Yacht Survey Photos Hull Design Defects - Part I

Hull Design Defects Part I Photos by David H.Pascoe,Marine Surveyor .Here's a good example of poor design and construction detail.Utilizing a glass over plywood framing system,there are no fillets under the frames or stringers which are butted hard against the hull.This creates hardspots with the propensity for stress cracking.Yacht Survey Online List of All Articles on Boats Hull Design Defects Part I; Hull Design Defects Part II; Surveying Storm Damaged Boats; Surveying Boats with Grid Liners David Pascoe is a second generation marine surveyor in his family who began his surveying career at age 16 as an apprentice in 1965 as the era of wooden boats was drawing to a close.Certified by the National Association Thermal Imaging Sun Coast MarineThe advantage of using a thermal camera is these defects in the integrity of the hull are more easily discovered when surveying a vessel.Once the thermal anomaly has been discovered then we confirm the finding by using other tools such as a GRP 33 brand moisture meter and percussion hammer.

It was not caused by the ordinary action of the wind and waves (see r 7 of the Construction Rules in the First Schedule to the Marine Insurance Act 1906),but by the frequent and violent impacts of a badly designed hull upon an adverse sea.If the defects in design and construction had been the sole cause of the loss,then the THE APPLICATION AND INSPECTION OF MARINEholds and outer hull anti-fouling systems.Figure 1 gives a brief timeline of requirements or recommendations from IMO and IACS.These Guidance Notes start with the basics of the chemistry,and mechanics of corrosion to understand protective coatings as a barrier to corrosion.The coating application process technology and coating inspectionStress Cracks,Finishes and Surface Defects on Boat Mid Certified by the National Association of Marine Surveyors in 1972,he has conducted over 5,000 pre purchase surveys in addition to having conducted hundreds of boating accident investigations,including fires,sinkings,hull failures and machinery failure analysis.
