"As for not using it ... yeah ... I never really gave it much thought as usually considered it something the wind would play havoc with ... apparently not " And that's what your Mum told you!!!!
is a 'PRO-FURL- All our winches are electric
so Vivien can handle reefing very easily.
1) The main is battened as per normal.
2) The sail is cut slightly differently.
3) There is a foil running up the back of the mast that the mains boltrope slides into.
4) This foil pivots following the mainsails luff curve so entry is very good.
5) The foil has 'feeder' rollers and is also flexible on the lower 600mm where the sail initially feeds on.
6) The boom is supported by a fixed vang at a required 89deg to ensure furling is equal across the furling shaft.
7) The boom is substantial, a heavy gybe must be avoided as it will damage the hugely substantial gooseneck.
8) The boom is like a trough or gutter with a sheet drum at its aft end and a tubular shaft running forward to a bearing at the gooseneck end.
9) A sheet runs from that drum to turning blocks bringing it to the Main halyard winch
10) Winches are Harken
As normal all reefing and unfurling is done without pressure on the main same as slab etc.
To raise we head
to wind, haul the halyard
whilst keeping slight hand pressure on the now wrapping furling line. (This line wraps around the furling drum because the shaft that the main is furled on is now turning).
We stop at any point ie 1 to 100% and lock off the furling line with the jammer pulling luff tension as needed. Now if the sail is up we and we need to reduce we simply do the opposite of previous. There is 2 bands on the sail indicating the third marks so you have position to relate to regarding percentages. BUT the choice is yours as to those percentages.
The beauty of the system is a well versed teenager could handle the reefing alone it is so simple, the main carries its horizontal battens so sail shape is very good.
In a storm once stowed/reefed the main cannot self set.
When in port the head
shackle is undone, the head laid into the trough and a cover goes over, this sail cover
is so simple and cheap
