Again, we don't know the make/model which can vary the costs wildly.
But anyway, an approximately 60 ft sailing
ketch, FRG with about a 6 ft
draft could be a
Gulfstar or
Irwin or a half dozen other boats.
In any case, 60 ft of vessel means it probably has a lot of "stuff" in it including a large hp
diesel engine and probably a genset. Ketch rig means a whole additional sail and standing
rigging and running
rigging. Twice the amount of stuff to maintain than a simple
sloop.
30 years old means the "grace period" when things generally will
work for 5 or more years is long gone. So major systems will need
repairs or replacement possibly including standing rigging. The age also brings up the probability of
hull blisters - providing there aren't any
collision or other damage to the
hull.
Rudder, propeller(s), shaft(s), and associated struts and bearings are probably worn if they have not been replaced in the last few years.
Since the sailboat you describe could be similar to my boat which is only less than 10 years older - here is an idea of expenses keeping the boat running and doing periodic "re-fits" for the last decade.
2002 - in
refit - $23,000.00
2003 - shakedown cruising coastal - $21,000.00
2004 - cruising - $9800.00
2005 - cruising and new
sails - $23,000.00
2006 - cruising - $6,000.00
2007 - cruising and
haul out for
paint and
repairs - 12,000.00
2008 - cruising - $9,000.00
2009 - cruising - $8,000.00
2010 - cruising - $8,000.00
2011 - cruising and haul out for
paint and repairs - $12,000.00
So you can see the bigger and older the boat the bigger the bills. The above figures include
marinas (mostly
anchoring when cruising),
fuel,
repair parts and
replacements, and haul-outs. The figures do NOT include personal
food, and personal expenses - only the costs of keeping the boat operating. Of course you can opt to not repair/replace broken stuff and save
money in one year to only double or triple the cost in the next year.
