Did you ask the missing guide from North? They can probably also advice what is the correct tension in KN you need to apply.

I'd always use this as my go to source for rig info, rather than a sailmaker
Even though it's Selden specific, the wire tension suggestions are likely to be fairly generic and likely applicable to any mast brand |

Hi Matt,
I use the same Selden quide as well but thought Djgun needs absolute KN figures for standard wire which he can apply to dyform? shrouds. In fact the selden quide has KN figures on page 31 which together with recommended % tensin of breaking load may give the info that still needs to be applied for dyform shroud case and on this Selden quide may not give direct answer. No reason on my opinion to be shy asking advice and opinion from North or other applicable specialists.

Had my 370 rig on my 2007 model replaced this year. I took measurements in kilograms regard rig tension after the rigger set it up
Starboard cap 1150
Starboard intermediary 625 Starboard lower 625
Port cap 1200 8 mm Port intermediary 500 7mm Port lower 675 8 mm
Backstay on 400 Off 90 I have been really happy with how she has performed in winds up to force 7 and light winds too |

That seems odd to me. Apart from the difference between port & stbd one would surely expect a small even curve in the mast bend when set up without backstay tension. But if the lowers were higher tension that would make the lower section straighter- would it not? Or is that correct for a mast that rakes back ( Mine is a much smaller boat & the mast sits bolt upright) Then when one applies backstay tension the uneven tension on the 2 sides must put a side bend in the mast as one shroud has more tension already- Does that not stand to reason? Also when the mast bends the lowers having more tension than the mids will once again prevent an even bend in the mast. Is it too insignificant to make a difference? Of course , if the rigger sailed the boat with the mainsail up, then he would/should set the mast to suit the mainsail I know my Hanse is the smaller, but the lowers , when set with a loos gauge, are set at a lower number than the mids , because the wire is thicker & will give less. This allows the mast to curve more evenly. Perhaps I have this all wrong- especially as my mast is set so much differently to other hanse in the 311 size & it is nothing like the 40 ft boat the OP is asking about. I discussed mast shape with my sailmaker when he visited so my mast & sail match OK But some might want to comment as to why I am wrong

Thanks a lot Peter (Rock),
That is exactly what I was looking for. At last I can see a baseline. As has been noted by others, there seem to be some different J dimensions of Hanse 400. My 2007 build has J=435cm not 462cm as shown on this setup document. I seem to recall other owners have 435cm as well. Anyway, thanks again, I really appreciate it. Cheers DJ

Hi Silversailor,
The mast lower black band is always at the level of the top of the boom. I.e. top of black band =top face of horizontal boom. This applies to all yachts subject to official measurement for class rules and racing. So, you can run a straight edge along top of the boom, mark the mast with pencil then apply your own black band with 1 inch (25mm) tape below that mark. Cheers DJ .
