Post #5.As long as you prevent any buyer's expenses involved with the survey from attaching to the boat, their is little recourse against the deposit. While I've never heard of it happening, damage due to negligence, done to the boat during a survey, might be a good reason to want a standard deposit.
The party that most wants to see the deposit is the broker, who also signs the contract. They get paid out of the deposit money in certain defaults.
Your post was written as if you actually posted the contract, but I didn't see it. Wondering if my popup/ad blocker is preventing it. I was curious, because I just signed one last Fall and it clearly states a copyright violation for use my a non-YBAA member. They are updated routinely too. The one I signed in 2018 was materially different.
