The R58 Custom Classic Coke - Built for a Yachting Fisherman by Bob Roscioli

Bob Roscioli enjoys customers who know what they want, because Roscioli Donzi Yachts delivers all that and more-luxury and lifestyle perfected. "We don't copy, we create," he states. Not only does Roscioli fish with his customers to better learn their needs, patterns and style, he walks them through the process of building their yacht-literally.

Roscioli Donzi yachts creates a life size template of the boat, a plywood layout that provides the client with an experiential, walking tour of how the actual boat will "feel." Tweaks and changes can then be made before the boat is built saving time and money and creating efficiencies and comfort levels. The design and construction of the custom R58 "Classic Coke," now offered for re-sale, is an example of what made one client a happy, and a repeat customer.

Just ask the owner:

With at least 10 boats under his belt between the Great Lakes and Florida-most of them custom built, Bud Koch is savvy and meticulous about boating and has a keen eye for detail. While banking was his profession, he is also an engineer so nuances of how to make things work better come easily to him-if not always to the boat builder. But Bob Roscioli understands that eye for detail and made this R58 Classic Coke to his exact specs, creating, fine-tuning and satisfying his wish list. Which is why clients often become friends and fishing buddies, because they know that Bob Roscioli truly cares about their passion, their life and their boats. And that is why Koch-and others--come back to Roscioli to build the next dreamboat.

The R-58 was the first Roscioli Donzi Express and is totally custom, adapted from a convertible mold. Koch spoke with Roscioli while looking for a new sportfish and was assured that his sport cruiser, an upgrade from his prior 45', could be achieved. Koch and his son were convinced after a sea trial in an R-58 in rough seas and bad weather. They were also impressed by the Roscioli Yacht Center and realized the convenience of service, storage and the efficiency of working with the manufacturer instead of a dealer network. The Roscioli Donzi Classic Coke began to take shape.

The owner insisted on bigger power with Caterpillar C32A engines. While he now admits it was a little "overkill," he likes to get to Ocean Reef or the Bahamas quickly for fishing trips and says the boat cruises at 40 knots with ease.

That big power plant caused some alterations in the engine room but Roscioli made adjustments, used space-saving components, and installed the Seakeeper 16 under the cockpit floor where it can be easily accessed when needed. Also, the additional engine weight necessitated a transom extension for a bit more buoyancy, hence the "swim platform" which really became extra workable space to wire in a fish.

The Pressurized Live Well was a priority for the owner, having lost a great deal of expensive live bait to excess pounding in traditional live wells. Roscioli followed Koch's lead and cleverly concealed a double Plexiglas lid under the teak transom to prevent splashing. Now the pressurized live well is part of the Roscioli "Gold Standard" for sportfish boats.

The aft deck starboard helm station was another Roscioli addition as the owner wanted to be able to steer from the cockpit and the Procurve windows and windshield provide excellent visibility not available in most sportfish boats.

Boat and bow control is important to Koch, so Roscioli added a Zipwake trim system-an innovative technological advance through a collaboration of the automotive and marine industries. Easy trim adjustments are now done at the flip of a switch.

Koch credits Roscioli for designing exceptional galleys and heads, creating open spaces with natural light and top quality finishes. He also notes that the company uses many higher end pieces of equipment, like hinges and hatch shafts more commonly found on superyachts. He notes that in each build, "You learn things along the way-and it's kind of fun!"

"Bob and his team are great to work with," says Koch, "His service is second-to-none."

Highlights include:

The VonWidmann Underwater Exhaust System

Now used primarily for military installations, VonWidmann pioneered exhaust technologies in the 1980s. Bob Roscioli discovered the VonWidmann system and has been perfecting its installation in his yachts for 17 years.

While the modular drop-in system has advantages for the builder, it adds considerable value for the owner and captain, by maximizing fuel load and range. Being able to make Nassau, The Virgin Islands or Dominican Republic for the best fishing without fuel worries helps captains and eager fishermen get to their destination with efficiency. And while located in the bilge, otherwise unusable space, the exhaust system makes room for added equipment like Seakeepers.

