What are the major differences between the 1801 and 18SE? Had a 2018 1801....good, roomy, durable boat. If you do a search you will find some of the modifications made to my 1801. Good Luck with the new boat! Also from South Jersey.Hello My name is Clayton Kelly I'm from South Jersey. I have a Parker 18se being built and will be completed next month. Looking forward to sharing with the forum.
