deck or lift the deck for more serious work. Power options include MerCruiser DTS gas engines rated at 375 hp each and those same CMDs coupled to ZF pods and joystick control (an $81,000 upgrade).
The cockpit sports quick-release freshwater and saltwater washdown fittings. Under a hinged teak armrest are the battery switches. I would like to see them either boxed in or moved. They look ugly alongside the other sleek, polished fittings. And for security, I prefer my battery switches to be hidden or locked away.
Tiara lays up the 3600 Coronet by hand, using solid glass below the waterline and end-grain balsa coring above the waterline. However, the deck and other parts, like hatches, are resin-infused and gloss-finished on both sides. It’s all then coated with Imron paint for durability and beauty.
