How am I going to afford to build a 62ft CATAMARAN? - (Episode 384)

In the bustling roadstead of Chalong Bay off southern Phuket, former superyacht chief engineer Colin MacRae stood on the deck of his battle-hardened vessel, contemplating a transition that will redefine his maritime career. For eight relentless years, the central saga of Sailing Parlay Revival has followed the salvage, structural rebuild, and worldwide circumnavigation of a hurricane-devastated Lagoon 450. Having resurrected the multihull from a total loss in the British Virgin Islands, MacRae steered her across the South Pacific, around New Zealand, and through Southeast Asia. Now, as the yacht readies to depart Thailand for Malaysia and the Indian Ocean, MacRae has unveiled preliminary blueprints for an even more audacious endeavor: designing and constructing a custom 62-foot expedition catamaran from the ground up.

Stepping away from a proven, debugged voyaging home to commission a blank-slate multihull is a daunting financial and logistical undertaking. While production catamarans dominate global charter fleets, their fixed keels and lightweight interior fitouts often fall short of the structural invulnerability demanded for high-latitude voyaging, deep-ocean exploration, and commercial expeditions. MacRae’s transparent breakdown of build costs, capital sourcing, and shipyard operations offers an unprecedented case study in asset liquidation, equipment syndication, and heavy shipyard project management.

The Capital Blueprint: Deconstructing the Build Budget

When structuring the financial mechanics of this ambitious endeavor, Colin MacRae recognized that transitioning from SV Parlay into world-class Catamaran Construction required an exhaustive audit of modern commercial Boatbuilding. Documented openly on Sailing Parlay Revival, this Custom Catamaran project relies on balancing upfront capital reserves against the unforgiving financial demands of contemporary Marine Architecture.

Multihull fabrication reveals severe industrial cost thresholds. In soliciting competitive quotes from shipyards across South Africa, Australia, and New Zealand, MacRae determined that bare aluminum structural welding alone ranges from $300,000 to over $700,000 USD. This baseline covers solely the hull shell, crossbeams, bridge deck plating, and bulkheads before mechanical systems, engines, wiring, or rig extrusions are placed. With raw 5083/5086 alloy plating and engineering overhead included, the bare shell represents only the initial stage of a multi-million-dollar capital commitment.

To fund the build without institutional private equity, MacRae established a four-pillar capital strategy: strategic commercial hardware partnerships, asset liquidation, structured marine debt, and media monetization. Technical partnerships with premier suppliers—such as Precision Sails for high-performance sail wardrobes, Highfield Tenders for aluminum support craft, and Cromox for stainless steel anchor chains—yield major capital savings. At the METSTRADE marine equipment trade show in Amsterdam, MacRae opened direct negotiations with electronics and deck hardware suppliers. To provide liquid capital, MacRae will liquidate personal savings earned from three seasons as chief engineer on Bravo’s Below Deck, combined with the bittersweet sale of SV Parlay. Because the vessel serves as his permanent primary residence rather than a recreational luxury, MacRae is securing a commercial marine mortgage while dedicating all media revenue from brands like Surfshark VPN directly into build escrow.

Naval Architecture and Performance Engineering

Developing an uncompromising transoceanic voyaging platform forced Colin MacRae to integrate eight years of hard-won lessons aboard SV Parlay directly into the vessel’s foundational Marine Architecture. On Sailing Parlay Revival, every structural calculation for this Custom Catamaran reflects how advanced Catamaran Construction and cutting-edge Boatbuilding can eliminate the vulnerabilities inherent in mass-market multihulls.

The engineering philosophy behind the 62-foot platform tackles the compromises common to production catamarans: bridge deck slamming, excess displacement, and structural flexing under torsional sea loads. Having executed structural repairs on fractured forward bulkheads in Panama and addressed secondary tabbing rot in Thailand, MacRae favors a heavy-duty marine-grade aluminum hull or a vacuum-infused epoxy composite sandwich reinforced with unidirectional carbon fiber on critical load-bearing bulkheads.

Hydrodynamic efficiency is centered on retractable carbon fiber daggerboards rather than fixed low-aspect keels. Fully deployed, these high-aspect foils enable close-winded 30-degree pointing angles while minimizing leeway. In downwind tradewind conditions, retracting the boards dramatically cuts wetted surface area and drag, yielding effortless double-digit speeds while reducing draft under four feet for shallow atolls. For power autonomy, the yacht expands upon the 2,160Ah (26 kWh) lithium bank from SV Parlay into a 48V DC bus architecture charged by dual Integrel engine generators and a massive solar hardtop.

The Coomera and Gold Coast Shipyard Nexus

Identifying the ideal industrial fabrication facility became a paramount milestone for Colin MacRae, as realizing this Custom Catamaran required anchoring Sailing Parlay Revival within an elite center of Marine Architecture. Looking past the maintenance limitations of SV Parlay, committing to heavy Catamaran Construction demanded access to world-class Boatbuilding yards equipped for multi-year industrial refits.

While evaluating bids from Cape Town to Auckland, the Gold Coast City Marina & Shipyard (GCCM) along the Coomera River in Queensland, Australia, emerged as a premier build site. GCCM offers an integrated maritime precinct spanning 175,000 square meters, equipped with travel lifts up to 300 metric tons and more than 90 on-site trades, encompassing master aluminum fabricators, composite laminators, and certified marine electricians.

The geography of the Gold Coast corridor provides unmatched staging advantages. Protected deep-water access along the Coomera River leads past the Southport Yacht Club into the Broadwater fairway, offering sheltered waters for pier-side systems commissioning. Once mechanical and electrical trials conclude, the Gold Coast Seaway provides immediate access into the open Pacific for rigorous ocean trials. Building within the Australian framework ensures construction adheres directly to Australian Maritime Safety Authority (AMSA) domestic commercial vessel survey standards and CE Ocean Category A certification, enabling high-end expedition charters and passenger voyages.

Deck Chores and Transit Prep from Chalong to Langkawi

Even as vision documents and structural plans for future Boatbuilding progress, Colin MacRae remains bound to the relentless maintenance schedule required to keep SV Parlay seaworthy. On Sailing Parlay Revival, the crew recognizes that master-level Catamaran Construction and long-term Marine Architecture aspirations mean nothing if the existing Custom Catamaran systems fail on passage.

In Chalong Bay, Phuket, the crew focused on vital maintenance before embarking on the 140-nautical-mile passage south to Langkawi, Malaysia. Fueling was the first priority; having recently cut open and rebuilt aluminum fuel tanks damaged by diesel bug, MacRae bunkered 650 liters of diesel at 45 Thai Baht per liter (~$1.60 USD/L), filling both 500-liter wing tanks to their 1,000-liter (264-gallon) capacity to prevent condensation in the tropical heat.

Simultaneously, the crew tackled an unglamorous head overhaul. Crew member Steve, a former Florida construction company owner, dismantled the starboard toilet to clear heavy calcium carbonate encrustations—a reaction between uric acid and saltwater minerals that had choked the discharge line. The team cleared the deposits and installed heavy-duty sanitation hoses from local Phuket chandleries. Steve also fabricated companionway shelving from salvaged marine laminated countertop, while Benji cleaned and rebuilt the tender’s carburetor seals and jets ruined by degraded shore fuel. After shedding 500 pounds of spare pumps and cables with local charter operator Marcus, the crew welcomed Delaware broker and Platinum Patron Michael Davis aboard for the six-day passage into Malaysian waters.
