I would be hesitant in making too much noise
or being too big of a PITA.
In several dealings with yard owners and managers I have found the vast majority to be pretty easy to deal with up until someone starts being a nuisance.
They have you over a barrel. If you are paying a daily fee for the yard I have seen them go from very friendly to downright becoming aholes, the longer the boat stays the more they make, the more noise
you make they start considering the daily fee your cost for being a PITA.
And I have seen an instance where the owner suddenly found his unfinished boat in the travel lift, bungs pounded into the thru-hulls and being dropped back into the water. This was after the owner of the boat threatened to sue the yard for not finishing a job.
Not sure how the lawsuit came out, if it ever did, but I do know that the boat sat chained to a dock
in the water at the boatyard for a couple of months without benefit of a finished bottom before it was finally brought back into the yard and finished.
Find out what the yard managers or owners favorite drink/food/or other vices. In one instance a case of scotch to the yard manager suddenly moved a boat from the end of the line with no one finishing the job, to a boat that was out of the yard in a matter of a couple of days.
Just make sure you are dealing with the yard manager or owner and not one of the workers.
The bottom line is to carefully read the agreement that you signed to have the boat hauled and blocked and any work to be done. If you are having the yard do the work make sure you have a anticipated/scheduled completion date that the yard signs off on. Then depending on the location/state/country you have a signed doc that most yards will do their best to adhere to. If at all possible you should also stipulate in writing (that the yard signs/initials) that you are only paying for lay days where work is being done on the boat, no work, no charge for that day.
There used to be a couple of yards in this area that were notorious for these types of shenanigans, happily they are no more, sadly they were replaced with dockominiums and condos.
