På ritningarna står skrivet att det är en internationell 8 meters jakt. Som Tapani Koskela påpekar är detta troligen fel eftersom Isolde är en 8 meters cruiser/racer. Hans motivering:
"Why the drawings of the year 1951 suggest a "8 m Int. Yacht" is unclear. Only the second, modified sail plan from 1955 has the characters "CR 8" added on top of everything else.
However, there are two important facts. Firstly, the drawings of 1951 were published as a Cruiser/Racer in 1954 or the year the yacht was finally launched. If you carefully look at the drawings published in 1954 you will notice that they are exactly the same as those of the year 1951.
Secondly, the dimensions of the yacht were too small to ever make it an 8mR."
