Hello to all Captains,
I am the owner of 39 DS year 2008. I bought this boat for cruising purpose. I am living in Turkey Bodrum.. Time to time we are using my boat for racing and we are attending winter Bodrum regetta... I need your thoughts and experiences how do I improve my boat performance. I know I am stuck with the size of the jib and main sail. My questions are:
1- What is most suitable fabric for sails ? (my mainsail is furling type)
2- Is there any way to put bigger jib?
3- To put a folding propeller is a solution? If yes which type and which brand?
Many thanks for your help, understanding and cooperation..
TELLI

Dear Kaptantelli, I have the bigger 42 DS and .. Same problems…
For the main sail is a very big problem since no sail maker will guarantee you a better speed with that type of sail, moreover the real sail “engine” of our boat are the front sails, I mean that you should ask for a bigger furling genoa perhaps in membrane (I gained more or less 1 knot) . For the fabric I can suggest you Elvstrom or North Sail, but as usual the price drives since almost all of them use the same materials.
For the propeller I guess that every folding propeller is good for sailing but some of them are really bad in reverse mode, someone told me that kiwi propellers are very good, but autoprop, eowel, maxprop, flexofold, Gori are used a lot and so the best advice is to search on the net there is a paper in an old Yachting Monthly issue with a large comparison of propellers and with the description of advantages and disadvantages.
I hope this replay is useful…
Good luck and ejoy the wonderful Bodrum

I have he same boat 2007 model
Sailing performance wasretty good when the sails were new bit after about 5 seasons of use performance dropped noticeably. Year 6 due to an injury (not sailing related) I did not sail much so did not change them. Season 7 the drop in performance was totally unacceptable.
After a lot of reseach I ordered radial hydrant from Jeckells. They offer better performance at essentially no price premium over Dacron. Will fit them over Easter and do some tests with fingers crossed.
I was told by all sailmakers I talked to that they would no recommend vertical batters. Tose who were willing to make vertical battens sails for me did ot recommend them. Des McWilliams said that they have taken them out of most sails they originally pt them in. I am hoping that the better shape retention of he hydrant will make up for the less powerful shapedue to having no roach.
On the prop side I would suggest you stay away form the kiwi. The increase in sailing speed was circa .75kt with a loss in speed under motor of circa 1kt. However over a period of three years the performance under engine started to decrease. By the end of last season I found it impossible to get up to 6kt in flat water and no wind.
Local jeanneau agent said he had found problems with th kiwi on boats of this size. He believes the kiwi is not suitable for boats of the awaterlength and weights of the 39ds. He has also found problems being caused with the gearbox on boats with kiwi. My boat is now out of the water and I have refitted the original thre blade fixed to make sure I can still get the original performance. When I am happy there has been no mechanical damage to the gearbox I will start to look at other options folding and feathering.

Hi kaptantelli,
I have sailed at Bitez and when we were there it was really windy every day except one so perhaps sail shape is more important than getting more area.
I think your genoa area is limited by the gunwhale mounted stays so you can only go as far back as the lower spreaders but if you are serious about racing I would get a full hoist genoa that goes from the deck to the mast halyard. By bypassing the top and bottom furler part you could gain 300 mm of luff length which is very useful. It helps with the end plate effect on the bottom of the genoa too. For the non furling genoa I would go for a laminate with lots of carbon. We are very pleased with our Dimension Polyant GPL in our radial cut genoa. It holds its shape well and is light enough for light conditions and strong enough for up to 20 knots of wind. It is also quite easy to fold up after sailing, has no taffeta on it to hold moisture and is light to handle. What more could you ask?
For the furling main I would go with a radial cut hydranet sail as this will do for both racing and cruising and you don't want to be changing the main over.
Most important is to have a really clean hull and scrub the bottom just before the series. In my case I have also removed all the mushroom head skin fittings and replaced them with flush skin fittings. This works really well in the lighter conditions.
Regards
David
