Fairly new to vessels this size. I've had a 30' Carver and 39' Sea Ray vintage 1980s. Anyone have general reliability / sea worthy comments on this Marquis and/or it's Volvo D12 ECS 775s? I've read some negative feed back on other forums... for instance, one story that is on several is of a vessel being Captain transferred from NY to FL, hitting 5-10 foots and having both hull windows shatter due to "flexing so much". Will fully survey of course, but wondering if this is an overall decent vessel for full time liveaboard loop/Caribbean use? Fuel economy? Ride?
