Broker Overview
As a serious buyer considering a high-performance Convertible, the 1987 Magnum 70, "Triple Crown," represents a unique proposition in the Miami market. This isn't just another used yacht; it's a meticulously rebuilt vessel that marries classic Italian design with modern performance and luxury. Originally designed by Pininfarina, this Magnum 70 Convertible stands out from typical production boats, offering a blend of speed, style, and substantial refit investment.
The market positioning of this Magnum 70 is clear: it targets a discerning buyer who appreciates bespoke craftsmanship and exhilarating performance over a brand-new, mass-produced vessel. Its value proposition lies in the extensive 2012 refit, which effectively created a yacht far newer than its hull year suggests, at a fraction of the replacement cost. The asking price of $899,000 for a yacht with a 2019 survey valuation of $3,000,000, and a replacement value of $6,500,000, indicates a significant opportunity for the right buyer.
The construction quality of Magnum yachts is legendary, known for robust fiberglass hulls capable of handling serious offshore conditions. This particular Magnum 70 Convertible benefits from a complete structural rebuild from the stringers up during its 2012 refit, ensuring the integrity of its foundation. This level of refurbishment is critical for an older performance yacht and speaks volumes about the owner's commitment to its longevity and safety. The deep-V hull design, a hallmark of Magnum, ensures excellent seakeeping and a smooth ride even at higher speeds.
Powering "Triple Crown" are twin CRM 18-Cylinder Diesel Engines, each delivering 1,650 HP, for a combined 3,300 HP. This is a serious power plant, enabling a cruise speed of 30 MPH and an impressive top speed of 48 MPH. Performance like this is rare in a yacht of this size and age. While CRM engines are not as common as some other brands, the fact that the vessel has been professionally maintained for over two decades, with an open-checkbook program, suggests that maintenance has been diligent. Prospective buyers should review the extensive service records and consider a thorough engine survey by a CRM specialist. The 1,200-gallon fuel capacity provides a respectable range for a performance vessel.
The interior layout of this Magnum 70 Convertible has also seen an extensive luxury refit. While specific details aren't provided, the mention of luxury craftsmanship implies high-quality materials and finishes. Magnum interiors are typically well-appointed and functional, and a custom refit would enhance comfort for entertaining or extended cruising. The flybridge, with its custom sport bridge helm and fighter-jet style joystick controls, highlights a significant upgrade focused on modern operational ease and an enhanced driving experience.
Key features and notable upgrades include the complete structural rebuild, the Pininfarina design heritage, the custom sport bridge helm, and the luxury interior refit. The inclusion of a Northern Lights 20KW generator ensures ample power for onboard systems. The availability of multiple surveys and detailed invoices for the rebuild and upgrades offers transparency and confidence to a buyer.
An honest assessment of condition reveals a vessel that, despite its 1987 hull year, has been brought to a very high standard through a comprehensive refit and ongoing professional maintenance. The trade-off for a buyer is the ownership of a unique, high-performance yacht with a significant history of investment, rather than a newer, potentially less distinctive, production boat. The CRM engines, while powerful, will require specialized knowledge for maintenance, which is a factor to consider.
Why should a buyer consider this vessel? For those seeking a fast, stylish, and thoroughly re-engineered Convertible boat, "Triple Crown" in Miami Beach, FL, offers exceptional value. It's a yacht that commands attention, delivers exhilarating performance, and provides the comfort of a luxury cruiser, all backed by a documented history of significant investment and professional care. This 1987 Magnum 70 Convertible is not just a boat; it's a statement.
Why This Boat Stands Out
- Extensive 2012 structural and luxury refit, effectively a newer yacht.
- Pininfarina-designed classic hull with modern performance.
- Twin 1650 HP CRM Diesels delivering 48 MPH top speed.
- Professionally maintained with open-checkbook program for decades.
- Significant value proposition compared to replacement cost.

Notable History
The vessel underwent two extensive rebuilds during its lifetime. The most significant renovation occurred between 2005 and 2012 following hurricane damage, when the yacht was rebuilt down to the hull and structural components. More than $6 million was invested to create the yacht seen today.
Magnum 70 Background
The Magnum 70 series represents one of the most distinctive high-performance yachts produced by Magnum Marine. Early examples of the Magnum 70 were equipped with powerful CRM diesel engines and designed to deliver exceptional speed, handling, and long-range cruising capability.
One of the first Magnum 70 models, delivered in 1989 with twin CRM 1,800 horsepower diesel engines, operated extensively in Japan's Inland Sea. Prior to entering service, the vessel underwent traditional Japanese blessing ceremonies performed by both Shinto and Buddhist priests, a customary practice intended to purify and protect the vessel during its voyages.
The yacht operated successfully in Japan for many years and developed a reputation for reliability and durability. Decades later, the vessel continued to remain in service, demonstrating the strength of the Magnum hull design and engineering.
Today the Magnum 70 series remains highly regarded for its combination of Italian styling, powerful performance, and custom craftsmanship.
Expert Review
The 1987 Magnum 70 Convertible, 'Triple Crown,' represents a compelling option for a specific type of buyer. Magnum's build quality is historically robust, known for their strong fiberglass hulls designed for speed and seakeeping. The extensive 2012 refit, particularly the structural rebuild, is a critical factor here, elevating the vessel far beyond a typical 1987 model. This level of investment suggests a virtually new boat beneath the original hull lines.
Sea-keeping is a hallmark of Magnum yachts; their deep-V hulls are engineered for performance in challenging conditions, offering a stable and dry ride. The 48 MPH top speed is exceptional for a yacht of this size, making it a true performance cruiser. Value-wise, the asking price, relative to the documented refit costs and recent survey valuations, indicates a strong opportunity. You're getting a significantly upgraded vessel for a fraction of its replacement cost.
For survey advice, a pre-purchase inspection is paramount, focusing heavily on the mechanicals, specifically the CRM 18-cylinder engines. While powerful, their specialized nature means you'll need an engine surveyor with experience in these units. Furthermore, a detailed review of all refit invoices and maintenance records is essential to understand the scope and quality of work performed. Don't overlook the electrical systems, given the age of the original wiring combined with modern refits.
Owner Sentiment
