A test carried out by ADSB on a 16 meter last patrol boat with a composite Kevlar and carbon hull showed excellent results.
The test involved 2 similar boats, one with Sonihull Duo installed and one without. The vessels were left moored up within a few meters of each other for a 4 week period.
After the first week a noticeable difference could be seen. By the end of the 4th week, the results were conclusive. The vessel fitted with Sonihull had little or no growth over the entire hull, while the other vessel was found to have so much growth the vessel struggled to get on plane.
As a result of this test Sonihull will be included in all future standard project specifications.
