Im going to disagree in part with Bear & Phil....
Depends what type of sailing you are doing or intending to do.
Coastal hops or overnighters, then yes you'd have to be reckless not to look at the forecast as well as having a basic understanding of general weather before you cast off the lines.
But if your crossing oceans then you will face heavy weather sooner or later(unless you take the precaution of taking a bucket of sand with you & sticking your head in it when the wind & seas get up!)
I havent been in heavy weather, but I have been reading a fair bit lately
& their are a lot of single-handers that propose 'lying ahull' as their preferred method, they claim good sea boats will all find their comfy positions naturally & roll with the punches so to speak. Obviously the yacht would have to be as watertight as possible. If you do get caught out, the books say its a lot safer to head offshore, than to try closing the land attempting a dangerous entry to port in dubious conditions.
I wouldnt deploy a sea anchor from the bow, I reckon she'll swing around (like at a mooring) putting too much strain on her bow roller etc, not to mention possible rudder damage if she lurches backwards.
BTW, does anyone know the Top Hats "Stability Range" should be a figure around 130 or similar?
