Description

This is not your typical 48’ Viking. Extensively refit and upgraded by a knowledgeable owner over the years, this vessel has been transformed into a serious offshore fishing platform with modern systems, structural enhancements, and a clean, updated interior. She offers the ride and build quality of a classic Viking, paired with the reliability and functionality of a much newer boat. If you’re searching for a sportfishing vessel that offers all you need for long trips offshore as well as the comfort to liveaboard on your weekends off, this boat deserves your attention. She’s equally suited for weekend cruising, overnights, or extended fishing trips.
Repowered and re-engineered for dependable offshore use, this Viking is built to run. The CAT C8.7s deliver efficient cruising power, while extensive system upgrades—including fuel lines, steering system, exhaust, engine room upgrades, and wiring—provide confidence rarely found in a vessel of this vintage. The custom mezanine seating, cockpit grill, and upgraded ladder make the cockpit layout fantastic for both hanging out at the dock and offshore fishing alike. The interior presents much newer than its age thanks to tasteful upgrades to give the interior a more modern look and feel. The salon was recently refinished, clan galley, reliable AC systems, updated plumbing, and the list goes on.
Key Highlights:
- Twin CAT C8.7 Diesels (650HP each) – installed 2014
- New Generator (2024)
- 680 Gallon Fuel Capacity – ideal for canyon and long-range runs

Construction and Structural Upgrades:
Where this boat truly stands out is in her structural integrity and investment below the surface:
- Engine room bulkhead modified and stringers reinforced during repower
- Deck-to-stringer tie-ins redone for added strength
- Chine rails added and reinforced with multi-layer glass into hull
- Exhaust system rebuilt and reglassed to solid glass
- Superstructure reinforced with vertical supports
- New windows, trims, and reglassed anchor locker
- Professional fiberglass work completed where needed
This is a heavily upgraded, reinforced Viking built to handle offshore conditions.
This 48’ Viking represents a rare opportunity to own a fully sorted, extensively upgraded convertible without the price tag of a newer boat. She has been continuously improved, properly maintained, and intelligently upgraded in all the right areas.
A lot of boat for the money, and unlike any other 48’ Viking on the market.
