Feel I have to ask about something that is bothering me sir.
Would it not be possible to beef up the interior surface of the void at the aft end of the keel moulding, say 10-20 layers of csm/woven roven and lashings of resin all consolidated into one solid mass using rollers, if there is space to work down there?
Would this not strenghten the whole thing up?
Or it could also be added to the full length of the underside of the keel like a shod band on a cart wheel, done in stainless steel or grp laminate.
Just because the forward section of the keel is full of ballast doesent mean that water can not get inside the laminate and silently reek havoc over the submersion period.
Just a thought as I like everything Clyde built and as strong as a brick out house.

Gentlemen all,
1. anchor locker drains back to a wee coffer dam in the forecabin. It can get smelly in there, so we don't go, it's like the loft.
2. Steering was done by autopilot, once the Cock of Arran has been rounded it's 118-ish, regardless of what the captain has in his hand.
3. The vigourous tapping of the dolphin's tail did appear to be an attempt at communication, Unfortunately we got our programmes mixed up and asked if Skippy had something to say, Dolly took umbridge and went with the other boat.
4. Once the keel's opened up we'll see what has happened, I'm assured it will be strong by the time they're finished. Personally, I'd like to create a sump within the bilge so I could concentrate the dregs round the pump.

Anyway, this is getting silly - FNS?

Commiserations, but thanks for posting lots of useful stuff about what happened.

It makes me even more glad I have twin cast iron keels as I too have explored the underwater obstructions around our coast & even have several chips in the keels to prove it.

Cleaning her up will be a hard task, but not insurmountable. There is a Centaur in Conway that had failure of a cockpit drain which caused her to sink at her mooring. She was up & about quite quickly & you wouldn't know now that she had ever had a problem.

Very impressed with the faultfinding & repairs - builders' foam, eh? Hmmm, sounds like a good idea. In my Kayaking days, it was de-rigeur to carry Denzo roofing tape & Duct tape for emergency patching during a trip. The Denzo could be applied in the water, the Duct tape required the GRP to be dry but added structural strength.

Bill, just back from Lamlash today , You'll be pleased to know you made front page of the Arran Banner just below news of princess Anne's visit.

Fame at last !
I wrote a wee thankyou note to the good people of Lochranza and I'm told it will be in the Banner on 12th.

That would make those two editions collectors items - betcha didn't get me one!

Kath doesn't seem to think it's good at all, but I'm happy to share a page with HRH any day.



What have I said? - NOT that kind of page....

Thanks for that Ian.
Going slightly tangential; has anybody actually seen the CeeGee using CG99 information ?
We've been registered since 2006, when we came back to UK, but I still get asked all the same questions.( colour,type, size of boat, name address etc.)
I wonder why they didn't give us a unique registration number which we could quote/display(or use MMSI).
In fact MMSI/ATIS seems the answer as the radio will send it, and they would have all the inormation at their fingertips, if not automatically, due to clever computers, which of course are in place, now the centres are to be closed...
There must be someone on here who knows how it's (CG99) actually used. - Anyone?

I spent some money - and suffered some delays in launching - having a repair done to the bottom of Jumblie's encapsulated keel. I'd only run her aground once, when my anchor chain broke in Blackfarland Bay, so I think the damage was caused by two years of life on a drying mooring in Milford Haven.

I was down there over the weekend and met up with the previous owner who told me that when he bought her she had a similar repair after many years of life on a drying mooring in Essex.

I don't plan to run her aground much more, but I think this winter's job is going to be fitting a shoe along teh full length of the bottom of the keel. It's currently a tossup between greenheart oak and stainless steel.

I had a look at the damage to Sahona for the first time today, as I had left all the evidence intact for the insurance assessor.
It seems we had a mishap in a squillion, as the boat has settled bang on the only jaggy thing in a bay of soft sand, as the tide fell.
The poor boat smells like a handfull of wet dogs.
Start cleaning down tomorrow, at least there's a decent sized drain now!

It's the salt water, never really dries out. Get it all flushed out with as much fresh as possible.

Yes that's the plan Ian. Thanks for the Arran Paper by the way.
Sounds like the gearbox may be stuffed, so the engine will no doubt have to come out which will give us access to places that have not seen the light of day since 1978... Just hope there's no-one living down there. (well they'd be drowned by now anyway).

Did you send out a dsc stress signal or a voice call?
I inadvertantly and without knowing sent a dsc stress two years ago while programming in my mmsi on the dsc radio, the cg were on the blower very quickly but they did not know which vessel they were addressing (even though I and HB are registered in the cg99) and to add to the confusion they could not hear my voice reply due to my position, thankfully Gordonmc heard and relayed.
Later I phoned the CCG office and asked why my cg99 details werent to hand.
I was told something to the tune of, a dsc stress alert does not automatically bring up the info on their pc and they would have to manually enter the mmsi to find the vessels details which could take longer than asking over the blower.

The marvels of modern technology, eh?

I'm completely underwhelmed!

Well, you don't have to be a nerdy systems designer to figure out what could/should happen if technology was fully utilised.
As I said earlier, maybe this CG shake-up (if/when it happens) will allow them to implement some good new stuff, which in turn will come into it's own when all of us have got off our bahoochies and invested in our share of the (DSC) technology.

No, Eamon, we didn't use DSC, it doesn't come instinctively to me yet, in fact, the thought never crossed my mind.
I keyed the mike, and the only thought was for a quick answer, which thankfully came.
Also, the kind gentleman on the other end wasted no time in providing a pump, which is all I asked for.
I would guess we "wasted" about 45secs passing info, - lat/long etc but it didn't affect the outcome.

So what I'm really saying here, is the voluntary CG99 excercise superfluous?
Could extra info (like a photo for ease of casualty ID) not be added to the existing MARS database?
