I've got to be honest: I hate boats. I get seasick like something awful even in the calmest of waters. However, I'd probably down a whole bottle of Dramamine for the opportunity to board the G180 from Ghost Yacht. This sleek 55 meter superyacht looks like a next-gen US Navy cruiser. Made of aluminum and reinforced composite materials, the G180 can cruise at 15 knots with a top speed of 23 knots. You and your 12 guests can cruise in luxurious accommodations for up to 4,000 nautical miles. The yacht even has its own swimming pool and helipad. Read more about the G180 at James List.
