I had a 45 and now have a 47 ,the seat
cushions are identical. I have just had a new back rest cushion and seat cushion made by the guys who have made them for the past 13 years.
Or are you referring to the
saloon cushions , they too are different . The 45 has an oval table with seats that wrap around it. The 47 is not the same.
Google the layout of the 45 and 47 to see the difference.
There were a few
boats , private ones that did not like the sausage type on the
charter boats , so Joe in
Cape Town made flat back cushions..these will not fit the 45 as the design of the bases is not the same.
