Wow! Another great vid. Thanks!
One of the comments on that video said something about how that flow in/out is just a normal day at Deception Pass up in WA. That's great, but I wanted to point out that this was not exactly a low/high tide issue. These waters were going in and out, seemingly, at their whim.
Like I said in MdR, the flow alternated many times during the low to high tide period...so there just wasn't anything some of these mariners could do other than listen to the radio and hope somebody was reporting conditions at the harbor entrance constantly, or just stay out at sea.

|YeahJohn||We have had some crazy 'seiches' as well here in Dana Point. I would say around four or five a day sense Friday. I have watched many boat almost get wrecked, and there was even a whirlpool at the harbor mouth. Check out this video of a motor yacht almost getting thrashed entering the harbor Friday evening.

|dnickers||Wow! Great video! It is really something to see those buoys in the main channel being pushed around like that. It's a nice reminder of just how powerful water and the ocean is.|

FYI, I found this on youtube today to give some color to what MdR looked like on Friday. I was travelling to Florida that day but our marina manager did a great job at keeping us posted via e-mail throughout the day.

|SlowButSteady||For comparison, here are traces of the data from three DART buoys; one near Japan, one near Hawaii, and the one off SoCal I posted a few minutes ago:|

I was at my boat yesterday, about 24 hours after the major tsunami effects. For the first time in three years I could see a visible outflow current, and this being in the 5-7 knot category. I spoke with my dock-mate who lives aboard and he said that on Friday there was in and outflow currents of up to 10 knots.
This was in Channel Islands harbor and I think it weathered the tsnami well. Too bad about the other harbors, not to mention Japan.
Take care, Bill

The estimated surge in Ventura Harbor was 3-6'. My dock neighbor told me the surge hit at low tide but our dock was still about 1-2' from topping over the pylons. All day yesterday there was a significant current that would reverse direction every few minutes. My knot meter recorded a max speed of 7.5knots...tied up in the slip and they tell me it was much faster on Friday. The dock captain showed me a video of a small rib at full throttle and only moving about 2knots in our fairway. The whole thing was pretty wild and scary.
When I leave the boat I always lock the wheel with the rudder at 0deg. When I got to the boat yesterday the wheel and rudder were over hard against the locks. The boat was pushing so hard against the dock lines that one of the bow dock cleats was starting to pull loose.

Here's the trace of the data from a DART buoy off the SoCal coast (right about at the US/Mexican boarder).
Note that the trace should be a nice, smooth representation of the tidal height, but that starting at Friday's LLW things start getting decidedly un-smooth and that it has stayed that way since.

|dnickers||I'm kind of surprised I haven't seen any more local news regarding the behavior of the ocean down here in southern California.|
