As SRM says, it depends on the wind..... and in your case, the sea conditions, tide/chop etc
I suggest you have a Plan B if the timing does not work when you are out on the water.
Last summer, in a moment of madness, I called my lovely wife and suggested we do the Port o' Call Long Distance Challenge.
(Go to Google maps, and look up Ottawa, Ontario, Canada, and go to the 18 mile section of the river upstream of the rapids... so from the head of the rapids up to Port o' Call Marina) and back.
12.8 nautical miles upriver and another 12.8 back, as the seagull flies, (not counting tacking/gybing).
The weather forecast said 10 Knots from the NE, which is good wind and flat water, so on my H18SX with spin, I figured 1 hour up and 90 minutes back.
We probably left the dock an hour too late... which meant that 1/2 mile short of the turnaround at 5.30 pm, the wind started dying.
We made Port O' Call, turned, and 1/2 an hour later, with the sun going down, we started to drift... and I have no navigation lights. Yikes!
Move to Plan B...out with the paddles....and we paddled about 3 miles to Pinney's Point, when the NE breeze picked up again.
Sailing at night is very peaceful, and lucky I know the river well. We could see the other sailboats by their lights, so we managed to stay clear.
Just to be safe, I would take a picture with my waterproof camera, which meant the flash would fire, then the others could see me.
I now have a flashlight in my emergency pack.
Sailing back into the dock at 10.30 pm, we were surprised to see two keelboats heading upriver for the weekend.
They were just as surprised to see us coming in.
We were in bed in time to watch the last part of the 11 pm news.
It always helps to have a Plan B.
BTW, ours was the fastest time in 2015 for a cat, so we did win an Inter-Club award for our late night adventure.
Good luck with yours.
