into interactive 3D models for quick identification of points of interest.
Clear, valuable visual inspection outputs for vessel bottoms
Standard point inspections are the status quo for in-water hull inspections, but only show you a small amount of the full picture down below the surface. Instead, gain a quick and hassle-free tool to survey your entire hull with crisp, clear footage outputs and 3D digital twins of your hull.
Hull and niche areas captured clearly
- Gain clear reports and documentation. Capture hull and niche areas. Retain 3D models for later for comparison over time.

Propellers - Niche Area
How do in-water propeller inspections give value?
- Inspections can catch signs of damage or wear early, before they become serious problems.
- This can include cracks, nicks, or bent blades, which can affect the performance and efficiency of the propeller, as well as increase the risk of failure.
- Visual inspections can identify marine growth or debris that may have accumulated on the propeller, which can also negatively impact its performance.

Hull Inspections
Why are hull inspections important?
- Regular hull inspections are important to identify structural damage, corrosion, excessive fouling, or other issues that may affect the safety and seaworthiness of a vessel.
- By conducting regular inspections, crew and maintenance teams can detect and repair issues early, which can save time and money in the long run.
- Hull inspections are often required by international maritime regulations, as well as individual country biosecurity entites when entering ports.

Sea Chests - Niche Area
Why are sea chest inspections useful?
- Sea chests are responsible for filtering seawater used for various purposes on the ship, such as cooling the engines.
- If sea chests become clogged or damaged, it can lead to reduced performance of the vessel's systems and can potentially cause damage to engines or other equipment.
- Regular inspections can help identify and address any issues before they become serious problems, as well as ensuring compliance with regulations set by maritime organisations and country governments.

Bow Thrusters - Niche Area
Why is it beneficial to inspect your bow thrusters?
- It's useful to regularly inspect bow thrusters, as it allows the early detection of issues such as damage or wear, which could impact the vessel's ability to maneuver efficiently.
- In-water inspections can identify blockages or excessive marine growth that could affect bow thruster performance.
- Small issues can be identified and addressed early before they become bigger problems, helping to ensure the smooth operation of the vessel.
