1. Coastal Surveillance Systems: Implementing advanced surveillance systems along the coastline helps detect small boat movements, enabling timely response [[1](https://en.wikipedia.org/wiki/Naval_tactics)].
2. Guarded Ports and Harbors: Securing ports and harbors with physical barriers, such as booms or nets, can deter or hinder small boat intrusions [[2](https://www.britannica.com/topic/naval-warfare/Tactics-in-the-modern-era)].
3. Amphibious Barriers: Deploying barriers in shallow waters, like anti-landing obstacles or underwater structures, can impede small boat landings during invasion attempts [[3](https://en.wikipedia.org/wiki/Amphibious_warfare)].
4. Strategic Lighting: Illuminating coastlines during nighttime can enhance visibility, discouraging covert small boat approaches.
5. Community Vigilance: Encouraging local communities to report suspicious activities along the coast helps maintain a collective defense against small boat infiltrations.
