EPA Grant Project Hull Testing Efforts in Full Swing

Wednesday, 22 July 2009

The Port is underway in Phase two of its EPA Grant Project - testing alternative paints on boat hulls. Starting in April, ten of the top performing paints identified in the panel tests were applied to boat hulls. Currently there are 12 boats participating in the study, two boats are included as duplicates. 

The paint application process was a success - largely in part to the efforts and contributions  of our local boatyards. The Project Team increased their understanding of the hull paint application process. A highlight of this was having the opportunity to see some new stripping technologies. Additionally, we gained valuable insight into how tie coats, primers, and painting techniques, such as spraying and rolling factor into the overall cost of the alternative paints.  

Inspections and cleaning (when needed) are occurring on a three-week frequency. We are following our field assessment protocol to determine when a boat requires cleaning and it seems to be working well. While it is still early in the testing, most of the paints are performing well. Some are able to go several weeks without needing to be cleaned. Other paints are requiring regular cleaning. The Project Team is getting a better understanding of how each paint works and we are able to see unique characteristics within each paint. In general, when cleaning is required, the hand cleaning tools have been successful in removing the fouling with reasonable effort.

The Port is also tracking boat use as a part of this study. The participating boaters are logging the dates, speed and duration of their trips over the course of the study. This information will be factored into the performance profile for each paint. 

The annotated outline for the EPA-funded "Safer Alternatives to Copper Antifouling Paints" final project report is now available for viewing. Click here to view the annotated outline.

The purpose of the annotated outline is to provide you some insight into what information will be presented in the report, and allow you an opportunity for stakeholder input on the development of the report. We are interested in receiving input from you on the attached annotated outline.

We are accepting comments on the annotated outline until 5:00 PM on Wednesday, September 8, 2010.

The Project Team is continuing to gather information on coating performance for the final report. We are currently aiming to provide a draft final report for stakeholder input by the end of the year.
