Certified Marine Surveyor




Though many years of working with composite hulls, I have developed considerable expertise in the analysis and correction of osmotic blister problems.

Osmotic blistering of fiberglass composite hulls which may result from the construction process is aggravated by water pollution, temperature, and length of time between haulings.

I can help you to determine the extent of the problem, whether it is a minor surface or structural condition and to develop a plan for repair and/or preventive maintenance.

My experience in monitoring manufacturing processes, repair methods and cost, and assessment of the extent of the problem in your own vessel or a vessel you are thinking of purchasing. We understand moisture, fiberglass lay up, current diagnostic techniques, non-destructive testing, core sampling, and laboratory analysis.

I was named one of the “Top Warriors in the Blister Battle” in “Hull Blisters: Know the Enemy”, Rick Strand, Practical Sailor, July 15, 2001.
