Gribble

[eyupdougdown]

Hello, I am newish to the sailing game and am part way through the second stage of restoration of my 1953 Maurice Yacht in Millbrook, Cornwall.

Amongst other things, I have been advised by the Yard Gods that the new planks on the hull are too hard below the waterline - and need special organic treatment to give them an authentic classic internal texture.

They have recommended that I get some gribble eggs and put them into the boat somehow when she is back in the water.

Does anyone know where I can get some and what is the best way of getting them to flourish? I have also been recommended Toredo eggs but apparently they won't live in our cooler waters.

I have looked on ebay but there's nothing there.

Any help appreciated as there are not many jobs to do now and I am nearly ready to launch and feel it would better to get this done before I go cruising (as it may be difficult afterwards).

Many thanks.

You have had your leg well and truly pulled! Both gribble and teredo are aquatic creatures that feed on wood. Gribble chews away at the outer surface of unprotected timber, whereas teredo makes his home in the planking of boats. I have seen teredo tunnels large enough so that I could poke my index finger into them. They are invisible until the plank collapses and the boat sinks. It is because of these creatures that we antifoul our boats. A secondary benefit is that barnacles are discouraged from growing on the boat. Both of these animals will possibly find your your boat without your help.

As well as the gribble and/or teredo you will need a good covering of emulsified engine oil enriched with tincture of diesel, dog hair and galley detrius. If you are going for the workboat ambience I also suggest copious amounts of fish scales.
These essentials are rare and at a premium. However, as encouragement to a newcomer to the forum I will offer up a sufficient amount, gratis.

p.s. bring a bucket, trowel and breathing apparatus.

Re: Gribble, and Teredo

There used to be a fine colony of Gribble in Ramsgate Inner Harbour, but you will find them elsewhere too. They are a small shrimp-type critter. They eat wood but they only tunnel in a little way, so the wood becomes spongy and breaks off. They prefer brackish water.

There was a time when teredo was reckoned to be unlikely in UK waters as they were too cool; having found a sea temperature of 27 deg C. at my mooring in recent summers I now doubt this. It is said that teredo does not eat teak; this is not true and I can show you a specimen of teak that I picked up in Hong Kong harbour that is riddled with teredo on three sides (the fourth side is perfect!)

Come on guys, read the profile, "Enjoying people laughing at the believability of the bollocks I talk". It's us what's 'avin our legs pulled. The oldies are always the best.

You're too sharp milltech

Like a shut razor mostly.

Nice jumper - my mum used to knit them - well toasty in winter but a bit itchy around the neck - but there you go, there's always a balance in whatever one gets up to eh? Back to the jolly old boat now as another summer slips by and the grass grows longer by the day.

Re: Jumper

That was all of 15 years ago, same jumper gets longer every year and would now do good service as a mid winter night shirt, sort of Scots Monk variety, on the grounds that it was purchased in 1990 at Fort Augustus on a transit of the canal.

Here we were "up the road" at Kytra 1990, avatar picture was taken in wheelhouse.

I wonder who you are? With a plastic boat I bet and I reckon it's got two keels?

I fancy you may not have looked at our friend's website ; he looks horribly competent to me!

Re: Gribble, and Teredo

A few months ago, a poster on the forums asked about where old GRP hulls went. I posted, in fun, that polyestermites would chew it to bits if left long enough.

A while later, on another thread, someone posted that polyerstermites would take a hull apart if left alone long enough. Almost word for word. I despair sometimes

 

[castaway]

Just as well you caught this in time, not so readily available these days due lack of demand; however I did spot a box next the the bantam eggs at the 'One stop' in Emsworth.

A light wipe over with Stockholm tar will hold 'em in place until they become established.

Good luck, Nick

Faced with a similar problem I was advised by my boatyard gods to fit a `Gribble Anode`. Similar to a zinc anode but made of unpainted balsa and fitted to the inside of the bilge as a sacrificial feast for the nasties. . . . .
