The simplest way to restrict data that cruiser has access to apply download filters on their device via Download Parameters in MobileMap. These can be configured manually, or imported along with other settings from a settings file or settings stored within the metadata of a feature service. This is useful when all users are trusted and the main goal is to avoid clutter and reduce download times. Examples of this are when a trusted employee only wants to see cruise data for a specific tree farm. To avoid accidentally modifying data from a tree farm managed by other employees, and to reduce the time to download data, they can apply a download filter to make sure the data from that other tree farms is never downloaded. See MobileMap: Edit Download Parameters for more information on using download parameters. Note that all layers must include appropriate attribute fields and values to enable download parameters to function properly.

Hosted Feature Layer Views are easy to create from a Feature Service, documentation can be found here: https://doc.arcgis.com/en/arcgis-online/manage-data/create-hosted-views.htm . Esri also describes how Hosted Feature Layer Views can be used to provide different views of the data for employees vs. contractors in this blog post: https://www.esri.com/arcgis-blog/products/data-management/mapping/getting-started-with-hosted-feature-layer-views/ . Note that WSG Inventory Management System does not use Web Maps per se, and thus the pattern for implementing Hosted Feature Layer Views is even easiera little less complex than the diagram in the blog post linked above:

Keep in mind that multiple Hosted Feature Layer Views can be created from a single Feature Service, so your implementation may look more like the image below in which data managers have access to all data in the master Feature Service, Cruisers have access to all data that are a part of active cruise projects, and contractors only have access to those data that have been assigned to them or their contracting company.
