Replaced the Blocks with a low friction cascade

on the boom vang

I am always looking at better ways to optimize things and seeing as I had some spare low friction rings I replaced the blocks on the boom vang with a cascade system made of the low friction rings it is lighter, simpler, neater and has super mechanical advantage.The 3 lowfriction rings make a theoretical mechanical advantage 0f 8:1 but with the friction from the rings it is probably more like 6:1, maybe more because I am using slick dyneema. It could even be possible that the the block at the mast base may even make it a 12:1 or a 16:1 system ???? all I know is that it is real easy to add huge downward force  -  feel free to clarify if you know.

The Twin Mainsheets may make a boom vang redundant but the mainsheets and the boom vang make it really easy to trim the mainsail shape in my opinion.

A round the world non stop record challenge

 in a modified 5.8m Class Globe 

Alessio Campriani is busy with his challenge at the smallest boat around the world via the great capes record. He is doing it in a modified 580 and has added a hard dodger, a crash bulkhead in the bow - Like the bulkhead in the Setka A, a larger stronger mast section, Twin rudders, Hydraulic autopilot , an escape hatch in the hullside near the bow and a stainless bowsprit amongst other changes.

here are some pictures of his boat

Wishing him fair winds and a all the best on his adventure - break the record!  Go For It!

 Raspberry Pi Navigation System

I have been busy setting setting up a navigation system that runs on a raspberryPi computer, a 10 inch screen and a USB GPSmouse -  that combines charts,  grib files as an overlay and ais data wirelessly sent from my Onwa ks200+ - it does weather routing as well - using wind instruments I could even get their data via SignalK. I am busy working out Polars as well, at the moment I am using polars from a Muscadet as I have not yet created a custom polar file.

here are the screenshots from the system

Please visit the blog again to see how the system will be installed on Cagarro and also please visit the youtube channel and register because I will be making videos showing it in use and if there is enough interest  maybe some videos with  hardware options, chart and software installs as well
