Swan 40 - Deck elevation near chainplates I am looking at a Swan 40 that is in good conditions (sail only in fresh water)except for a small elevation in deck level near the chainplates ( both sides of the boat). Looking below deck after remove the roof finishing all seems OK.Should be water infiltration in the balsa core of the deck or a structural problem? Many thanks Marco |

Like Mike I've done this repair on my 40, not complicated, the main thing is to come straight down from the chainplate to the hull. I have been living aboard for seven years, and know of another 40 owner that has done for more than that. |

Hi Marco, This is a rather common problem. I have repaired this on mine and know of a couple of other 40s who have repaired the problem using a similar approach. This is a result of over tensioning the rig. As far as water ingress, I have not heard of anyone with a problem due to this. Do not view this as a large problem. As for the deck,I think it is marine plywood glassed on both sides not balsa core. Maybe others can verify this. The 40s are a great boat. We are very pleased with ours. All the best Mike Hi Mike. Thank you for replay my notes, your comments was very herlpfull and I am going to buy the 40. I hope see you soon in the site or in the next S&S Swan meeting. Good winds, Marco |

The boat is going to be located at "Angra dos Reis", Rio de Janeiro state, at 70 miles from Rio de Janeiro City. Althou Angra be a nice place to sailing (we have a bay with 365 islands) I intend to cruise in Caribean sea and Mediterraneum, as soon as the boat is prepared. Marco |

Hi Rod, I didn't get it. I will be happy to help if I can! Cheers MIke Hi Mike, I finally put a new prop on Fandango, this is after The prop aperture was opened, and a new engine went in the boat. So I now have a 37HP Kubota (Phasor) with a 16X10 prop. When I acelerate above 2100 rpms I start geting water into the cockpit through the drains. If I push it more, the transom sucks in and I get 2cms on water in the aft cockpit. I don't know what engine you have on your boat, or if you have experienced something similar and if you have, what have you done. |

Hi Mike and Ron, I just wanted to inform you that I last year installed a new Vetus 44 hp engine in my S&S 40 and have had no problems like the one you described with water coming in via the cockpit drain. The motor was relatively easy to fit under the original hood and I am very happy that I decided to take one step further up from the earlier Yanmar 27 hp which was too weak for the boat especially in high sea with high short waves. In addition to the new stronger engine I also installed a Kiwi feather three blade prop which turned out very well. Not only is it now possible to go backwards which was earlier a great problem it also has a very good ?drive? even at low rpm, and got new life to the boat and finally it seems to give much less resistance when sailing. I was recommended this prop by our S6S 40 collegue in Cheers Leif Sunniva V (S&S 40 #36) |

Hi Mike, sorry for the delay, and thank you for your ideas. I just finish cleaning the fuel tank so that I can do a good seatrial and find out how many RPMs am I missing. I had about a 1/4" of slime around most surfaces of the tank. For the seatrial I'll probably use ceder plugs on the cockpit drains. I could not find a drain with a check valve that can work in there, plus if I take a wave inside I would like for the water bail out fast. I think my problem could be the larger prop (from 13" to 16") which gives a lot more thrust. Mike I know you told me before, but I forgot what size are you new winches. Cheers, Rod |

Hi Leif, I am glad you are not having my issues on your boat, I am curious to know what size prop you have. In my case puting a 13" prop back into the boat will be like wasting engine, that's why I went with the larger prop. Cheers, Rod |

Hi Rod, Sorry to be late in answering your question, but I just recently observed your questions. My Kiwi prop is 17", pitch degrees 21, shaft size 30 mm It has been working nicely this summer Fair winds, Leif S&S 40 #36 |

Good choice, you will enjoy her I am sure! Anyway, somewhere I have a powerpoint figure of what I did to fix the problem. If you need it just mail me. Fair Winds Mike Hi Mike and every other swan 40 owner
I am continuing restoration of Teragram. I also have lifting decks been on list for several years now and re rigging so looking to deal with. be great to see pics or plans of how you guys dealt with the issue. I dont see it as structual it is asthetics that i want to solve. Cliff Teragram |

Dear Cliff Deck lifting locally is a structural problem, and a common reason is that the chainplate knee inner ends are not properly supported against the coachroof coaming.
Suggest you send photos of the knees for evaluation.
Kind regards

Hi Cliff,
I got your message, and will try to dig out some drawings I made. It is a relatively easy fix. Requires glassing a SS plate with an eye into the hull below the inside end of the elbow and then adding a turnbuckle and either an SS rod or some SS wire to attach to the eye. Easy... just messy as you have to grind along the hull to get to the glass ensuring a proper bond with the hull. This is critical as there is a lot of load on this attachment. I discussed this fix with Lars many years ago and I have lost track of how many 40s have done this modification..
i have the pictures on an old computer... I should probably send them to Matteo to upload on the site... mental note to me... Great boats!!!!! We love ours...she has taken us to many adventures!! We, a family of 4 lived on her for a year while doing an Atlantic Tour... Fun!!!!! Fair Winds
