Sage restoration advice wanted (osmosis)
I'm after some sage advice. Any and all advice, though, will be considered.
I've inherited a 26 foot GRP yacht currently moored in Canberra's biggest lake. The boat hasn't been sailed in over 5 years, but is largely complete. Apart from seagull poop, it needs new ropes, paint and most woodwork but the hull looks OK and she sits in the water fine, too. It has sails, most standing rigging, but the mast blew down and the step needs to be reinstated. The paint above the waterline is crazed, but the fibreglass down to the waterline looks fine all round (no bubbling.) Below the waterline is a lot of algae. The problems a a) I don't have a tender at the moment. The dinghy I was given was in worse (!!) condition and I'm currently repairing it. Currently accessing the boat by kayak. b) I'm going overseas for 12 months come January. c) Until 2005, I don't have much spare cash (I'll have a bit more when I get back.) So I've got 2 months to do what I can. At some point this boat needs to come out of the water for a full repaint, and to be checked for osmosis. My options are to either take it out now, clean it/paint it, then leave it on stands for a year before finishing the job. Or clean it where it floats, go away for a year, come back, take it out, and clean it up, fix it up and paint it. I'd rather do the second option, but I'm worried things might get worse if she's left in the lake. So, my questions a - Is it likely the hull has some osmosis? (AFAIK, it's mostly a salt water thing, right?) - If I just clean it up a bit (no more seagull poop or grass growing in the cockpit, clean bilge and working pump - preferably auto/solar) and leave it for a year, how likely am I to generate any new problems? I have friends/family who can check on her for me. - What haven't I thought of in restoring it? Any and all relevant advice would be nice. Cheers, Angus |

Haul the boat, clean up the bottom and check for osmotic blisters. If any are
present the hull will need to be completely dried. The year you are overseas would be an ideal period for the hull to dry, Upon your return you could make the blister repairs immediately thus saving a long wait after your return. Seek professional advice before attempting any blister repair. If there are no blisters you will not have wasted any time nor effort as you will have to haul the boat at some point in order to inspect it and to apply antifoulant. Good luck. Butch |

I'm afraid checking for blisters is not enough -- the hull can be wet
without any blisters showing. It is typical here (Boston, USA) to check boats with a moisture meter after they have been hauled and the surface dried. If there is any significant difference between the moisture reading above and below the waterline, the hull should be dried and barrier coated. With that said, Angus has left out some important information -- how old is the boat and who built her? The osmosis problem began to be recognized as serious in the eighties, so the later the boat and the better the manufacturer, the less likely you have a problem, as there was a gradual shift to the more resistant (and more expensive)vinylester resins. Swee****er, our Swan 57, built 1982 was wet (no blisters) when we bought her. While Nautor is a top quality manufacturer, 1982 was a little too early and, also, she had spent eight years in the Caribbean. We stripped the bottom paint, tented the bottom, and ran two dehumidifiers under her while we were doing the refit. When she was dry, we applied an epoxy barrier coat. This is a lot of work and your 26 footer may not be worth it. And, no, it's not just sal****er. Water's the problem, not salt. Questions to ask: You say "the paint above the waterline is crazed." Is it paint or gelcoat? Paint is unusual on a small glass boat and, unless she is very old, suggests that there was something to cover up. If the gelcoat is crazed, there are all sorts of potential problems. As a very general rule, wood boats are better off stored in the water; glass boats are better off stored on land. While you will probably have to pay for land storage, you should decide if the boat is worth it. Aside from that generality, as Butch suggests, a year out of the water is a good time to dry the hull. (It may not be enough unless Canberra is drier than my image of it -- you may have to go the route we went with Swee****er.) If a meter shows she's wet, you might put a dark colored tarp over her down to the ground on a good frame for the year and hope that the extra heat inside helps the drying. "It has sails, most standing rigging, but the mast blew down and the step needs to be reinstated." Sails in what condition? If they've been in the sun for five years, they're not sails any more. What standing rigging is missing? $$$ there. There's a recent thread mentioning US$2,500 to replace a mast step in a similar sized boat. Make a list of everything that needs doing. A conservative list, piece by piece, Can you do it yourself? As a very general rule (twice in one post -- remember that all generalizations are false) if you can do good work yourself, you'll increase the value of the boat more than you spend. If you do poor work yourself, you'll decrease the value of the boat. If you have a yard do it (in developed economies), you'll spend more than you increase the value of the boat. Bottom line -- get someone local who is expert to take a look and see if she's worth the trouble. Or try looking her sisters up using an advanced search on yachtworld.com to get an idea of values.

I would strongly suggest finding and marrying a very rich woman immediately.
This boat sounds like it's worthwhile to pursue. It would be best done with someone else's money. |

For gosh sakes, don't spend more than the boat is worth trying to repair
blisters. Have a qualified surveyor look at the hull once it is hauled out and the green stuff power washed away. If there is delamination, you will need to make repairs. If there is nothing more serious than garden variety gel coat blisters, yes, you technically have a "defect" but one that is never going to effect the structural integrity of the boat. A gel coat blister is like a mole on the butt of a beautiful woman- it "shouldn't" be there, but it does nothing to detract from the overall enjoyment or structural integrity . If you want to address the blister problem on a permanent basis, you will need to peel away all the existing gelcoat and the top layer or two of roving. Then get the hull as dry as possible. Finally, replace the removed layers with vinylester, rather than polyester. On an old boat, it ain't worth it. There is a huge failure rate when lesser methods are employed. Biggest effect that blisters have on a boat is their ability to depress the price when buying or selling. Funny how many guys who insist on a $10,000- $30,000 discount to accomodate "blister repair" put the exact same boat back on the market several years down the line with the exact same, untouched, blisters. :-) Typical conversation at resale time? Current buyer: Omigod! Blisters! What kind of crap are you tryng to pawn off on me? I need a huge discount! I won't even be able to use the boat for months, while it sits in a shed someplace, at $30 a layday, drying out! Current seller (who gave the exact speech outlined above when he bought the boat): Oh, fiddlesticks. Purely cosmetic. All those bllsters were there when I bought the boat. Never gave me a moment's problem. One of the portions of Dave Pascoe's site that makes good sense to me is his article about the considerations involved when acquiring a boat with blisters. Here's a link. http://www.yachtsurvey.com/BuyingBlisterBoat.htm |
