What do you want to know? I completely agree with you that having the controls centered makes more sense. The sequence for timing is always as follows: -release the tweaker -release the leeward traveler control -adjust the traveler with the windward control -reset the leeward control -adjust the main sheet course adjust as much as possible (I rarely if ever use the winch). -do the final trimming with the tweaker. Generally this is whatever is needed to center the boom. -if I can't get the boom centered then I'll release the tweaker again and raise the traveler more. Then retry centering with the tweaker. The only thing I've been interested in doing to upgrade my system is get a windward sheeting car. This system automatically releases the leeward traveler control in preps for the adjustment of the windward control.

As it turns out you are the first to voice concern. Are you worried about the pelican hook coming open? I can't recall exactly but I believe the hook is rated at 5000 lbs SWL. The scarier part of the setup is the small diameter of the hardware associated with the fine control block and tackle. They are rated appropriately but still appear small for being a single point vulnerability.

@@muckleyj Hi, just don’t like to see it all fly loose soo easily. There have been multiple deaths with main sheet control failures. One on an associate boat where of all things a preventer failed the block assembly fatally struck. A suggestion, just have a good size and condition shackle that can be undone, may take an extra minute but. Cheers S

Thanks

The cheap kind from China. I got 'em on ebay. They work as described so I like them. Two of the 100w panels tied to 2 genasun MPPT boost controllers. I get ~12 amps at peak sun. I can plan on about 75A-hr per day.

@@muckleyj thanks for the reply!

Traveller is made by Harken circa 1989

@@muckleyj I am looking for a setup like that, mine is adjusted from sides and it is a pain in heavy air.

@@MrMedicAdnan, first and foremost release the main sheet just before you move the traveller. It will unload the bearings in the traveller and make moving it much easier. Generally, I run the traveller to the low side just before the tack, once down the helmsman commences the tack and I've moved to release the jib sheet, then take in the other. One the jib is set move back to the main sheet and in my case usually just harden up on the tweaker to center the boom - no traveller adjustments needed. If they are then ease the tweaker and take in the traveller.

I'm not sure exactly what to explain. Take a look at this explanation and come back to let me know if you still have questions. science.howstuffworks.com/transport/engines-equipment/pulley.htm

@@muckleyj hi, I am grateful for this information, so its a pulley system to make moving the boom easier?

@@michaelsrowland yes basically. Without the boom controls then the wind would just push on the sail and the boom would swing away. The sail would act like a flag. I'll see if I can find some sailing 101 videos or other links for you.

@@michaelsrowland around the 9 minute mark you can see an elementary demonstration of boom controls on a very small boat. The sails on this boat might total 50 sf. As the sail size increases the power is cubed. So a 100 sf sail would have 8 times the power of a 50 sf sail. My sails are over 300 sf. 6 times the size in the video. This means my sail is "6 cubed" more powerful. Or (6^3=216) ~200 times more powerful. Without a mechanical advantage in the boom control, it would require superhuman strength to control or adjust the boom. kzfaq.info/get/bejne/pLtgh5uV3pbVpas.html
