All you rudder guys are missing the problem IMHO.

The FH currently has long rudders with the pintles mounted close together at the top of the rudders.

Get some sideways load and those suckers will twist off.
Without re-engaging the rutter discussion, I would point out that this point has been made several times by several different people. Since everyone seems to agree on this point, there isn't any pot to stir.

I will say at the beginning that what I experience here in San Rafael/Central Marin can be very different from RB and other parts of the area, the land masses make for interesting wind/weather.

What I see in the weather forecast is winds with a northerly element until weekend, as bulbhunter has suggested. It is winds with the southerly element that will mean the most to the anchor outs in RB. Even then the weekend forecast is only for 15mph SW. As I type Point Blunt, Angel Island, often said to be the windiest place on the bay is reporting NW @13.8 mph. I wouldn't expect any wind w/o a southerly element to create too much problems for the average squatter out there.

That said, the continual, if gentle, action from seasonal winds could be the death of FH, death by 1000 wavelets. If a 25k southerly happens, it will be much more dramatic.

I don't have my hand held to listen in on 16, so I can't confirm if HR is calling for assist.

Winds were expected to taper off pretty dramatically today vs say yesterday evening. The next small low pressure system to stir things up near the end of the weekend could generate the next little shift in typical wind patterns and generate a little breeze from the wrong direction. What I've personally experienced over there off Marin over the years is that you can see a good south wind for a short time as pressure systems sort out then have it switch around which case that sort of stuff as most people who have anchored can create lots of issues trying to keep the anchor happy and the boat more or less in the same spot.

Same deal at TI three years living out there it wasn't rare to see a pretty good wind kick up from the south and blow right down Clipper Cove for an hour or two then switch up. Talking enough south breeze for enough time to get a good chop going before it shuts down. The south wind issue does not need to be a long event to create problems.

Some quick study - the waist is about 1/2 the diameter of the hips. If she has a 34" bust, that waist is about 2/3rds of that, or a 22" waist. the hips are twice the diameter of the waist, or 44" waist. 34-22-44

To me, the waist looks reduced, and the thighs expanded.

Is this the Kardashianization of pretty girls? Edit: Kardashian is 36-24-39 - so this gal is even more extreme. I don't buy it. Quite attractive from the bust upwards however.

I think it has gone all pear-shaped...
