I also rowed for many years.
I woke up daily at 4 am to avoid the wear and tear of the hot sun.
It was a great experience!
The precaution I would recommend to you is to ALWAYS, regardless of your self-confidence, wear a life jacket.
There was a day, after an hour and a half of rowing, I fell out of the boat and didn't even have the strength to get back up.
I only survived because a fishing boat was passing by.
