I finally got my new North Sails 140% (27.2 sq.m) Genoa for my Hanse 315 yesterday. It's "D-cut" and "Norlam 5,4XP". My first impressions is that it is a beautiful sail, perfect quality. From North Sails in Turkey.
I sailed it yesterday for 7 hours in 7-9m/s wind, here are my feelings:
- The work-load more than doubled when tacking - this now became a pretty complex operation (sailing solo). There are a lot more things to go wrong, and the cockpit has a lot more ropes in it.
- The self-tacking (85%) jib is very good sailing close to the wind. Possibly better than the 140% Genoa.
- You are over-powered a lot, and need to reef more often. Increases workload.
- The 140% easily "back-powers" if you go to high, and you must do a full tack to solve this. The 85% is extremely forgiving - it just flutters a little.
- Downwind sailing with a spreader boom with the 140% is perfect - a lot more sail area, higher speed, and the boat is much better balanced and feels safer.
- Higher speed when not sailing very close to the wind.
All in all - If the sailing involves a lot of tacking, stronger winds and sailing close to the wind, I'll prefer the 85% anytime. And the Hanse 315 with the self-tacking 85% jib is a very good and user friendly sailboat!!!

Thanck you Frode, you've been so clear! I've got some doubt about getting a new genoa and your post has been usefull because you haven't spoken only about speed! Ciao

Frode,
how does this sail look like if you furl it in a bit?
I.e to 110%
Can it still be used, or do you need to change to the JIB?

Rune, I will try to test that over the next weeks. I'll let you all know! ------------- Frode, Stavanger/Norway Hanse 315 # 390 |

Frode,
Interesting observations that make a lot sense given some of the things I've heard. I have a 400 and was considering an overlapping genoa for racing in low winds.
You mention you likely don't point as high with the 140. I was warned that likely that would be the case, wide cabin tops (meaning genoa tracks more outboard) and shrouds that were more outboard would cause this - just can't sheet it in to a tight enough angle.
Also, it was suggested that an overlapping genoa would likely be too much power for anything over 10knots (5-6 m/s) because of our big mains. So it's not at all surprising that you felt overpower in almost twice that wind strength.
I've been using a maxi jib for racing, about 108% and definitely am at a disadvantage with light winds (6 knots) but when the breeze is 10 or above we're very competitive.
As for a couple of added lines in the cockpit - you need to add some more cupholders so the G&T doesn't spill when you put it down to do the tack
 Cheers
Steve

Hi there, i got my 140% genoa last thursday, just before a trip from the Netherlands to Ramsgate (UK). Some pictures: http://www.uisge-beatha.eu/index.php?mact=Album,cntnt01,default,0&cntnt01albumid=13&cntnt01returnid=45 - http://www.uisge-beatha.eu/index.php?mact=Album,cntnt01,default,0&cntnt01albumid=13&cntnt01returnid=45 One of the photo's show the instruments :) The speed sure was higher with this new sail, only it is not build for close wind sailing. I used it up to 18knts true wind, than I rolled it in. I'm satisfied with it's performance Cheers, Gregor |

hi frode,
i too plan to get a 140% genoa for the 315.
i got the brochure that says the sail area for the 140% genoa is 33.4sqm, 360sqft. and this is from north sails.
seems like your sail is a bit smaller? is it high cut so there is less sail aea?
also, when you furl in the sail, will it furl in completely or do you take the sail down. i am currently using a harken furler, and there is a maximum amount of rope that can be wound onto the drum before it becomes full and will jam with some of the sail still not furled in. same thing for the furlex furler(hunter326). just wanted to know if the facnor drum can take all the rope.
frode, your genoa looks great! i am unable to tell from the photos, but do you have uv protection on the genoa?
cheers

