Questions
Lagoon 42 Millenium: what buyers ask us
How long does it take to get a new Lagoon 42 Millenium?
It depends on the route. A boat already in stock usually takes about 4 to 8 weeks, mostly commissioning. A hull Signature has already reserved at the yard takes about 4 to 9 months, and a new factory order built to your specification about 11 to 14 months or more. Ask us which Lagoon 42 Millenium hulls are in stock or allocated right now. How long it takes, step by step →
Can I see a Lagoon 42 Millenium before I commit?
Yes, and you should. We run in-water viewings and private open houses through the season across Newport, Sag Harbor and Hayes, and we are at the Newport and Annapolis shows. Out of season, ask for a Live Tour: we walk you through a boat by video call.
Do you help with financing and insurance?
We introduce you to marine lenders and underwriters who write multihulls. We do not broker the paperwork ourselves; we make sure it starts early enough not to hold up a delivery.
Can the Lagoon 42 Millenium pay for part of itself?
Charter-managed ownership is a real structure, not a marketing line, but it carries conditions on use, income and participation. Our Boat as an Active LLC page sets out the conditions that disqualify people as plainly as the ones that qualify them. Your accountant decides whether it applies to you: this is not tax advice.
