Rick I dont know about that,,I have made several trips to lake erie to boat yards,to inquire about gelcoats and glassing and 2 part epoxies,,and woods and such,,I am a hands on and first hand type of guy ,,I got the same answers,,well the can says this or that or that is what the costomer wanted,,I think the old school tradesman have been undercut by corporate greed,,,and it will show sooner than later,guys like lazyjacks dad that done it all by hand ,,took to long ,,,,,we want results now,,,is the attitude,,I think that if one is fortunate enough to learn from a true master,,his reward will pay off ,,but untill people relise that the boats and boatyards now are just for a quick buck,taking advantage of the boat owners niativity,,to put it this way ,,I talked to a guy who bragged about his catalina and said it was the most produced boat ever,if you read through the lines ,,you see a massed produced boat for profit ,,how does this compare to a one off that is built by true craftsman?and heed this ,,nobody does nothing for nothing,,,question ,would you rather have a balsa cord hull ,or a lappstreekwood hullwith a real wood keel and keelson ,or a balsa keel with glass over it,,look at bruno stillman,,lobster boats,,in my day you couldnt give away the balsa keel ,,but the wood keels were it,,,longliner