Today there was ideal conditions in the Gandsfjorden, so I did a test tacking against the wind to see what was the best performance I (with less than 2 years sailing experience) could get from my Hanse 315, sailing single-handed, with the 140% Genoa, and the Mainsail with either full or none reefing.
Here is a GPS print with tack angles and GPS speed added:
 Comparing this with the Hanse 311 polare for 140% Genoa, I have marked the speeds and wind angles with "X" on the polare:
 Please note that I used the autopilot on most of these legs. When controlling the tiller manually, the performance is the best.
My conclusion:
I can now manage to sail close to 40 degrees to the wind with full sail area, and perhaps 44 degrees to the wind with the fully reefed mainsail in similar conditions.
It was possible to achieve 6.0 knots at 45 degrees or better to the wind
 , which will now be my VMG (Velocity Made Good) target when tacking.The reefing of the mainsail reduced the boat speed and wind angle a bit.
The sails may look ugly when going high into the wind, yet still give good performance.
PS! Reefing the Genoa did not work well for performance when aiming high into the wind. but is fine when the wind comes directly from the side. Then it helps a lot to reduce over-power. ------------- Frode, Stavanger/Norway Hanse 315 # 390 |

Thanks again for sharing this interesting information, Frode! I wouldn't like to race against you with those angles and speed...

Hi Leslie,
I'm sorry I didn't see your post earlier.
With the listed rigging dimensions of I=12.20 and J=3.65 for the Hanse 315, the 85% Jib should in a simplified calculation (guessing that the foot is cut 20cm above the deck) be 18,3m2 (is 16,0m2) in area and the 140% should be 30,2m2 (mine is 27,2m2). The curvature of the sail may add slightly to the sail area. So both my jibs are probably "high cut".
My sail is the North Sails "Furling Genoa 140% D-cut 27,2m2", which is in their brochure for Hanse 315 sails. The sail overlaps the shrouds only in the lower part, so I'd guess the sail is 140% in the lower third, and more like 120% in the upper two-thirds. Which is fine with me. When sheeting in, if the foot slightly touches the shrouds, the upper parts of the leach come within and just in front of the shrouds, so it is probably possible to sail slightly higher to the wind than an "un-cut 140%" would have allowed.
Leslie, the furling line is fine on the drum. You only need 2-3m more line. Do you have a too thick furling line. Only 6mm in diameter should do fine. The 140% furls all the way in, easy.
I've noticed that the wind over the main-sail appears better with the 140% than with the 85%. The tell-tales are flying much easier now.
Cheers,

thanks for the reply frode,
no apologies needed.
i have ordered a 315 #705 and due to arrive in sep/oct, so i am researching for information in this forum..... and this is a great forum.
i sail by myself or with my wife who is a non-sailor and my son so i had inquired to upgrade the winches for the genoa, they now come as lewmar 30self tailing. i find this would be too difficult to winch (33sqm) from the point of view of my wife and my 11 year old( i assume my wife and son will single hand this boat as well). but hanse cannot/will not let me upgrade this winches, which is why i asked you the question on the genoa size. at 27m2, lewmar 30 is good enough. so i can now decide maybe to get the genoa...or
my first thought is to get a code zero with a furler, or an asym with a snuffer or cdi/rollgen furler , but perhaps a genoa(not so big) would be better choice.
i suppose you are happy where the traveller location for the genoa blocks are located for your new sail?
yes i use 8mm furling line , perhaps this is the reason why the genoa does not furl completely. (the 8mm rope was part of the harken package).
i agree, air flow on the main would be better because of the genoa, wind will stay attached longer than the 85%.
less damage on the sails if the sails do not touch the spreaders/shrouds ....maybe your sailmaker has got it right!!
i test sailed the 315 and loved it, wife did too!! so now i'm just waiting.
cheers

I did some measurements last Saturday (150% genoa): SOG True wind True wind angle 5,8knt 12,9 30 5,2 10,4 40 5,5 8,9 45 5,5 8,2 50 6,0 9,9 50 6,3 10,8 55 6,0 11 45 5,5 11 45 5,9 11,3 50 6,0 9,3 60 5,8 9,3 50 The next two are with are reef in the genoa (rolled in). No reef in the main sail 5,1 10,3 45 5,8 9,7 50 I noticed that the rails on both sides are 30cm short. How to make them longer??? Greetz, Gregor |

very interesting gregor, when you reefed the genoa is it about 130or120or110%? seems very decent speeds for a reefed genoa. would have loved to see your results for true wind at 30-35degree with a reefed genoa!! when i sailed the test boat, in about 10kts, i was sailing apparent wind 22-28degree, this when feathering the self tacking jib, so no suprise your boat goes to windward well. sorry can't help you on the rails.
thanks for putting up your findings
