380 Standing rigging

[Toolittletime]

I recently had my standing rigging inspected by a local shop here. There conclusion was that it is in "serviceable" condition...privately the rigger estimated the age as 10 yrs or so.....in good condition.
When asking him if there was too much bend in my furling selden mast....he replied......don't know.....??
Also said he was not a fan of the BR rig...

My question to you all is this.........from my reading of the specs....selden calls for NO bend in a furling mast.......I have about 4" or so.

Can the rigging be adjusted in place without dropping the mast?

I think this is the biggest contributor to making the mainsail hard to furl in and out.......original sail probably doesn't help either.

I plan on taking the main off this winter and servicing the furler mechanism. I really hate to take it to the yard and having someone not familiar with this rigging to charge me 250.00 for an inspection and do nothing to resolve the problem or offer suggestions.

Anything else come to mind............Thanks

I think it’s a settled matter that there should be minimal bend in a mast with a furling main. You should have just enough so that the mast is clearly not inverted.
It is intuitive that something that turns will be more difficult to turn if it isn’t straight.
The rigging can be adjusted on the boat but as far asI know most riggers tune B&R rigs on the ground. If it’s on the ground and you find a problem with a shroud or stay it is an easy thing to remove and replace.

I talked with a rigger yesterday and he says that he can adjust the rigging, using their cherry picker, and can get the mast straight if there is enough adjustment room in the turnbuckle system. Estimated 1 hour or so of labor.
I will report back here in a couple of weeks after this is done.
I personally think the rigging was replaced a few years back, and was adjusted with a curve by a rigger not familiar with the b&r in mast furling.

I also looked at 2 similar boats in my marina. No bend in mast on either one.

"The bend in the
standard mast should be about 4”
[100mm] and 1” [25mm] in the furling
mast"

from the 2005 hunter 41 manual. I have bend in mine and it has caused no furling issues. I have had issues when I tightened the inner furling foil too tight. All on me.

 

[Toolittletime]

Yes, I plan to check the tension on the foil, and lubricate the moving parts as soon as I have some help with the sail.
Thanks

Where did you get the no bend in the mast from? When the rigging is built, the mast is tensionned on the ground which imparts a little bend.

See page 52, 53 of the hunter factory manual. It's measured on the ground before hoisting the mast.

You can adjust for lateral bend and downwind shroud loosening under sailing load but the rest needs to be tuned with the mast unstepped.

Get a different rigger. If they don't like a b and r rig they don't understand it. Each rigging type has pros and cons. The b and r makes for a balanced and incredibly easy boat to sail, except no sailing with main up below 150 degrees. It was designed for racing ....

Doesn't mean their boats are right or that that they have the same rig? Use the owner's manual for your boat. Lateral or fore-aft bend? Fore aft bend should be there (4 inches) for the furling mast.

 

[Toolittletime]

Per the selden manual that applies to my particular mast on my Hunter 380....
Calls for bend to be from 0" .....to 2" maximum.

 

[Toolittletime]

Interesting enough the 2 other boats in my marina are Hunter 380 with furling mast and have no bend.
No trouble furling either.

Use the hunter manual, not the Selden manual. The Selden mast can be used on different rig types and it's generic. Hunter manual has all the specs for your boat .

 

[Toolittletime]

Per my Hunter 380 manual......................which I think is exactly what I have been saying!

 

[marcham]

From the Hunter 380 owner manual? Strange.... I have 2 different copies from different years (digital obtained from Hunter, printed came wtih the boat), both specify 4"..... What year is your boat? Can you post a copy of the manual in the H380 files section?

My rigger works a lot on B&R Rigs (Hunter, Beneteau, etc...) new and old, he was perfectly happy with my setup at around 4" of bend. Mainsail goes in and out by hand, no winches needed. Mine is a 2001.

My Beneteau Oceanis 31, also B&R rig had a shit ton of bend in it, as per the factory setup guide, but that was a traditional mainsail. (not in mast furling).

Do you have any furling issues? What is more critical than the bend in the mast, is the tension set on the mast furling system.... mine came too tight from the previous owners, slacking just 2-3 turns made a night and day difference in furling/unfurling.

Given the significant back sweep of the spreaders, I don't see how the mast can be tensioned on land without imparting some mast bend. To not have mast bend would mean the D1, D2, D3 would be undertensionned. They are what provides structure to the mast. So no tension = weak mast =no bend.

It's not a H376 or H38 manual is it? I believe they had different mast lengths which would change the amount of pre-bend.

 

[Toolittletime]

I will post the manual. It's a 2002 380. Yes, have to winch and feed the first 5 ft or so of the main.
Have not checked the tension yet.

 

[Toolittletime]

Check the 380 manual already posted by Viper....its the same as my printed one.
Page 52...section 1...Tuning the 380 B&R rig....that where I got the quote.

 

[marcham]

We're looking at the same book. 2 in is what is set on the ground before hoisting the mast, 4 in is roughly what you see when installed and tuned on the boat.... i assumed your mast is standing?

If you're using the winch to pull it out, the sail is loose when being furled or it's blown out. Having the rod kicker at the right support angle is also important.

Is it original ? In mast furling systems do not like old blown out sails.
