The Friday before our scheduled Monday morning survey, we had the boatyard schedule the boat for the last haul of the day - a shorthaul, left on slings. This enabled the hull to dry out for at least two days. Not ideal for moisture meter readings, since it takes weeks for a hull to fully dry out, but certainly better than an hours time "during lunch".
As it turned out, they put in on stands & blocks, charging us only for a shorthaul. This was even better for our surveyor to reach areas otherwise covered by slings.
