2025 Eastern 998 – Extended to 35' LOA by JC Boats – Tournament-Winning, Fully Equipped Downeast Originally built as a 31’ Casco Bay, this Eastern 998 underwent a professional 3.5’ hull extension in 2017 performed by Jack Caddario of JC Boats, the original Eastern hull builder. The modification was fully documented, and the vessel was federally re-documented post-conversion. The result is a significantly more capable 35’ Downeast with a stable, efficient running surface and excellent offshore pedigree. The boat has been surveyed in 2025, 2022, and 2017, with hull construction featuring Airex core and Airex C70-40 (carbon fiber strand) reinforcement in the cockpit area. Hullsides have been sounded inside and out and found dry and structurally solid. While some cosmetic refinishing is optional for the next owner, the vessel is mechanically strong, well-outfitted, and turnkey for serious fishing or mixed family use.
