Experience
Michael,It is probably a good thing you retreated. Turning south at the R8 bouy in those conditions could have exposed you to conditions that would be much worse. If you look at your chart there are shallow waters south of the bouy line. In particular there are shallows south west of R8. Those shallows have the ability to shorten the wave period and build them higher. On a day such as you are describing you would want to go all the way to R2 before thinking about turning south. My opinion. In fact, conditions would have to be pretty good for me to shortcut those shallows. I've seen 11 feet in that area when the regular pattern was 5-6' outside.Same can be said for the Bonita channel. When the surf is high, it is safer to go farther out prior to turning north (outside the shallows). I have captained on one trip with an instructor on board where entering the shallows was automatic failure of the class. We went north on that trip and saw winds of over 40 knots sustained and 11' seas later that afternoon. We were in a 42' boat.Going all the way to Santa Cruz will require overnight. I'm presuming that you know that. I suspect you might make it if you left in the middle of the night or late at night and still have light when you get there the next day. This time of year, I would not count on the weather being acceptable for the trip. Frankly, the decision should be made anytime of year based on those conditions.You can go online and find wind/wave predictions for some days in advance of a planned trip. It is not a round trip in one weekend, unless you are into marathon sailing. I am assuming you are going one way on that weekend.That all said, I'm concerned that you have not had coastal navigation experience. I know it sounds like just keeping the coast to the left should do the trick, but that is not necessarily going to be how it plays out. Fog, or lowered visibilty might prevent you from navigating using coastal landmarks. A good understanding of charts, and ded reckoning is imperitive. Radar never hurts in those conditions either.If you have to put in somewhere along the way, such as half moon bay, you will want to understand the chart and lights very well, as this may occur at night. And there are a few ways in there you don't want to try.Finding someone with some experience to go along is a very very good idea. Look for someone who has done the trip before if you can. It can be a great learning expereince.I would have to know a lot more about your boat before I would volunteer to go. Such as safety equipment (jack lines, epirb, liferaft, etc.), condition of the boat and equipment, shoal draft or deep, etc., radar, and given your experience, you would not be captain. Hope this helps a little. Stay out of those shallows!Dan Jonas (S/V Feije II)
