Thank you for you forum question!
The ArcGIS Maritime Charting Solution provides an INT1 style file. More importantly the solution includes the logic to apply the symbology to features according to the INT1 specification based on a rich set of criteria. If you would like to discuss further and can provide some more background we may be able to provide you with the INT1 style. Please feel free to contact me directly with a private message and I will be glad to put you in touch with the correct people.
Thanks!
Geoff
