Problems of this sort are always worse than one's hopes. You do not want to be on the receiving end of an ongoing revelation of more problems after you have bought the boat.
It seems from your original questions that the boat is still in the water
. You should insist, at the current
owner's expense, that the boat be hauled to carefully inspect for damage to the keel
, and hull
structure If he refuses, that's all you need to know. He's looking for a buyer who is in love with the idea of sailing, not the reality of the costs. Take your money
This could be a totally non-issue.
Or it could be very serious.
We don't and can't know.
Too little information.
How deep is the crack?
surface? May be only a minor issue.
Through laminate due to excess flexure. Bigger issue.
Is there moisture ingress to a wood core
. Bigger issue.
Is there rotted core
. Biggest issue.
Many engines will suffer from harmonic vibration at specific RPMs.
How severe is it?
Slight vibration noticed at specific RPM
. May be no issue.
Heavy vibration at specific RPM
. May be a minor issue.
is trying to jump off the mounts. May be a bigger issue.
This could be a US$250K boat.
First of all, who did the survey
Always hire a a proper SAMs or NAMs certified surveyor
if you are truly serious about the boat.
The number of "THE SKY IS FALLING" responses are ridiculous.
If you "RUN AWAY" from every boat that has any issues, you will never buy a boat.
Every boat, even brand new ones, have issues.
If you like the boat, think it is a good deal, and want to own it, call in the proper "qualified and certified" surveyors.
