Boat weight and replacement lines
bobmichigan2004
My Dad recently gave me his '73 AMF Sunfish. I knew nothing of the
proper way to store it so it sat upright on its trailer wrapped in a blue tarp for about a year (he had it stored in his garage for years). Well, surprise, surprise, when I went to get it ready to sail last weekend the cockpit and hull were full of water. Nit-wit that I am, I did not leave the drain plug open so rain water filled the cockpit and leaked into the hull through the air vent (at least that is how I think it got in the hull). Pretty stupid on my part. Well, as I drained the water out through the drain plug (it probably took 25 minutes, eek!) I could hear air being sucked into the hull in two places: a small hissing at the mast hole/step and another at one corner of the stern. I could not tell where in the mast step the hole was, but it was a very, very little hiss. The hole in the stern is more obvious, as it looks like the boat was dropped on that corner at some point and cracked. The hissing was easily heard while standing a few feet from the boat as it drained. This morning, I read through the posts on this forum about drying out the hull. I will try to weigh the boat tonight or tomorrow after work. I suspect it weighs less than 200 lbs because I could easily lift and slide it back on to the trailer myself. It may weigh quite a bit less than that. From what I read here, I assume that if I repair the small crack in the stern that it would cause the boat no real damage to sail it weighing in the 150 to 200 lb range? If it is that heavy, I will install an inspection port and begin the suggested drying methods, but I would like to sail it this summer, and it soulds like the drying times are measured in months. Another question I have concerns the centerboard/daggerboard (not sure which term is correct). The bottom-leading edge has been damaged over the years by running it aground. The wood is quite smashed/frayed for maybe a length of an inch or two, to a depth of maybe a half an inch, maybe a bit less. I'm not sure what the right words are to describe its condition, but you can see the individual wood fibers all seperated where it is damaged. Any sugestions on how to repair this? Last questions. The halyard shows a lot of wear, suggestions on what type of line and where to buy it? Also the outhaul lines were both broken. What is the correct type of line to replace them? Thanks for the help/advice. Bob |

Hi Bob,
Well, as I drained the water out through the drain plug (it probablyEek! is right.... OK, now let's reverse that process and blow a little air into the hull. While doing this go around the boat with a spray bottle filled with soapy water and spray all the edges, nooks, and crannies. Now instead of a hiss you will be looking for bubbles that indicate all the leaks. See: for a good technique that won't blow the seams apart. I assume that if I repairJudging by your description you may have lucked out and the foam floatation hasn't taken up much water at all. It is my theory that floatation blocks immersed in water take up little or no water while blocks constantly exposed to warm humid air take up a lot. This is based on the idea that closed cell foam is designed to be impervious to water in it's liquid state, however, we have observed over and over the cell wall material succumbs to osmosis when presented with water in it's vapor state. Therefore, I believe a boat with a little leak that never gets dried out is at higher risk than a boat with a noticeable hole that takes on gallons, but gets emptied and well dried between uses. So, this is why installing an inspection port is crucial even on boats that don't appear to have any leaks what so ever. Really, the factory should have been installing inspection ports as part of the design long ago. [stepping down off of my soap box] ... Sure thing, fix the leaks and go sailing. Another question I have concerns the centerboard/daggerboard (not"Daggerboard", typically "centerboard" is the term used to describe one that is attached to the boat and swings into position as opposed to a, Dagger-board which is "stabbed" through a slot or "trunk". The bottom-leading edge has been damaged Sure, use a hand-held wire brush to clean the exposed wood grain. Fill the dings and chips with a plastic wood filler -or- better yet (assuming you have some knowledge of fiberglass repair) make your own filler using polyester resin and milled glass fibers. Sand and shape the repair then varnish or polyurethane as desired. Personally, I'd refinish the entire board. If the splitting wood runs up the board and appears to threaten the integrity of the whole board, you can wrap it or lay on several layers of fiberglass cloth in the usual fiberglass repair manner. Last questions. The halyard shows a lot of wear, suggestions on whatI don't know the line lengths off the top of my head.... probably something we should post in our library of information, eh? I'll work on that one..... You probably have several bona-fied Sunfish dealers within a reasonable driving distance (unless you are in the UP) 8^) They can fit you with the right stuff. If there isn't a dealer, or any sailboat shop for that matter, in your vicinity contact Dan at Wind Line Sails There are many Sunfish dealers, Dan is just a personal favorite because of all the help he's given me and his devotion to promoting the sailing sport at every level. Hail the group again if this doesn't help or you have more questions. Wayne |

Thank you for the response, Wayne.
I did weigh the boat last night. It weighs 149 lbs, so not too bad I think. Did I read somewhere that 138 lbs was the "factory" weight? In looking more closely at the damage to the hull, it is right on the starboard corner if the stern. I'm not sure that I want to try to repair it myself because it is not a flat surface. Any guess as to how much something like this would be to repair? The crack/hole is about an inch and a half long, maybe one-eighth of an inch wide. Thanks for the help and advice. Bob |

I will venture a guess-timate of $100 to $200 to have a boat shop fix your hull. Boat repairs tend to be a bit labor intensive so the price gets up there quickly. If you are game to learn a little fiberglass repair, fixing a crack or hole at a curve is no more difficult than one on a flat surface. If the crack goes through to the inside it will be best to install an inspection port for access. You will want to lay in a strip or two of fiberglass cloth on the inside to back up the repair spot. Beyond that it's a matter of scraping and opening the crack to clean away any loose material back to undamaged glass. Then filling the area with fiberglass materials or epoxy filler. The last step is to sand the repair smooth to match the surrounding hull. Check out, "The Fiberglass Repair and Construction Handbook" by Jack Wiley Good Luck, Wayne -----Original Message----- |

That's a nice chart of lines APS has there. The same information is in the tuning guide, but it's in the text for each corresponding section of rigging so it's not as easily found. Last time I replaced my mainsheet and halyard I bought about 4' extra line for each. The halyard I trimmed back to about the stock length, but the main I left long. I appreciate not having to hang on to just the stopper knot when on a run. Have you seen this Vanguard article by Dave Kirkpatrick on rope characteristics? It helps to sort out the different styles of line available. Thanks for sharing that APS find. Wayne -----Original Message----- |
