Dodgy through hull picture - should I panic?

You can go on and on and on in your usual way for as long as you like, I dont give a monkey's. You just become boring in the end

Some saw it as o possible problem som did not..


The best and correct advice was given in #2 and elsewhere, which was to look more closely or take a better photo. Advice which the Op sensibly followed

Yopu can stuff your new year resolutions ...... The forum is a far far better place with you on ignore. Although it would be even better without you.

I though you were in spain ...isn't there a Spanish boating forum yoiu could use?

Good grief guys; and take a chill Vic, you do know the rest of us can hear you - I mean you said all that out loud.

I can't agree. The whole assembly relies on the maintained strength of 3 bolts of unknown quality.

Nope - it also has the through-hull with outer flange screwed into it. From a structural point of view, the triangular plate with bolt holes takes the place of the small backnut we usually use on this side of the pond, and is obviously better. Trouble is, it's hard to obtain and quite expensive here, so not usually used.

Looking at something else, perhaps the Op can tell us the significance of the 2 white cable ties & what looks like a split in the hose

If he is in the habit of leaving the boat for a few hours with the seacock in the open position he might find there is greater danger from a source other than a dodgy skin fitting

I'd assumed that was a label of some sort.

I see, a nice piece of kit, although I not sure that it is a solution to a genuine problem. A well installed skin fitting and ball valve in bronze is perfectly good in my opinion.

What's wrong with leaving seacocks open for a few hours? Will something terrible happen?

An un-trimmed skin fitting with a valve on top and a hose tail on top of that always seems to me like quite a long lever with which to damage the fibreglass around the hole or even break the fitting above the nut, if something heavy were to crash into the upper end. But I must admit I've never heard of an actual failure happening this way, and it is the arrangement I've used on both our boats. I do always trim the skin fitting to the minimum necessary length (3 or 4mm between nut and valve) to reduce the leverage.

If you're the sort of numpty who repairs a major split in the hose with a couple of cable ties, then probably :). But I can't see any reason why the OP was accused of such numptyism. An optician could drum up some good custom from this thread, I think :D

I had a hose to the engine cooling water split & it did not drip whilst the engine was running, Presumably the negative suction stopped this.
However, having docked & spent several hours in the pub there was a lot of water in the boat when we returned

If you think about it, we all ( well some do!!) worry about integrity of the metal parts of the sea cock but the quality of the hose could be in question. particularly at the point where the jubille clip clams it & may actually cut the hoes- As happened in my case following- what i assume- was vibration

If you are referring to my comment re the hose, I feel that the comment that the OP was accused of numptyism was unjustified
I made a polite enquiry with no intention of suggesting insult

By coincidence there has been a report on the My Hanse forum in the last week of this happening to a boat involved in a bit of rock hopping. The grounding caused a sink unit to move ( no idea why but I think it was hull flex or something)& as it was cut tight around a pipe it sheared the fitting.

You chuck it around a lot DB, so don't be surprised if some of it bounces back at you.

Thanks, that's interesting. Must be a scary amount of flex in the hull to do that. Though I must admit I once hit a pontoon in a charter boat (morse lever came off in my hand!) hard enough to see the topside visibly bow inwards and pop back out again...

Not a problem I have with 40mm planks, but a fair point. On the previous boat with thinner planks, I would epoxy in a pad on the inside of the hull. This has two advantages, it beefs up the hull around the hole and gives a greater supporting length for the skin fitting itself. I prefer that to trimming down the fitting.
 
Fitting looks fine in second piccie. Can't believe I read nine pages just to see if someone was gonna comment on what looks to a be a way bodgy job clamping a split pipe with cable ties. I would seriously consider checking the pipe rather than worry about the fitting.:confused:

Obviously you didn't read "9 pages " properly. See post 87.
