I always get a chuckle out of boats where the designer and/or builder has decided that windage simply isn't a factor for them. I guess if it your intention to only go downwind and never need to claw off a lee shore in threatening conditions, you'll be fine.
If you're blasting off from Cannes to Monte Carlo for a late lunch and maybe a few games of chemin de fer, a typical float plan goes something like this:
After you've cleared the breakwater, light 'em up for a demo fly-by of Iles Sainte-Marguerite and Sainte-Honorat giving a good show for the picnickers and sun-bathers.
Drop down from 60 knots on the turbines to 15 knots on the diesels once you're out of sight of Ile Sainte-Honorat. Your guests can now relax their grips on the handrails and cocktails can be served by the staff.
Proceed at 15 knots on 51-degrees true for about 70 minutes.
Light up the turbines again for the last 4 miles to the entrance to Port Hercule (Monte Carlo Harbor).
By following this float plan it only costs about $1,000 in fuel instead of $3,000, not that that miniscule fraction of your daily operating costs matters that much; for those frivolous afternoon jaunts, it's all about giving your guests a thrill while keeping them comfortable.
After the crew has secured you to the center quai, all the gawkers on land will be expecting to see Maximillian Largo step ashore.
P.S. You won't be the largest yacht there. By a long shot. Sorry.
P.P.S. You will be the most awesome, though.
My favorite scene around Newport Beach, CA, is the noobs in the rental Hunter 17s.
Not a summer weekend goes by without some hapless beginner standing up in the very back of the boat, bow fully a foot out of the water, boat in irons, drifting backwards, sails luffing in the gentle breeze and the pilot pointing frantically dead into the wind screaming at anyone within earshot, "I just want to go that way! I just want to go that way!" They drift back enough to pin the rudder hard over, the sails eventually fill, and the boat starts moving forward on a beam reach. Elated, the pilot immediately steers the boat directly head to wind.
If I'm near enough not to have to raise my voice, I'll gesture with my hand at 45-degree angles and say, "You have to attack it in chunks."
They repeat: "But I just want to go that way!" again pointing directly into the wind better than the most accurately calibrated instruments I've ever seen.
I look at them squarely in the eye, slowly shake my head, and say, "Not going to happen."
If I, too, am sailing to windward, I'll say, "You have to sail at the same angle I'm sailing. Follow me."
