Ok, all jokes aside.
First of all, the "Avoid Atomic 4's at all costs" advice is just nonsense. I, and many of my friends own them. They've been ticking on sailboats for 40 years, safely. They are no more dangerous than gasoline engines on powerboats. Most recreational powerboats are gasoline powered.
Personally, I'm not biased towards either gasoline or diesel. If my boat came with a diesel, depending on the brand, I'd be perfectly satisfied. Instead, my boat came with an Atomic-4 that runs like a Swiss watch, and I am perfectly satisfied with it. Why not visit the Moyer Marine
forum and decide for yourself?
Heed the advice about the "mile off shore" discussion.
You don't "park" in the ocean and go to sleep. A vessel in the ocean is like a shark: Keep swimming or die.
In order to keep swimming (sailing), you need to maintain a continuous watch.
Solo sailing in the ocean is something that takes experience and practice. It takes time to develop routines that allow you to safely nap and sail and maintain a lookout. Even then, there are people who declare that solo ocean sailing is illegal, and unsafe. That's a debate for another time though.
Sailing is like piano-
You can learn how to bang the keys or pull the strings in an afternoon, but you'll spend the rest of your life, perfecting the craft.
That statement is not meant to discourage you. Quite the opposite, I urge you to embrace not only sailing, but good seamanship. Take pride in mastering the skills and practices that make a good sailor. You can learn to sail for recreation quickly and safely. The more advanced levels of single-handing, and ocean sailing take a little time and experience to safely
acquire, but not terribly long at all.
Yes, there are people like the Bumfuzzles who simply fell into a boat and crossed oceans successfully. The Bumfuzzles laugh at people who urge caution. There are also countless people who fell into a boat, sailed into the ocean and sent Mayday calls, begging for rescue. Some were saved, some weren't.
DFerron is also right on the subject of passengers and family-
If you're sailing solo, it's your life to waste. Be a Bumfuzzle, and have a ball.
If you're dragging family or non-sailing passengers with you, YOU are responsible for their lives. Don't be reckless and clueless with other people's lives. Make sure you have the skills necessary to sail safely and smartly with passengers and family.
