What sails for SF 50

Rupert Murdoch's son lost a finger to a sheet by getting it caught between the sheet and a sheet winch on a big racing boat. A balanced rig is what makes it possible for me to build a boat with 2-1200 sq. foot sails with no qualms. I won't even install sheet winches, between the 7 to 1 purchase and the sail overlap that reduces sheet loads.

Another thing to note is that the less of a bend that the sheet makes in the block the better. A bend that turns the sheet 180 degrees means that the load the block and the deck are experiencing twice the load of the sheet often times for very little reason.

I have typically seen it in the context of huge light air gennys, because they are so long and because the winches aren't right aft. It certainly does increase the already large loads of marconi sails when this is done.

I have single line reefing on my much smaller cat, and like it, because the reefing lines leed back to the cockpit, and when properly rigged and maintained, allow me to reef the main without leaving the cockpit, except to tie up the big bag of sail resulting from any but a roller reefing system. It means you would have to leave the helm to your wife while you go up to secure the loose folds on the boom.
I think you should sacrifice a (very) little sail efficiency and go back to in-boom reefing and furling. Go big, go powered and go redundant. Thats a lot of horse power up there!

We should talk about storm sails, that can be rigged on very short notice.

Can you expand on this please?

why not go for one sail for reaching and running : The parasailor.

It combines 2 sails in one ( a gennaker and a spinnaker ).

It can be used between 70 and 180 degrees to the wind.

More and more bluewater cruisers use this sail.

According to Bobby Shenk, Germany's most famous sailor ( who uses this sail on his Privilege 465 ) it's a must have on any yacht.

During a 15 day trip from Cape Verde to Trinidad he kept it flying non stop ( day and night ) for 14 days.

The opening in the sail ensures that air flows over the wing and it functions as a pressure-relief valve.
The lift of the wing relieves the pressure on the bow considerably and reduces rolling, yawing and pitching. Despite higher speeds, this allows much more balanced steering and greater sailing comfort.

I have used parasailors in the past and they work well in between 120 to 180 degrees but 90 as they tell you is just not possible .
To expensive for such a gimmick.

My 2 cent worth.

Thanks for the suggestion.

We had just read a praising review of the same sail in a book by Cornell and are going to look into this sail.

Its has to be used with a sock - pity it cannot be furled but it may be a sail we may get.

I am looking at what the sailers who have used this sail a great deal have to say and so with respect have to discount your observations.

[Talbot]

Latest blurb from the web site for the parasailor is 70 deg to 180. Possibly they have cut the sail rather flatter than in the past. If this is true, then it really is a usefull sail!

[Gludy]

In his book - A Passion for the Sea- Jimmy Cornell praises the Parasailor.

I have contacted the maker and I am currently researching the option.

I would certainly want to be able to hoist using one of your electric winches, and have it rigged with a sock.

I used to operate my own cruising chute single handed, but mine was a LOT smaller

Here is the Utube vieo of the Parasailor

And another video showing sailing at more like 90 degrees.

[Talbot]

Only thing I would have against it, is the apparent need for a spinnaker pole. That restricts the ability to operate short handed.

Is this video showing a parasailor being used on a St.Francis 50 or 44?
