  1. No - not bought it yet - sitting on the fence until I know for sure what the risks are and what the bill is likely to be. Any suggestions for a suitable place to get the work done? Ideally south of Birmingham, closer to London or even Gloucester would be best. Thanks again - all of you.
  2. I have to say it looks to my untrained eye like the same thing, just not in such an advanced state. The entire centre section of the baseplate I looked at yesterday was covered in very similar 'growths'. My state of depression is deepening. Will hit the phone now to sound out local boatyards.
  3. Good point well made - I just assumed this was likely with it being a 'domestic' mooring.
  4. Wow - thank you all for such a quick and detailed response. First - a confession - I did not employ the services of a surveyor, being an engineer myself, so did all the visual inspection and measurements. Probably not my best call to date but there we are. Subsequent discussion with a surveyor suggested this was quite a common occurence - plenty of thickness left! A little more history - first, I understand the boat has been moored for its entire life at an end-of-garden morring near Kidderminster - this would make it River Severn I assume. It has cruised of course but the majority of the time it will have been 'at home'. I also assume it will have had a shoreline connected for most of that time - no solar panels so shore power only. I have yet to see a GI on the boat. My thoughts at this stage are a combination of the presence of the shoreline and the absence of anodes through the centre section of the hull - but this is supposition, hence my shout out. The boat hasn't been lifted for 5 years, since it was shot blast and received 2-pack epoxy to the hull sides - this has stood up well but has a small number of breakthrough points from physical damage - nothing serious and certainly nothing like the attack to the baseplate. The edge of the chine is the first place to show any colour, with rusty looking 'bubbles' - picture attached (I hope). Underneath is a different story as the attached pictures will show. Thickness measurements showed 9.5 to 10mm generally. The depressions don't look like impact damage or distrortion, simply hollowed out areas where the [late is thinned. As you can see, they are smooth sided and look just like finger tip and thumb prints in rolled out pastry. The crust was fairly thick in places, maybe 3 or 4mm and was black against the steel. You can see where I have scraped off varying size sections of it. The pictures are obviously upside down due to my position! I note the comments above on MIC and hesitate to acknowledge the orange growths I saw. Your comments are invaluable - thanks.
  5. Hi all - I'm hoping you can share some wisdom with me. Situation is that we are in process of buying our first boat and have found 'the one' we both like! 2008 Piper hull, 57 feet and standard 10/6/5/4 build. The boat has not had a lot of use in recent years and was out of water today for a hull inspection. I was quite disturbed to find, underneath the accumulated crust, many large 'depressions' in the base plate steel. While the surrounding plate measured at 9.5 to 10mm, the depressions were up to 2.7mm deep and anything from 10 to 25mm dia. They are smooth depressions rather than sharp edged pits and are all over the central (bow to stern) area of the baseplate, everywhere I looked, while the bow and stern areas are not so bad. There are anodes fitted bow and stern but nowhere else. No evidence that the base has ever been blacked. The only other observation is that the water film betwenn the crust and the plate was black - very black, almost-like-ink black. So, my questions are:- what do you think may have caused the corrosion/erosion? do you consider blacking or 2-pack epoxy will stop it in its tracks? should we walk away and look some more or are we likely to find this is common? Thanks for reading this far! I hope you can help me.
