Not Actually Me
The new seals were slid down from the top.Hmmm. I'm guessing you're evading my questions because you don't know/trust me. Or, you are one of those chaps with a diametrically opposed skillset to mine, and can't/won't answer.....? If it helps, I'm hopeless at at least half of the things you do well. Probably more. I do know how to fix boats in third-world countries though, and I concede that you do other, different, worthwhile things too. If we all knew the same shit life would be interminably dull.
Completely understand your reluctance to doubt a builder that has a rep like HR. On the other hand, I have worked under other 'high rep' builders, so know how the shit goes down. If the drawing you posted is the full extent of the info HR supplied, I am both saddened and unsurprised. Boatbuilders are funny fuckers.
Hope you get both short and long term solutions, nonetheless.
