"Zip Laps" during glassing

Years ago when sanded finishes were becoming popular we used to do what is called a zip lap glass job.Essentially it went like this:Glass the bottom as normaly done,When it came to the deck we would use two layers but didnt flip the lap under,we would just trim the lap flush with the lower rail.By doing this we eliminated the messy bottom lap line and did’t expose any weave during wet sanding the bottom.Back then we didn’t have “speed sprays”. I am wondering if any body does this anymore?I realize that it probably compromises the strength somewhat but how much?We did a ton of boards like this and I dont recall any problems?Thanks Swaylockians. By the way…are any of you guys Aliens?There are a lot of fancy design theories floating around.

I used the zip lap for hard down railers around 1970 or so. There was a very distinct bottom edge where the lap could be terminated. Haven’t seen it done for quite awhile. aloha, tom

Seems like it would compromise tubelar rail strength I agree with the tubular strength thing.Those old seventies boards were thick and we used 6 ounce glass.A modern shorty with four ounce may have problems.Most of my boards are pretty retro with heavy glass.You are in Hawaii aren’t you?We are on the east coast and board snapping is not a big issue.I’m still thinking about it,thanks for your response.
