And this one&#39;s from Tammie Norie

<p>
 And the moral of the story.......Stainless steel, even A4/316 grade is not a trustworthy material below water. Crevice corrosion can occurs in oxygen depleted areas with these sorts of results. Be aware and be prepared!

		<title><![CDATA[Tammie Norrie Dried Out in Totnes]]></title>
		<description><![CDATA[<p>

Here&#39;s Tammie Norie &#39;On the Wall&#39; in Totnes, 2009
</p>
<p>
<font face="Arial" size="2">This was the first time we ever tried drying out so there was a good deal of nail-biting involved but all went well; although sleeping head down is unpleasant. The requisite &#39;lean-in&#39; was obtained by piling the anchor and some chain on the side deck. Also the weight of the anxious crew helped. I did consider running a line ashore from the mast but, as the quay is a public right-of-way, I could not risk tripping up the dog-walkers and promenaders. A few old fender planks are available on the quay but there are no other facilities that I could find. Ten minutes walk brings one into the picturesque town of Totnes, with plenty to interest and refresh the visiting ditch-crawler! I believe it is possible to berth on the other (West) side of the river at a boatyard which has showers but we arrived after it had closed for the day. In any case, I read in the local rag that that area is going to be re-developed before long.</font>

</p>
<p>
<font size="3">The two top fastenings are machine screws fixed through the deck &#39;upstand&#39; from inboard into tapped holes on the stem fitting. The remainder are machine screws, normally tapped into the GRP though some may have &#39;helicoil&#39; or similar inserts. Some boats may have had a long &#39;through&#39; bolt fitted through the bottom of the stem fitting on the centreline with a large &#39;back-up&#39; washer and nut inside the forepeak.</font>

<font face="Arial" size="2"><u>Lazerette Hatch - Stern Deck</u></font>

<div>
<font face="Arial" size="2">I&#39;ve also had the GRP expert at my yard put in the lazarette hatch on the stern deck which seems a great success. The new hatch was much lighter than the GRP that was removed, although building up a surround to make a level playing field made it &#39;even steven&#39;</font>
