Yes. Tie down everything and PFD on all the time.
I was on recreational rental kayaks a lot of time and never was even close to being flipped, which gave me the ignorance of not leashing my gears and stuffs the first time after I owned a kayak. I was in the bay and thought I wouldn't flip so easily but I flipped twice that day and lost literally everything, over a thousand dollars worth of fishing gears. I was only able to recover sfuffs those float like my slipppers, paddle, tackle box. Hard lesson learned

, it's happens in a blink of an eye

so be safe
