David Florence Posted August 31, 2020 Report Share Posted August 31, 2020 Last night there was a big mettalic "ping" and it seems the weld cover at front of boat near waterline has come away due to rust. Temp repair made with Sikaflex, and obviously I need to get it out of water and repaired. My question is, (and I know its a how long is a ball of string question) but from the picture below, what ball park costings might I be looking at for a repair? (based in leeds) TIA Link to comment Share on other sites More sharing options...
Machpoint005 Posted August 31, 2020 Report Share Posted August 31, 2020 That's only the rubbing strake - no need to panic. My impression is that it's only the weld on the edges of the strake that has failed, so it shouldn't affect hull integrity. The welding will cost a lot less than the haul-out. Take the opportunity to black the hull at the same time. 1 Link to comment Share on other sites More sharing options...
Bee Posted August 31, 2020 Report Share Posted August 31, 2020 Can you drill through that half round bit that is flapping about and then through the hull? if you can get to the other side you can put a nut and bolt through it, if you can't get to it then drill and tap it then bolt it.

Great idea until the next owner in years to come takes the boat out onto the wash only to find water ingress due to a rusty bolt where you'd hope not to find one!

BWM Posted August 31, 2020 Report Share Posted August 31, 2020 It looks like someone has hacked a small section out to install an outlet and not taken the trouble to weld the ends, if you can find a mobile, canal based welder and a place to moor with a low towpath it should be possible to get it tacked back on without a docking. 2 Link to comment Share on other sites More sharing options...

David Mack Posted August 31, 2020 Report Share Posted August 31, 2020 It doesn't say much for the quality of the original welding that the rubbing strake has unzipped so far back from the point where it has been cut. My guess is there was a token continuous weld along the top edge and just tack welding (or virtually no welding) along the bottom edge. I would be minded to get it welded or bolted back in place for now with the boat in the water, and then when the boat is next out for blacking, take a good look at the welding along all of the rubbing strakes, and get any defective bits repaired before reblacking. Make sure too that the cut end forward of the water outlet is properly secured as well. 1 Link to comment Share on other sites More sharing options...

There appears to be a skin fitting in the gap, my guess is a deck drain or more likely a gas locker vent. With that being the case i would just chamfer the two ends. 11 minutes ago, David Mack said: It doesn't say much for the quality of the original welding that the rubbing strake has unzipped so far back from the point where it has been cut.

I think a number of modern boats have stitch welded strakes bedded on sealant, i think the sealant is the visible line that remains at the top.

dave moore Posted August 31, 2020 Report Share Posted August 31, 2020 Piss poor practice if that is the case, decent yards weld top and bottom continuously. 3 Link to comment Share on other sites More sharing options...
Tracy D'arth Posted August 31, 2020 Report Share Posted August 31, 2020 Don't drill holes in a sound hull unless you are going to rivet. Bolts and nuts or tapped holes in 6mm plate are potential failure points. It ain't Meccano. Simple job for a mobile welder, heel the boat over as far as possible.

If it was my boat would have a prod about on the strakes/hull joins looking for proper weld metal. This will quantify how much may need welding up.

I'm all for lateral thinking but that seems like a particularly bad idea. The last thing you want on a rubbing strake is a protruding bolt head just waiting to get knocked off. As others have said you don't want to drill through the hull unless you have to. I'm not sure if that skin fitting is a gas locker vent or something else but you might end up drilling into the water tank for example. 52 minutes ago, Tracy D'arth said: Don't drill holes in a sound hull unless you are going to rivet.

Yes, it doesn't really need to come out of the water to repair it. Link to comment Share on other sites More sharing options...

I don't recognise the longitudinal weld below the rubbing strake as being scouse in origin. 1 Link to comment Share on other sites More sharing options...
