Re: C-Map vs Navionics charts

Alan Leslie
 

It seems it very much depends on where you are.
In the South Pacific we have found C-Map to be very good. Navionics is very good in SOME places but definitely not all.
In the Yasawa islands, Fiji,  Navionics showed reefs where there aren't any and didn't show some reefs that are there. It also didn't show passages which are marked with buoys that have been there for years.
In New Caledonia however Navionics charts seemed very accurate and the bottom contours particularly useful (is that because NC is French?)
We have both C-Map and Navionics in Time Zero, Navionics also in the cockpit B&G plotter with forward scan (not very useful), C-Map in the Furuno NavNet II at the chart table and the cockpit and OpenCPN with GE2KAP satellite photos on the PC at the chart table and repeater tablet in the cockpit, which is very useful to display along side a chart to see reefs and shoals that sometimes aren't on the charts.  
Can't be too careful!

Hi Joerg,

I use C-map on my board PC and Navionics on my B&G plotter. I agree with your findings. For this reason I bought another navigating app on my PC that allows me to copy (within this app) the Navionics sd-card onto the hard disk of the PC. Don't try to copy without this app; little chance to succeed and the risk of loosing the functionality of the Navioncs sd-card.as well. The app I bought is called 'Tiki'. This is the website: http://www.tiki-navigator.com/English/default.htm

I use this app now during two seasons and I am quite satisfied to have the Navioncs chart not only on my plotter but also on my board PC.

Best regards,

Willem Kroes

Here is a source for the contactor: https://www.eibmarkt.com/cgi-bin/eibmarkt.storefront/5d3498c9007021c62746ac1e04020600/Product/View/NS0742502

 

I believe the original was rated 25A – I may be wrong about this.

 

Also, consider Amel as a part source on this. If the old part is no longer available perhaps they can suggest a replacement.

The full description of the original contactor is LC1-D25008-M7.  It is discontinued.  I have ordered a used one on ebay, so I could eventually do a like for like swap, but I have been unable to find a good substitute new model.  I would much prefer to use a new product.  Does anyone know what product would meet the specification of the original (including rated for 40A continuous current etc.)

Craig, based on your advice, I am looking for a place where I can get the rewinding of the stator or rotor done.  It was really great to read that it is not necessary to remove the generator.  I will see around Sardinia, or points West of here.  Much appreciated!

I forgot to mention that the alignment looks spot on, there is no side wear on the belts. Just the bottom teeth coming off. A damned mess in the engine room of course but no harm done.

Re: C-Map vs Navionics charts

 

I am sure that you all know this about Vector Charts: There is a huge amount of information embedded in these chart files. Some chart plotting programs allow you to select what will be displayed. If you are a user of OpenCPN, you have probably noticed about 100 display options. The same Vector chart on Other Chart plotting programs offer very few options.

Re: Spade Anchor

Eamonn Washington
 

Hi

I have 2 spades, S140, the still unused and bubble wrapped spare from Ian and Judy plus the one I use daily.  2 years ago I anchored on Ios in F10 for a couple of days and It held while boats dragged all around me.  In the straits of Messina, with a 4 knot current, we anchored and endured some 180 degree current shifts, and again it held perfectly.

If I was buying new I would go for the S160 probably, although with the S140 I always slept well.  I was impressed by the Ultra in boat shows.  I believe the newer Rocnas are good, but not for me.

Re: Hot water pressure

 

David,

The simple answer is air is getting into the hot system at a point where the air entry is not "wet."

I'll take a wild guess: 

Here are 3 things to look at, in order of probability:
There is some trapped air in the hot water tank and eventually will stop
The electric thermostat is not turning OFF the heating element, allowing boiling inside the tank.
If the pressure relief valve is located above the tank waterline, it may be leaking, allowing air to pass into the tank.

Re: Panama Crime on the Caribe Side

Thomas Kleman
 

I have to admit, we have been cruising in this area the past 6 months and the recent uptick in crime has me spooked. The fact that there seems to be no police response is more than alarming. When added to the recent attacks north of San Andres off Nicaragua it paints a grim picture. I'm now considering pushing forward my Canal transit since it's easier than mounting an 88 mm Flak gun on a Super Maramu.

On the Navionics charts, on the other hand, I often have significant depth soundings and contours and rocks not shown on C map. And there are other inaccuracies as well. Just now on my way south to Carthagena I passed a fish farm 5 miles from land that is not on my C map chart but is shown on Navionics. And I just updated the C map ( but not Navionics).

Is this experience typical for C map in other regions of the world as well? I’m thinking seriously about buying Navionics for the Atlantic. Can you mix C map and Navionics on the same plotter?

Re: Auto pilot for a Santorin 46

Thanks to those who responded with sensible advice

With time on our hands we bit the bullet first pulling the motor apart and discovered that the small springs holding the brushes in place needed a tweak so they applied more pressure to their task

Then we pulled the arm apart including the small ball bearings gave all a good clean then applied lithium grease. Delicate and slow work to get the ball bearings in place. (Same system as the steering in a David brown tractor)

Whole job took about 6 hours but the auto pilot is working again......whew!!!

Re: Panama Crime on the Caribe Side

In 2017 I found Portobelo to be poor but safe.  There is an interesting history there in that it was the staging port for the Spanish galleons  carrying gold and silver back to Europe.  It was heavily fortified although only one of the four forts has been excavated for viewing.

The sail loft there did some good canvas work for me at a very reasonable price.

If you happen to be cruising Eastern Panama toward the end of October, consider taking in the festival of El Cristina Negro (the Black Christ) at Portobelo, it is quite a spectacle.

I guess it would be wise to check out the crime situation first, but it would be a shame to miss it.

Linton Bay was also poor but safe in 2017, but there wasn’t anything there I would go back to see, especially in view of recent crime.

This is also true. One of the vessel’s EPRIB was found but there was no sign of wreckage.

 

The crime on the Caribe side of Panama this year has now reach an alarming level. Besides the recent armed robberies, there has be acts of piracy and murder. This includes only the crimes reported on CSSN. The regular crimes against tourist in Colon go mostly unreported and uninvestigated.

 

Thankfully the Pacific side of Panama and Panama City is a completely different story. It hard to believe this is the same country.

Heads up to owners in the Panama area on the Caribbean side. There has been a serious rash of armed robberies between Shelter Bay Marina and the San Blas Islands. Linton Bay is especially volatile at this time. Several boats anchored in various bays were boarded by armed thieves. Details of the robberies can be found on CSSN https://safetyandsecuritynet.org/. At this point no arrest have been made and the robberies are expected to continue.
