Below is a link to the SeaBee strip offsets. Stations are at 12" centers from the bow.
Double layer strip or single layer strip / fiberglass... it matters not.

Also attached is a pic showing the second layer being stapled / epoxied to the first.
Construction is like any other stripper, except for the second strip layer... and no fiberglass of course.
I'll post on water pics, and a durabilty report at a later date.

Thanks to all for your comments.
