Man, if you keep-short tacking someone is gonna get p!ssed!

You don't just get up one day and go run a marathon, or grab a bike and ride 100km through traffic for the first ride. So you don't just strap in, launch, and head out (to sea) to see how far you can go.
Let's face it, ideal conditions for most spots are cross-on shore winds, so you're going to be going offshore on one tack to a certain extent.
Once you get some confidence with body dragging and transitions you will find you go a little bit further each time.
Most guys I see don't like to go more than a couple of hundred metres out, and there's no real need to. (As long as you're not short-tacking! Lol)
Some seem to love it and go miles out. There is a beautiful peacefulness the further out you go.
But it certainly ups the risk. But you do know they call this an EXTREME sport, right?
If you do want to start going further out as your confidence builds, keep a few things in mind.
You need to be able to body drag, and you need to be able to confidently transition.
Golden Rule:
Don't go further than you can swim (dog paddle, whatever to move along) it may take a while to get in but it should be within your capabilities.
Pick your conditions.
A wind direction that, if worse comes to worst, will take you back towards shore.
Don't go so far that you'd go round the headland, point whatever, and float 100km to next landfall.
Check the tide and current directions, they can take you where you don't want to go very quickly.
Make sure someone knows you're going out. Preferably someone on the beach, but you need to be missed before the next day.
And one last time, it's EXTREME! HTFU!
Go BIG
Go HARD
Go DEEP
And remember, we all float.
