Kodad probably got the 15-20% number from one of my posts, which is what I generally recommend be held aside for refitting, upgrading, repairing a boat you buy. However, in preparation for a bluewater voyage, this number needs to go up. Long distance voyaging requires additional spares and equipment that coastal cruising does not. The numbers I suggested also didn't include PROVISIONING the boat, just commissioning it.
As for a 20-30 year old boat... if it is in good shape, shouldn't be a problem. The thing to watch out for is many 20-30 year old boats are now at the point where major systems need to be replaced, like the standing
rigging, and if this hasn't been done, it is an expensive proposition and should be figured into your costs.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
