Picked a mid-range one last month for a family thing, around 55 feet, and it was perfect – plenty of room to lounge without feeling like we were rattling around in something huge. The smaller 40-ish footers are great if you want that intimate vibe, super easy to maneuver into quieter spots, and way cheaper per hour. But yeah, for 10 people with coolers and gear, the extra space on bigger ones makes it more relaxed. Checked out some best yacht companies yachts for rent and they have solid variety that fits different group sizes without breaking the bank. Ended up grilling snacks on deck while watching the skyline light up – total win.
