Full keel vs fin keel for offshore?

sorry I forgot to say transceiver
the link says without ssb transceiver

I was a big Robin Lee Graham fan back in the day is how I ended up with a Bristol 27 (and the $2,000 price tag) after 15 years of racing high tech beach cats with high aspect mains, rudders, daggers boards, technora sails, spinnaker, etc

Plus all the cruisers at our apartment (Pensacola, FL mid 1990's) on the water (we had a dock, $50.00 slip for residents!) mostly were all total characters and most all had old beat to hell full keel boats that still sailed just fine.......with their ancient sails

Interesting! Curious- what about Robin Lee Graham made you get a Bristol 27? He had a Lapworth 24 and Luders 33- I guess your boat splits the difference?

That’s a concern for us as well... plus crime and spiraling costs associated with it.

That being said those thin vacuum infused hulls don’t lend themselves well to getting off hard groundings, or beaches, and surviving with sail away damage.

Great videos.

If that's what a sea squall is and those are the common weather patterns I'll see. Lasting an hour to a few hours or a day. That's not nearly as intimidating as what I was imagining. Here I'm picturing the wrath of God with 30 foot waves coming down on you. I'm guessing that's less of a squall and more of a tropical storm.

As for hurricanes I am going to try to plan my voyage as best I can dodging the seasons obviously. In the unfortunate situation one forms beneath me I guess it's heave to and hope it passes under me or above me. If I end up in one I guess I'll be mighty screwed and best do what I can until I can't any longer. Let's pray that doesn't happen.

I think after the length of discussion on here about boats, gear, equipment, mental and physical preparation. The boat at least will be as well prepared as I can make her. The rest will come down to a bit of luck.

I still haven't decided what direction I'll go on getting weather reports. SSB, radio, sat, etc. Seems to be a few options. I have a fundamental understanding of weather patterns and formation. I'm sure given a little instruction I can learn to look at the clouds and get a general idea of what to expect. Whichever route I go I'll have some form of weather report grabbing even if it's the cheapest form. I'll make sure to know how to use it prior to setting out. I believe there's a book and some good articles online on how to learn to read those weather reports and gribs. Looking at it off hand and without context and the small images I can't make much out. Again something I'll need to familiarize myself with prior to the voyage.

I was going to lug a few tools and some of what I consider essential materials. I think I mentioned this in my equipment thread. Some minor repair materials in the event a hole gets punctured in the boat or etc. I've been watching a few videos on at sea repairs. A transom rudder looks difficult to repair in that it's fully submerged. I'm unsure how one would fix that at sea and if it broke off I don't think you're getting it back. Hence I was thinking of carrying a lightweight board of some sort I could fabricate a stern hanging rudder from. Better than nothing. I guess it would make sense to have something to fabricate a ghetto tiller out of. But the likeliness a good condition tiller will break seems slim. Just my thoughts anyways.

Here's a link to a few of the best books on weather and storm survival - and they're free.

you beat me to it I have those in my library and was looking for the link

Your second example does not look like a grib file to me. It is just a different display of a MSL analysis. A typical grib file will show an area map with wind speed and direction as a minimum, displayed on a grid whose fineness you specify when requesting it. Looks nothing like your example. They can typically be ordered up for any area worldwide and provide forecast conditions for some days in the future.

Jim they both show wind speed and wind direction as per the wind barbs on both displays.

yep that's the page but I just did a screen grab sorry should have posted links as well I usually do I'm just asleep at the chart table again

[Jim Cate]

OK, if I look closer I can see wind arrows superimposed on the MSL chart. But, I still don't think the example chart is like what one downloads when at sea. It sure isn't like the ones that I get via Winlink and saildocs, having far more detail, and requiring much larger file size to convey that detail, something not amenable over HF links.

Perhaps I'm missing something here... if there is a better non-internet based method, please explain it.

Jim

PS I'd post a screen shot of a typical winlink grib, but it keeps coming up over 6 Mb, and I don't know how to shrink it to an acceptable size.

true they are not as detailed as winlink is however even basic black and white you get what is needed to do a forecast of what you should expect within the next few days where ever you are. That and the mark1 eyeball.

A smaller downloadable via sat phone would be
PassageWeather - Sailing Weather - Marine Weather Forecasts for Sailors and Adventurers

From the linked page:

It has been designed to superimpose on a chart several weather data like faxes and GRIB files,

If you look closely at the chart it has several maps superimposed: There is a surface analysis fax for the north pacific in red, and also for the central pacific in pink, there is also the 500mb analysis fax in light blue, and the grib data in dark blue.
