tony, i have Kolbes Long Term Almanac 2000-2050 laminated and spiral bound together with haversine table (to 0.1´) and quad of laminated all haversine longhand doniol "forms" (if one sand surface carefully with 600grit pencil will work ok) and just to be certain the instructions for all haversine sightreduction.
Each page laminated in such a way that no hole is cut in the paper (actually about 5mm of clear laminate between paper and hole). all bound in same bundle, quite a stack but waterproof as i could get it.
actuallt have had one similar page under water ~3m deep - for about 2 weeks with no real damage, algae growtn and matte surface (likely sand abration from currents) and one corner starting to delaminate...
