sounds great ,, but what do you do when you want to run along the face of a wave , i cant imagine how it can do that ,, but i know little of such electrikery

You do ofc need to watch that you don't have persistent winds shifts and are sailing the wrong way.
thats alright ,, i seem to spend half my life going round in circles anyway !!

Re: La Vagabonde's crossing

help ,,,, on predictwind what is the current page ,,is it PWG,, PWE , ECMWF or GFS,,, because they are all a bit different ,, ? is it yesterday , today , tomorrow or what .. maybe not easy answere , i can see the different symbols etc but the weather systems are in different places , that is what is confusing me

Re: La Vagabonde's crossing

big change , now ESE ,, guess they are far enough north to get the bottom of the Labrador low and that might get them enough easting to get onto that northern low

They are different models. Different predictions of what will happen in the future.

Are you are referring to the predictwind display with the boat's position on the SLV website? There is a white "layers" button in the top right corner. That opens up a menu where you can select the model and the forecast display. There is no time slider, so it is likely to be "now" or at least "today".

well, in my last routing they were scheduled for a wind shift and to turn east 35 minutes ago

hopefully, the wind shift will continue around and they will soon be able to go due east. They don't want to put much southing in.

next weather model update is in a hour and 40 minutes.

it is a predict , but i dont know if it from SLV , it is from a link that " atoll " put up a few days ago ,, there is no menu on the right but one on the left which puts up 4 options , some times quite different some times ( as now ) very similar ,, i just want to now which one is the present ,, i have another site which i also use and can usually work between them to get the one on predict , but it is a hassle ,,,thank you

Re: La Vagabonde's crossing

GFS updates every 6 hours 06:15,12:15,18:15,00:15

ECMWF 0.1 updates every 12h 07:15 and 19:15

the two predict wind 'value-added models' PWG and PWE are based off the GFS and ECMWF output and according to predict wind site "Each forecast (PWG, PWE, GFS & ECMWF) is updated twice a day, every 12 hours." so they apparently miss two of the gfs updates.

My understanding is that more sophisticated APs use the paddle wheel sensor to detect unusual increases in STW when running downwind and then turn the helm to steer down a wave at an angle. Sounds rather incredible I know, but when you think about it how else could Vendee Globe racers (for e.g.) leave the helm during frequent periods of big following seas in the S. ocean?

I am a vocal spokesperson of doing as you please in life according to the sentiment: Enjoy yourself and be kind. But this implies agency, something an infant does NOT have. As long as it is consensual adults, knock yourselves out, literally if you must. Taking a child into a fairly uncertain situation is not good seamanship, or parenting. They should absolutely have left the kid with the grandparents and done the sail.
You don't think the child also has the right to be with, and experience the life it's parents enjoy.

Their tracker is set to send update hourly.

They initially were reporting a couple of minutes after each hour (the result of exactly when they initially turned it on).

Then after they turned off all of their electronics during a period of heavy lightning it changed to 10 minutes before the hour. (So they turned it on at HH:50)

Actually modern autopilots like the b&g h5000 also have the ability to
use data from motion sensors which measure roll and pitch. Using this sensors the pilot 'feels' the waves and combined with the wind sensor
it is able to steer the boat even in rough and confused seas...
