Partially detached under water plank
My 21'converted double ended Maltese fishing luzzu has a carvel built hull.
For'd of the aft bulkhead a plank just below the waterline has partially detached from some of the side frames.
The wood is red deal 1/2" x 6" and copper nails are used for fixings.
I had a problem with a water leak earlier this year.
Even copious quantities of grease did not stop it.
I did recaulk the whole hull in 2011 with " Black Pudding " and soft cotton.
She is now on her trailer very near my house pending some action.
Last winter I removed all the paint from the inner hull.
The hull was incredibly dry having been exposed to warm dry 30c + wind and sunshine.
It is possible that some of the old congealed paint scrapings got behind the side frames and may have caused this problem when she started to take up.
1)Do I try a re-fix the plank using ss screws then remove and seal the ' old ' nail holes ?
2)Is there a proven method of pressing the plank nearer to the side frame prior to fitting the screws.
Any ideas ?
