1991 Shannon

Pedigree & Construction Unlike mass-production trawlers of this era, Hull #5 carries the NHN manufacturer code, certifying its origin from Walt Schulz’s semi-custom yard in Bristol, RI. The build quality mirrors the world-renowned Shannon sailboats—featuring a composite core construction for superior strength-to-weight ratio and insulation. This is not a "production boat"; it is a boutique yacht built to bluewater standards.

Performance Schulz dubbed this design a "Powerball"—a unique hull form that defies the slow-trawler stereotype. While she offers the classic lines and fuel efficiency of a trawler at displacement speeds, her patented hull design generates lift aft, allowing her to plane and cruise at 12–15+ knots when needed. She tracks straight, handles following seas with the grace of a sailboat, and eliminates the "wallowing" often associated with traditional trawlers.

The Ideal Owner This vessel is perfect for the discerning yachtsman who appreciates the teak joinery, bronze hardware, and over-engineered systems typical of a high-end sailboat, but desires the climate-controlled helm and extended cruising range of a trawler. A true collector’s item for those who understand the Shannon difference.

⚡ Upgraded Solar & Power System – Turnkey for Off-Grid Cruising

This boat is equipped with a professionally installed, high-end Victron Energy solar and power management system, making it ideal for extended cruising, liveaboard life, or off-grid adventures.

The system features four 390W solar panels (1,560W total) mounted on the bimini, paired with premium Victron components throughout for reliable, efficient power generation and monitoring. A Victron MultiPlus II inverter/charger, Cerbo GX control system, smart shunt, and MPPT charge controllers allow full system visibility and intelligent power management from anywhere onboard.

Additional upgrades include:

• Victron DC-DC charger for charging while underway
• Heavy-duty marine wiring, bus bars, fusing, and disconnects
• Properly sized battery cabling and safety components
• Solar disconnects and monitoring integration
• Clean, professional installation designed for long-term reliability

This setup dramatically reduces generator runtime, supports modern onboard living, and is perfectly suited for cruising, anchoring out, or full-time living aboard.

Perfect for buyers looking for a capable, self-sufficient cruising vessel with a modern electrical system already dialed in.

Power: Twin Peninsular 400TA-310 (310 HP each)

The "American Iron" Advantage: Based on the legendary GM 6.5L "Optimizer" V8 diesel block (widely used in military Humvees), these engines offer a unique combination of high torque, low weight, and parts availability that heavier European or industrial diesels cannot match.

Power-to-Weight Ratio: Significantly lighter than comparable Caterpillar or Detroit diesels of this era. This reduced weight allows the Voyager 36’s "Powerball" hull to plane easily and achieve efficient 20+ knot cruising speeds without needing massive horsepower.

Easy Serviceability: Because they share a block with millions of GM trucks and military vehicles, core internal parts, starters, sensors, and gaskets are widely available at standard automotive parts retailers, avoiding the "marine premium" and long lead times of imported engine parts.

Efficiency: Capable of a miserly 3-4 GPH (combined) at trawler speeds (7-8 knots), or a fast cruise of 18-20 knots when you need to outrun weather.
