How Old is Too Old When Buying a Yacht?

[Captain Crisp]

My Twister's 2 years older than me...
Both a bit leaky round the stern gland, but she sails like a dream!

My vivacity was 1969 and the grp was fine aside from lots of holes cut and drilled by previous owners. Someone had painted it but under that the surface was fine from what I could tell. Modern grp is generally better and won’t get osmosis.
I’m expecting my GRP garage roof to outlast thegarage and would say you’d expect 100 years

Does anyone know how long GRP lasts? Appreciate it's a bit of a case-by-case question.

The short answer is no. When considering the vast number of unwanted, undisposable boats the answer might be "Too long"

After one million stress cycles the strength of GRP is reduced by half (D. Gerr, Boat Strength). This is happily countered by the ridiculously over-built hulls on many of the older designs. Ours, as I found out when I put in a new transducer, is 0.75" thick.

Apparently, I'm 182. Can i get my pension back-dated, please?

Your calculation seems grave -ly in error

My boat is 41 yrs old and it's perfect for us, Moody 33mk2, gradually upgraded over the years. New engine fitted courtesy of an unexpected legacy soon after I purchased it. I do enjoy upgrading and maintenance and sailing of course (when allowed!) Perfect boat!

The first GRP glider was the Bolköw Phoenix, in the late fifties, and to the best of my knowledge they still have certificates of airworthiness. They are built like tanks - much, much heavier than modern gliders - but being aircraft they get very detailed inspections at yearly intervals or less, so any issues would almost certainly have shown up.
