Taking on a project boat means devoting the time to both do the work and learn how to do the work, because paying professionals to do it will soon cost more than the boat is worth. If you can find guidance as to how to remove this teak and how to refinish the boat in plain
aluminum, then ask yourself whether you are ready to take on the tasks. Recognize that the job will take several times the time budgeted in the beginning, and several times the expense, even with the labor being your time. Save the professionals either for specialty jobs that need another level of skill (I got the outer seams of my boat professionally welded), or as advisors in a
DIY yard. I did get to know one airline pilot who could either fly to pay the professionals or do the work, even
trade, but he gave up on the project after three years.
Just looking at the outside of this boat suggests that you have more projects ahead of you than removing the teak. How about listing all the jobs, and thinking though cost and time for each?
Are you ready to give up cruising for a long time? Would you be better off with a lesser boat that is ready to sail? Would it be better to
budget how much the project will cost and finance a similar boat that is ready to sail?
