SeaPiper 35 Narrow-Beam Long-Range Cruiser
From 2018
The SeaPiper 35 is an unusually narrow long-range pilothouse cruiser designed around an 8 ft 6 in beam, shallow draft and single 85 hp diesel. Its light-commercial aesthetic, separated cockpit/pilothouse/forward-accommodation zones and substantial tankage prioritize efficient low-speed travel and easy berth access over conventional yacht styling.

Best for
- Couples prioritizing range, narrow beam and efficient inland/coastal cruising
- Owners who value simple workboat-inspired systems and protected pilothouse operation
- Routes where slip width or bridge clearance matters
Trade-offs
- Narrow beam limits interior width and form stability compared with beamy trawlers
- Cruising speed is approximately 7–9 knots
- Distinctive utilitarian layout may not suit buyers wanting one open continuous salon
Known concerns
- No model-specific concern has been promoted to B-Atlas’s evidence threshold. This does not mean the model has no age-, condition- or hull-specific risks.
Inspection focus
- Verify hull-specific build specification and any production changes
- Inspect aluminum/stainless fittings, windows, sliding doors and deck penetrations
- Inspect Beta diesel cooling, exhaust, shaft, rudder and fuel systems
- Verify tank installation, fuel transfer and sanitation systems
- Test electrical, inverter/charging and optional comfort systems
