Re: AMEL orange boot stripe

Actually, while we are on the subject of colour, using AWLGRIP for example, what is the recommended colour match for, the brown thin stripes on the deck, the light tan imitation teak on the deck (I think Desert Sand), the off white/light cream used about the external and cock pit surrounds, the white used on the hull?

Thank you

Hello Gang,

I fully back Ken in his OpenCPN support and use.

It is done brilliantly by sailors and it is FREE!  Like most things, there is a learning curve to it.

Google overlays is not difficult to read, and is sometimes the only option for a map.  In some places the maps are a 100 meters off.  Take a look at the entrance to Maupiha'a in the French Polynesia.  The entrance is a 30 meter wide channel, and only one place to get in and out.  Most maps are 100 meters off.  You can see the entrance clearly on google maps, and all the shallow areas in the middle of the atoll once inside.  It's nice having a moving map showing the entrance.  For this entrance the Navionics Maps were correct, but at the time I didn't have the google overlay, and I didn't know which map was correct. I had several maps, but which is correct?  If I had the google overlays then I wouldn't have had to wait 4 hours outside until someone informed me over VHF which map was correct.  

The wind was 35kts and kind of rough when we entered Maupiha'a.  Google Maps are just another tool that sailors can use to make sailing around the world a MUCH safer proposition.  Many boats that ended up on a reef could have been saved with a quick look at a google map while doing the planning.  And, please don't think it's like reading tea leaves, because it's more like a walk in the park.

I also use a Mac for OpenCPN.  I have never made a .kap file, I just go on line and search for .kap maps for the area I will be going.  And, I have found most of the maps I was looking for.  Currently I have 9GB of maps in my OpenCPN Folder.  And I have 3 or 4 maps for each area.

One more thing about OpenCPN.  It's got a great Climatology tool.  Shows all the paths of hurricanes, and typhoons over the past 30 years, and how strong and location each day of the year.  It also shows the normal winds for each day of the year,  which is great for planning ocean crossings!  It also shows the currents, but have found this feature to be useless.   I do all my crossing planning using these tools on OpenCPN.  I encourage everyone to do a deep dive into the capabilities of this very helpful tool.

Re: AMEL orange boot stripe

Ken Powers SV Aquarius
 

I painted the boot stripe red, and just had it done in GelCoat.  I am looking forward to seeing the longevity of GelCoat vs paint.  The paint lasted about 2.5 years under the stern, but the bow still was looking great.  Not sure what paint was used when I had it painted in Trinidad 2.5 years ago.  Probably should have painted it the stock Orange like you are doing, but just liked red.  

Regarding the photo from Jose....  They always look beautiful splash day!  But, you don't know how good a job was done until 6 months later.  Or, unless you watch the workers every second, or just do it yourself. But, even then you probably will find the problems in 6 months.

Hi Porter
The latest version of Ge2kap is now called Sat2chart as it provides access to a number of different satellite image sources and produces output files in other formats besides kap. I have setup a windows virtual machine on my Mac in parallel with MacOS, this allows me to run any windows only apps that I need. I am using Vmware Fusion and it is efficient, easy to setup and relatively inexpensive. I recently created imagery for New Caledonia and Vanuatu on this machine and it worked quite well.

Re: Anchor roller

Craig Briggs
 

Hi Bill, I should think that sawing will certainly work, especially since the shaft is welded so it won't spin on you. SawzAll with a metal blade may be easier than a sabre saw, but either should do. Seems, though, that you'll still have the issue of drilling out the weldment.
Also, I suspect the original installation was welded purposely so all of the frictional forces were distributed across the full width of the roller's internal bushing. Replacing with a bolt will likely allow the shaft (new bolt) to turn rather than just the roller/bushing which may cause undue wear at both ends where there's a point load against the support brackets. With some salt crud build up I could see the ends of the bolt wearing through in (relatively) short order. You may want to weld the new bolt in place (just like the Captain did! :-) .

Anchor roller

william reynolds
 

It's time to replace my anchor roller. There have been a few inquires in the past but no suggestions.
The shaft is welded on both sides. Poor  installation.
The only  remedy I can see is to sabre saw on either side of the roller and then drill new holes for a bolt in installation..
The previous hole that was welded will be much too hard to drill out.
Anyone got any other ideas?

We’re a Mac family. To download google map or bing map overlays, previously we needed a windows machine for creation of Kap files. Ge2kap I believe was the “program.”  Www.Venturefurther.com allows creation of kap files for Mac users.  FYI for others. Does anyone know of any additional methods for Mac only folks?  
And what a help opencpn and the google maps have been!

For the question.  I set the alarm on the Echo Pilot for 5 meters.  And though it's annoying, it works.  If I am entering a marina, and it's 4 meters deep for a 100m the alarm will constantly beep.  Someone might say, "turn it off", but it's my reminder to keep my scan going.  The scan is just like flying a plane, you're constantly looking for an display/device/person that may not giving you correct information.  And, another good thing about having a FLS.  Most of us are carrying spares if something goes wrong.  How important is your depth sounder?  I would say VERY.  But, many of the SM's are getting older, and everything is not always working 100%.  If your depth sounder goes out, it's really nice to have a back up...  And the FLS is also my backup depth sounder...

When: Saturday, 10 October 2020, 20:00 to 21:00, (GMT+00:00) UTC

Where:Internet ZOOM

An RSVP is requested. Click here to RSVP

Organizer: Bill Rouse brouse@... +18323804970

Description:

Jimmy Cornell has influenced the contemporary cruising scene more than any other sailor. An accomplished sailor, public speaker and author, he has sailed over 200,000 miles in all oceans of the world including three circumnavigations as well as voyages to Antarctica and the Northwest Passage.

Thousands of sailors have fulfilled their dream of blue water cruising with the help of Jimmy Cornell’s books, among them the international bestseller World Cruising Routes. Now in its 8th edition, and with over 200,000 copies sold to date, this is one of the best selling nautical publications in the world.

As the founder of the highly successful ARC transatlantic rally, Jimmy Cornell is credited with having devised the offshore cruising rally concept. In the last four decades, Jimmy Cornell has organized 38 transatlantic rallies, five round the world rallies, and one round the world race, with over 3,000 boats and 15,000 sailors having participated in his sailing events.

From my perspective, the first Jimmy Cornell seminar that Judy and I attended was after we had sailed most of the world and had over 20 years of sailing experience. We learned a lot!

We are very pleased that Jimmy has taken time out of his very busy schedule to give a special ZOOM presentation to the Amel Yacht Owners Group. I encourage you to RSVP soon for this meeting.

I’m going to guess you haven’t used google map overlays. That’s OK.
We have, and they are very helpful.
In fact, openCPN, with google overlays is used by quite a few cruisers in the South Pacific, where charts have questionable accuracy. Some charts are 1/2 nautical mile off.

We used OpenCPN extensively on our previous boat. Even though there are no depth numbers on a google overlay, it is easy to see depth differences in the color of the water, and in many instances, a google map overlay helped immensely to avoid shallows when entering an anchorage, sometimes even better than a standard chart.
The last OpenCPN update made their free software a major contender to most chartplotters. We appreciate the efforts of the developers and would make a minor donation to them every year we used the app. It’s a great piece of kit, and does handle AIS target information better than many chartplotters. Weather overlays and Radar overlays are seamless, and it also has split screen capabilities.

Danny,

I also could not believe that the reefs/bommies came straight up from 50M. Amazing!  And, I would be moving along at 6kts and was able to see them 80 meters in front of me.  80 meters gives me plenty of time to stop Aquarius.

Best,

Ken
