New Mainsail. Part 1

 New mainsail   I did long shoot and decided to use Far east sail loft to design and make my new mainsail. Measurements i did on the boat and I hope I did not make any big mistake I would regret What I changed for new sail: 4 reefs, yes 4 reefs, maybe 4-th is not the thing I would use  in my life, but better to have it than not. 1.2"  shorter on Luff then spec. Max leech set to lift "relaxed" boom 5" higher vs horizontal to be able to set dodger Also i made foot shorter for 3" to accommodate pair of pulleys for outhull. ( i decided to have better control (and shape) over sail surface. Maybe i am wrong, but it is my decision, I selected modern high UV stable cloth Fastnet 7.88 from Challange Sailcloth         4 weeks after I paid deposit and several  e-mails exchange i was told my sail is almost ready to be shipped.                   Waiting next steps...

Days 265-266, ELCI replacement , Mast re-ajustment, Openplotter (AIS/pypilot fighting), Sailing.

 Two days - one work on boat, one to have pleasure on it. Work day Mast adjustments again.  I readjusted  mast again using forward lowers to straight it. It was not easy, but at some moment i realised that top shrouds have BIG effect on this "natural", as I thought, spreaders level bend to port side. However i was able to play with forward lowers and top shrouds to make mast almost straight and without dramatic difference in tension. But sea trial showed the problem is not completely fixed but I have some progress. B ut now I’m starting to think the issue is more related to the top shroud settings. Monday I “confirmed” this with GPT chat ;-) The correct name for my rigging is: Masthead sloop with discontinuous standing rigging with single inline spreaders. Actually, it looks like my mast “virtually” has two spreader levels, but the upper spreader is absent. Instead, intermediate shrouds run from the spreader plates to about 3/4 mast height. That changes the whole mast adj...
