Cape Dory 30
If your purchase contract stimpulates that the sale is contingent on a survey and that the survey demonstrates the boat is fundamentlally in the condition it has been represented, and if that''s not true, then you can simply request your deposit be refunded.
The legal stuff aside, you would not be buying a boat but rather a ''project'', and one of the main attractions you originally had to the boat - a good financial decision - just went out the window along with the keel crack.
You don''t need to justify your decision to the broker or ''satisfy'' him about your logic; simply saying ''no thanks'' is sufficient. But if you choose, you can point out that the next survey - when it''s time for you to sell the boat - may produce a similar blemished report (i.e. a hull repair was required)...and why would you knowingly purchase that grief?
Sorry to hear about the surprise, but aren''t you glad you had her surveyed!?
