Novice Sailors buying boat
You only asked half of the question. The other side of it is whether, as newcomers, it makes sense to accept ownership of an older, larger boat. I think that''s a far more critical issue than learning to sail on the boat, which can be easily done with the help of friends, an instructor or on your own...or a combo of the above.
The level of maintenance, replacement and upgrading needed on a 30 year old boat is not for a novice IMO.
