Boats! Every day is different, every job is different. But there are basic guidelines and standards to work to. The fun is seeing how terribly far away from those standards the average boatowner gets… Also it’s every trade in one trade. Electrician, yup. Carpentry, also that. Mechanic? Systems? Welding? Also yes. Some days you do mechanics in the morning and carpentry in the afternoon, on the same job.
