i hav owned a few canoes and used a few otherswhat i found is that poly canoes are softer and more flexable they do scratch underneath but they are easyto portage[carry or drag] over rocks or other ground due to them being lightand because they flex dont crack or split when droped or ramed into rocks or logs as well as being uv stable fiberglass will crack split it is brittle over time will break down with uv it is easy to damage and is heavyto portage but can be easily repaired witha fiberglass repair kit whic can be carried with you or for onsite bandaids a tube of silicon will seal cracks and when you get home clean it off and repair it properly silicon will also bandaid poly if it ever does wear through but needs to be plasticwelded as silicon will eventualy lift free whish ever way you go canoes and unfished water go together [GOODOO]
