There's a hole in my bucket

You mean this part is actually broken, not the transducer itself?

Best bet is as others have said, glass it over. But, if you measure the diameter, maybe you can buy another + a blanking plug.

Yep, just the plastic housing is broken ... but point being is that it dosent need to be there and I don't want it there.

Anything in a boat that I take lives out in I will know everything about, that's berths, engine etc - and I'll be the one who has antifouled it on dry standing just so I can get a look at the hull below the waterline to know every inch of it.

So yes, this thing isn't getting put back in... There's a hole.

Thanks for the "fibreglass it" but that is not what I want to do, if I wanted to glass it I'd epoxy it and feather it in... My question again again is about a skin fitting with no hole...

I know nothing about this log doofer, nor do I want to - there is no head for it, - it just needs to be gone.. there is no need for it to be here... I just want to block the hole.....


Kind regards

1) You could pay a machinist to make what you want. Couple of hundred quid?
2) You could pay a parts engineer to search out something that would do the job. I've been in industry and seen people spend a few man-days at £300 a go search for parts and then revert to option 1.
3) you could do the job with readily available parts, vis a BSP skin fitting, a bsp blanking cap and a couple of back nuts.
Or spares from an instrument supplier.
4) you might chance on some random thing that looks suitable and not know if it's good for underwater service or not
5) you could get something modified. e.g. find a stainless fitting and get the hole welded up.
6) you could replace what was there originally.

3 and 6 seem to me the sensible options.
3 gets the job done with parts fit for underwater service, probably lowest cost, risk and least hassle.
6 could be seen as adding value to your boat. You may not appreciate the benefits of a speed log right now, but you might come to do so later. You might want to sell the boat at some point, the absense of a speed log might not help.
 
As others have said, most of these log gizmos come with a blanking plug so that the log can be withdrawn and cleaned while afloat without sinking the boat. The manufacturer may well be able to supply a spare replacement skin fitting and blanking plug. Alternatively, another manufacturer's skin fitting and blanking plug would do if they are meant for the same hole diameter and you are sure you are never going to refit the instrument.

AFAIK no-one makes a blanked off skin fitting because there is no demand. If there's a hole in the hull folk will either use it for it's intended purpose or do a permanent job of closing it.
 
Why hasn't a skin fitting blanking plate been invented yet?

Same reason a skin fitting suitable for a 12mm thick hull, with 1-3/4" ball valve with the handle facing inboard, with a 19mm hose barb angled forward at 45 degrees, hasn't been invented yet.

Because they can't cast and then stock every single combination anyone would ever need in a single piece of bronze. Instead you go to the ASAP catalogue to buy all the pieces you need and then screw them together.

In the case of a "skin fitting without a hole in it", that's a skin fitting, back-nut, and female blanking cap. Cut down the stem of the skin fitting (they're made over-long to go through thick wooden hulls) so that there's just a couple of millimetres of spare thread between the back-nut and the cap when fully screwed down. That'll make a fairly low-profile fitting in your bilge that's not going to go anywhere.

I have a couple of fittings blanked off like this from old plumbing.

This is the wisest reply so far..

Why hasn't a skin fitting blanking plate been invented yet? It would be so easy to do and obviously just as strong as other skin fittings..

Confused wooden trawlerman..

I sealed 2 unneeded skin fitting in the transum that way.

You really aren't the slightest bit resourceful are you? Shame on you! Why don't you do what this guy did?

That is exactly what the previous owner seems to have done on a different skin fitting, it's plugged up and jubilee clipped but as a Wooden boat man I don't compute to that... I'll have to get 2 great big washers, a stainless steel bolt and nut and Sikaflex...

Someone should Dragons den this

Don’t forget you also want to try and keep the plug fairly flat on the hull to keep it smooth as possible through the water
 
Thanks all and as usual some of the usual suspects put the thread on a tangent.. I'm not over complicating it, im simplifying it.

I want a skin fitting without a hole...

They are readily available. They are called machine screws, but more commonly known as bolts ;0) However, googling tank blanking plugs reveals a wealth of stuff.


See here for a few ideas:

Is there any thread left on the original skin fitting? Can you source a blanking cap to fit?

Last resort, get a mate to turn a few up and put them on eBay. You may corner the market.

You are my new best friend for this week....

That is exactly what I'm looking for.

Thank you, there's a beer in the barrel for you if you ever get across the water to here.
