Good to hear you are OK.
Thank goodness for kind and fellow yakers that helped you out.
I watch that show Pacific Warriors and they got all their gear very well strapped down or with lanyards in case the are dumped. I saw an episode where one of them took a swim and he was able to retain all his gear.
I have also soaked 2 phones that were unrecoverable.
The wife bought me waterproof storage for my electronics that she strongly insists that I use every time I go fishing now.
After spending lots of money to replace stuff I now am constantly looking for ways to mitigate risks.
Money and time that are spent worthwhile.
I know that this won't help you replace your stuff, but hopefully ideas will help you in the future.
