I have a 36ft 1969 Harborough Marine, recently bought with a full hull overplating job carried out four years ago. On buying the boat, I noticed a considerate diesel / oil smell but thought a good clean and a switch to mooring mains power (a genny was used previously) would do the trick in getting rid of the smell...general fumes.
It turns out (unfortunately) that the source of the smell is a combination of an old engine oil leak and bilge water that has crept up the length of the hull, between the old hill and the new overplating. Basically, the old hull has rotted away and what lies beneath the ballast is combo of old hull, mud, bilge, condensation and a lot of oil. Loverly!
The new hull beneath is sound - surveyed etc. I am currently removing the old hull by hand (yes, it is a truly dirty job), but I have some questions that I hope the forum could help with:
Do you know of any good products for breaking down oil / cleaning? Also to get rid of the smell?
Is this a job anyone else has carried out? Any tips?
Is the old hull normally removed when overplating is carried out?
Where, typically, are the points where the new hull is welded to the old infrastructure? Should I be careful when scraping away!!
Am I mad to do this?
Should I be concerned about the weight that is coming off the boay by removing the old hull?
Is there normally a plate / barrier across the beam of the hull between the (trad) engine housing and the rest of the cabin, or should bilge be able to pass up the length of the boat
Any tips on disposing of oily water? I want to avoid tipping it down the drain!
So many questions, such little time (-:
