This is a "cruisers' forum", so I will add my 2 cents.
A friend with a sister-ship have her cushions all remade in
Seattle for about $2,400.
I had a complete fabric sun cover made for our 46'
cutter last April. This keeps the boat covered while it is
on the hard during the tropical summer
hurricane season. Including the fabric, it cost about 400$US.
We will have all new cushions made this year.
If you are planning to travel, you might wait until you are in a place where labor is very reasonable
price and high-quality craftsmen are grateful for your business. It works well for them and for you.