The system also minimizes backpressure, a drain on engine power, by cooling the exhaust rapidly, using less raw water, which also lowers the temperature of the exhaust water, providing ecological benefits.

Because of its straight shaft, strategic placement and bond to the chines and stringers, the system adds to hull strength, stability and engine room efficiencies.

The Seatorque Bolt on Shaft System (BOSS)

This Seatorque oil bath system likewise became a Roscioli choice to ensure that shaft-line noise and vibration are eliminated at the source. The non-rotating, full-length shaft casing and thrust bearing assembly minimizes mechanical losses, leaving valuable extra power for propulsion. Using rubber mounting with a flexible connection to the propulsion, delivers unrivaled ruggedness coupled with low underbody drag.

Procurve Glass, Installed by Advanced Marine Glass

Procurve Glass Technology creates a chemically strengthened glass product, offering the industry's largest and most technologically advanced wrap-around windshields and windows. This R58 was among the first yachts of its size to feature this design trend toward larger and lighter weight windshields that provide not only more visibility and light, but also more tensile and flexural strength-especially important for wave force and impact resistance. This glass also provides UV protection to reduce fading and aging of interior materials.

While the quality of the glass is notable, the AMG factory installed system and "tip-out" process ensures durability, using the proper and waterproof sealant.

Other Design Features:

Headroom was important, as was the flow of the boat for fishing ease and entertainment, so the 17' 8" beam gave breadth to raise the ceiling heights in both the salon in the three staterooms and en suite heads and below. Matched grain teak custom cabinetry throughout flows with smooth gentle curves and houses an entertainment system and large retractable TV in the salon; in the staterooms, more teak wraps queen size beds, copious storage and TV/entertainment systems. Heads are spacious with luxurious fixtures, glass showers and flat floor drains.

Extra space for rod storage was "uncovered" during the walkthrough as a spacious starboard counter at the helm was found to be perfect length and width to become a sturdy flip-top cabinet to store a collection of premier 20-50 lbs. fully rigged rods. The combination of Stidd leather seats with Air Ride suspension, mounted on teak pedestals, provides ultimate comfort and extra storage at the two-seated helm and at the third navigation station to port.

The wrap-around Procurve windshield offers excellent visibility and natural light throughout the salon where guests can lounge in air-conditioned comfort. A built-in sink, refrigerator, icemaker and wine cooler in the salon add to the ease of entertaining. Opening the broad custom retractable aft window adds more fresh air and connects those in the salon with exciting cockpit action when a big fish is on the line.

Light from the panoramic window extends down to the galley where a C-configuration of teak cabinetry, granite counters and a stylized backsplash provide an ideally visual and practical layout. Top of the line appliances, a customized sink and all the accouterments for food preparation give the chef an ultra-equipped spacious galley.

Venture out to the roomy lanai where colorfully upholstered teak mezzanine bench seats look aft over the teak deck and action at the rocket launcher and Release Battle Saddle. (Roscioli Donzi also adds reinforcement to the floor for each fighting chair's strength and stability.) A second custom starboard helm station aft offers visibility and flexibility to the captain under the ample portside overhang; recessed LED lighting above, adds extra nighttime ambiance.

More rod storage under the gunwale, numerous rod holders, a 56-gallon live well, bait freezers, insulated fish box, Eskimo ice maker and a robust PipeWelders Marine tournament style outrigger system adds to the fishing amenities.

The Roscioli Donzi engine room is always impeccably planned and equipped for maximum efficiency and access to operating equipment. Since the company offers a full warranty on its builds, it takes service of each component seriously, from the Caterpillar C32a engines, that offer cruise speeds of 38-40 knots, with a top speed of 42 knots, to the VonWidman underwater exhaust, Seatorque Control System, Onan 21 KW generator and Seakeeper 16. The painted engine room is easy to clean and bright with plenty of strategically placed lighting.

Technology abounds throughout the boat-a Roscioli priority-ensuring that each client gets the absolute latest and best to enhance the yacht's enjoyment.
