The Whip 17 stands as a testament to the Molded Fiber Glass (MFG) Boat Company’s transition from high-volume powerboat production into the competitive recreational sailing market of the 1970s. Produced under the SailMFG brand, the Whip 17 was designed to capture the "family daysailer" demographic—sailors who prioritized stability and ease of trailering over raw racing speed. Built using the same high-pressure fiberglass molding techniques that MFG pioneered for the automotive industry, the Whip 17 features a robust, thick-walled hull that has allowed many units to survive in sailable condition decades after production ceased. Measuring 17 feet in length with a generous beam, the boat was positioned as a larger, more comfortable alternative to the company’s popular Sidewinder and Bandit models.

Sailing Performance & Handling
The Whip 17 is characterized by its "big boat" feel within a small footprint. With a beam approaching seven feet, the hull offers significant initial stability, making it an ideal platform for teaching novices or sailing with young children who might be intimidated by the "tippy" nature of narrower dinghies. Its displacement-to-length ratio suggests a hull designed for cruising rather than planing; while it can move efficiently in a breeze, it is not intended to compete with high-performance skiffs.
The boat utilizes a retractable centerboard, which significantly reduces draft for beaching or shallow-water exploration, a feature often noted in early SailMFG marketing materials for the model's versatility. On the helm, the Whip 17 is generally described as forgiving. It lacks the twitchy responsiveness of the Sidewinder, instead offering a predictable, steady motion through a chop. The fractional sloop rig provides enough sail area to keep the boat moving in light air, though the weight of the hand-laid fiberglass hull means it requires a decent breeze to truly come alive. Owners often comment on the boat's ability to remain dry in moderate conditions thanks to its high freeboard and flared bow.
Interior Comfort & Variations
Unlike the open-cockpit "beach boats" in the SailMFG lineup, the Whip 17 features a cuddy cabin that differentiates it as a true pocket cruiser. While the boat is too small for standing headroom, the cuddy provides a protected area for gear storage, a portable head, or a dry retreat for children. The cabin typically features two modest V-berths, though these are more suited for "nap-sailing" or emergency overnighting than extended cruising.
The cockpit is the primary living space, designed to accommodate four to five adults comfortably on bench seats that run deep into the stern. In terms of variations, the Whip 17 shared its production era with the SailMFG Bandit 15 and the Copperhead; while these smaller siblings were strictly day-boats, the Whip 17 was the "luxury" option in the fleet, often finished with more substantial hardware and occasional wood trim accents that gave it a more traditional aesthetic than the more "plastic" look of the smaller Sidewinders.
Known Issues & Buyer’s Checklist
Prospective buyers of a Whip 17 should prioritize an inspection of the fiberglass integrity and specialized hardware, given that SailMFG-specific parts have been out of production for nearly forty years.
- Centerboard Trunk and Pivot: Like many vintage centerboarders, the pivot pin and the trunk itself are prone to wear. Check for stress cracks around the top of the trunk inside the cockpit and ensure the board operates smoothly without "clunking," which indicates a worn pin or hole.
- Transom Stress: If the boat has been used with a small outboard motor (a common addition), inspect the transom for spider-web cracking or flexing. The original fiberglass was thick, but decades of engine vibration can soften the core.
- Mast Step Compression: The Whip 17 uses a deck-mounted mast. Over time, the support structure beneath the deck can compress or rot if water has intruded into the core. Look for a "depression" or dip in the deck around the mast base.
- Gelcoat Oxidation: MFG boats were known for bold 1970s colors (often yellows and blues). Due to the age and the specific resins used at the time, heavy oxidation is common. While usually cosmetic, deep chalking may require professional buffing or painting to restore.
Community & Resources
While there is no longer a formal manufacturer-backed association, the Whip 17 is supported by a dedicated community of MFG enthusiasts. The "MFG Boat Club" and various vintage fiberglass boat forums serve as the primary repositories for technical manuals and restoration advice. Because MFG shared many manufacturing techniques with the Corvette and other industrial products, technical enthusiasts often look to specialized composite forums for advice on structural repairs unique to the Molded Fiber Glass process.
The Verdict
The Whip 17 is a rugged, stable, and approachable pocket cruiser that offers a low-cost entry point into sailing. While it lacks the pedigree of an O'Day or a Boston Whaler Harpoon, its industrial-grade construction makes it a survivor.
Pros:
- Exceptional Stability: The wide beam and hull shape make it very difficult to capsize under normal conditions.
- Dry Ride: Higher freeboard than most 17-footers keeps the crew comfortable in a chop.
- Versatility: The combination of a cuddy cabin and a retractable centerboard allows for both overnight camping and shallow-water beaching.
Cons:
- Weight: Heavier than many modern 17-footers, making it more demanding to launch and retrieve single-handedly.
- Limited Performance: Not a boat for those seeking high-speed thrills or competitive racing.
- Parts Availability: Finding original SailMFG-specific hardware (like rudder gudgeons or specific mast fittings) often requires custom fabrication.
