Sorry to hear this.. On top of my sober nightmare launches (6 footers at Deer Creek in Malibu - Ended up with me driving to Urgent Care in Riverside cause I jacked my Knee) I have lost plenty of stuff out there while drinking also

It hurts a lot to thank about but like all the others here are saying.. Let it be a lesson and not deter you.. Get back up on that high horse buddy and catch a big fish off that kayak!
(P.S. swell interval was 3-4 feet at & seconds the past couple days, that's far too short for my liking as you experienced, 3-4 is not bad but at every 5-7 seconds..) Just make sure to do due diligence researching conditions beforehand
