You haven't told us about your experience at all, forgive me if I get too basic, and this will be only a partial list.
In my opinion, ALL sales should be made contingent upon the vessel passing her sea trials; and insist on sailing it, as well, not just a 1/2 hour motor
around the harbor.
Beyond that, after 5 years on the hard, many seals
are likely to not function properly, so you're going to want to understand the situations where fuel
and water go. If it has a "dripless" coupling, it probably shall have taken a "set" and need to be replaced.
The rig is 5 yrs. older. If total age on the rigging
is 10 yrs. or more, replace all of it, and figure in those costs to the purchase price
. The running rigging
has been sitting out there, too, ageing. How old are the sails
Look for "water tracks" where ports
or hatches may have leaked.
Check the engine oil
level, and condition; check its other fluid levels. Smell the ATF in the transmission
for scorched smell, if it smells scorched, you may soon be replacing the tranny. Pay to have an engine oil
analysis done. Look for signs of fuel leaks
in the past, or signs of fuel leaks
recently having been cleaned up. Find out whether the injectors have been serviced, and when. Check the fuel tanks
for gelatinous "stuff", as if they didn't use biocide, you may need to have the fuel "polished", and the tanks
cleaned. Enquire into cost of same. (I don't know how difficult it is in that boat to access them.)
The replacement of an engine is always a big hit to the wallet. Do NOT buy the boat without driving the boat around under its own power. Let your partner be on the helm
while you go look at the engine while it is running. Are there leaks? How about oil under the engine? You're a detective, looking for what isn't there as well as understanding what you do see. I'd suggest taking a flashlight or a head
lamp for seeing in all those dark spaces. Besides spider webs, you may see signs of leaks or other problems. ;-) Actually, if you have a friend who is marine diesel
savvy, and it's not your strong suit, bring him or her along, too, for help.
If your surveyor
doesn't do rigs, hire a rigger to survey
You would also want to know about the osmotic blister situation as some of the HC's had blister problems.
Well, that should give you some food
for thought. I'm sure others more knowledgeable than myself will have useful input for you.
