in response to the OP's original question about experiences with currents and winds and paddling for your life, I thought that I would share some of my experiences and lessons learned.
Years back an OC 6 team was paddling off the coast out of Channel Islands Harbor. During their paddle, strong offshore Santa Ana winds developed. In their attempt to paddle back to the harbor while battling the building wind and seas, the canoe was swamped and the paddlers were treading in 55 degree F. water with no insulating garments, PFD's or communication device. Two of the very fit paddlers attempted to swim to shore, but unfortunately did not make it. The other four stayed with the canoe and were rescued. All were severely hypothermic and I believe a female paddler was hospitalized. When I went back to work the next day, as a Harbor Patrol officer, I was involved in a search and rescue mission looking for the missing paddlers. I did not find the paddlers, but, I did find the canoe. It was about 6 miles offshore. Pretty much due west from where the canoe swamped about a 1/2 mile from the harbor entrance. The canoe drifted there overnight due to a combination of NE winds and westerly flowing currents. On another occasion, while working as a Charter boat captain, we were summoned by a National Park Ranger to rescue two missing kayakers in a tandem kayak. The couple had planned a trip with another couple to paddle across the Santa Barbara channel to Anacapa island. There was a small craft advisory that day for strong Westerly winds and rough seas. The kayakers planned to depart Channel Islands harbor at 0500. Upon hearing the WX forecast decided to go to breakfast instead. Mind you the ocean conditions quickly deteriorate as the day continues. So, at 0800 they decided to attempt their excursion. They had planned this vacation long in advance and traveled quite a few miles. The more experienced couple made it to the island. We subsequently found the other missing couple in a swamped kayak about two miles downwind of their destination still trying to paddle against the 6'+ seas and 20+ knot winds. They were in very bad shape, hypothermic and exhausted. We were able to rescue them, but lost their kayak and gear. We had paramedics meet us at the dock. Apparently, the woman was in hypovolemic shock and had a miscarriage.
On another occasion, we were returning from Santa Cruz Island after spending the day celebrating my daughter's birthday with her friends.
My wife and I spotted a tendem kayak with a male and female aboard.
They were struggling to paddle upwind against 20 knot winds and 4' - 5' seas. They were about a 1/2 mile off the east end of the island and 4 miles from their place of origin and destination in an area called windy lane. As with the other couple mentioned above, they were not making any progress toward there destinations. actually losing ground. Anyway, we were able to rescue them and their rented kayak and gear. These were inexperienced tourist from Korea that were warned not to paddle downwind and outside of the protected cove. After delivering the kayakers to the beach, We were on our way home only to discover, via the VHF radio, that there were two more kayakers missing. Apparently they left the beach with the other couple. They did not fare so well. The couple was dashed against the rocks about a mile down the coast. The male survived. The female was eventually rescued by the Coast Guard and airlifted to the hospital where she died.
So, some of the lessons learned here are pretty obvious.
Be prepared, know your capabilities. Have proper equipment (safety equipment) for your outing. Heed WX advisories and forecast, although I realize we as surfski paddlers do exactly the opposite.
But most of all, in my opinion, don't try to defy mother nature.
If she says "Hey dude I'm not going to let get to where you want to go", find a new destination and go the direction that works. It may be terribly inconvenient, but. chances of survival are greatly increased.
For example you may be able to paddle down wind to an offshore oil platform or a distant lee shore. Possibly look for a protected cove to hold up in etc.
Anyhow, hope some find this a worthwhile read.
