We replaced the original fuel tank on Yohelah, our 1984 Baba 40 starting in January of 2003. Sadly, it took until the end of June to finish the job. Well, finish the job enough to hold fuel for vacation starting the first of July. The good news is we immediately took the new, full tanks out the Straits of Juan DeFuca into eight foot swells in the Pacific on our way to Barkley Sound - nothing moved!
