Not exactly. You are only committed if your offer is accepted.
I think that the premise is that you negotiate to what you are willing to pay to get that boat. If it needs repairs to make it serviceable, you will deduct those costs from your agreed price. (Of course some more bargaining will go on.)
If you were offering asking price, then I would agree with you, but I think most people bargain down.
Why go through the expense of a survey if your offer is not a sure thing?
