If have also had the same problem. I bought a secondhand RAM F8 6.3, and was unaware of this problem. Tried to trim the sail, was unsuccesfull, tried again and then heard a rip: 70 euros of Damage to the mast sleeve. My Max stickers was at 96cm from the trailing edge. It should have been at 83cm.
Here the correct list:
Distance from trailing edge to Max point in the sail:
| Sail Size | VTS Max |
| 5,4 m² | 73 cm |
| 5,8 m² | 80 cm |
| 6,3 m² | 83 cm |
| 6,8 m² | 86 cm |
| 7,3 m² | 89 cm |
| 7,8 m² | 96 cm |
| 8,4 m² | 100 cm |
| 9,0 m² | 103 cm |
| 9,9 m² | 112 cm |
So do you own a North Sails RAM F8.. Check the location of the VTS stickers before rigging.
