Charter Proposal

ContentsWhat this proposal covers.
Dear X,

EYOS is pleased to present our Expedition Partner Proposal for Enigma XK. EYOS would be honored to represent the yacht as both the Central Agency and Expedition Management partner, leveraging our unparalleled expertise and close connection to the vessel.

This is not a conventional proposal. We believe Enigma XK is best served by a hybrid relationship—combining the generalized Central Agency function with the highly specialized Expedition Management one. And there is simply no other company in the yacht industry equipped to provide it.

EYOS pioneered expedition yachting, defining the category in 2008, and remains the world leader in private superyacht expeditions. Our leadership team has been in the expedition cruising industry since its inception—with 350 years of collective experience and a network of travel and marine specialists spanning seven continents. Our team's nautical expertise ranges from sailing yachts and motor vessels to cruise ships, research vessels, icebreakers, and superyachts.

In addition, we provided both Central Agency and Expedition Management to Enigma XK when we originally brought her to market as a polar expedition ship.

As a result, our unique expertise is invaluable to:

Experience matters is our core belief. And relationship matters is the core of our business practice.

For that reason, our proposal foregrounds the benefits to Enigma XK to forge an Expedition Partner relationship with EYOS for both sales and marketing effectiveness and expedition expertise.

We welcome the opportunity to further discuss EYOS × Enigma XK, and we look forward to reaching an agreement. Our team is ready to begin immediately.

Yours sincerely,
Ben Lyons handwritten signature

Introduction

Expedition Partner Rationale.

EYOS is ideally positioned to act as both the Central Agency and Expedition Management partner for Enigma XK.

Unlike other traditional central agents in the yachting industry, we live and breathe the expedition business and expedition geographies. Top industry brokers look to EYOS. If we're endorsing a vessel, they know they can trust in our management.

The fact is, we operate approximately 95% of all Antarctic yacht expeditions and about 90% of all Arctic yacht expeditions. Last year alone, in Antarctica alone, EYOS staff were on 11+ vessels, making us by far the single biggest operator by number of vessels in the entire Antarctic tourism industry.

In terms of operational capabilities, we are simply without peers.

Our dedicated team manages highly complex operations with innovation, knowledge, and experience, making us a dependable partner for captains and owners—from yacht rebuilds and marine consultation to voyage planning and permits. EYOS is the only dedicated superyacht expedition company to be full members of AECO and IAATO and operate with our own permits—we're not reliant on a third party to deliver this important asset. Choosing EYOS as your Expedition Partner streamlines selling to brokers, providing timely, accurate information and deployments.

And with our extensive network of private aviation operators and knowledge of challenging polar weather conditions, we are uniquely positioned to take advantage of one of Enigma XK's core attributes—the heli deck—to deliver exceptional experiences in remote and remarkable locations.

As Enigma XK's single point of contact we would ensure the entire process from initiating sales to delivering superb experiences is cohesive and consistent.

Now, let us introduce you to the EYOS Leadership Team.

Enigma XK in the Industry

EYOS and Enigma XK have history.

When the vessel was market launched, EYOS was the yacht's exclusive Central Agency and Expedition Management partner.

During the time EYOS marketed the vessel, we garnered continuous broker-based charter business. We also generated lucrative charters from non-traditional sources, ranging from major motion picture production and research companies to support for superyachts.

Unlike conventional yacht brokers, EYOS has connections that extend far beyond wealthy families. As a trusted expedition operator EYOS gets many requests—from private yachts for support vessels, from science missions, for regular charter use and UHNWI clients both in the Arctic and Antarctic—which don't go to the commercial market. This is key to EYOS' ability to maximize Enigma XK's revenue.

And the broker community knows that EYOS is highly selective, focusing on unique best-in-class yachts in their various categories.

Since Enigma XK is firmly associated with EYOS, returning her to our management as Expedition Partner will send a strong signal to the industry to expect best-in-class expedition planning, operations, logistics and staffing.

Enigma XK in the Industry

Positioning.

Based on our experience with Enigma XK, her polar heritage and her capabilities, we envision her amid a competitive set that includes Hanse Explorer, SuRi, Arctic and Argus—with distinct advantages. Each yacht shown is a comparable expedition yacht based on overall size, polar experience, and in the case of SuRi, with a competitive feature: a heli-pad.

Positioning

Enigma XK can go where other yachts can't.

She has a potent combination of a strong ice class and a large commercially certified heli deck. EYOS would seek to position her as a unique platform—leveraging these advantages to open new destinations and create new opportunities, like early spring heli-skiing in Greenland.

Opportunities.

As we've said, experience matters is our core belief and relationship matters is core to our business practice.

Our success and that of our clients has been intricately linked to exceptional partners who share our passion for innovation, excellence and the natural world.

Here are only a few examples that indicate how EYOS' network of partners can add value and further differentiate Enigma XK's offerings in the market.

IAATO & AECO

Unlike other superyacht companies with membership in these organizations, EYOS has been a full operating member for over a decade, occupying advisory board positions over the years, as well.

Yachts for Science (YFS)

An innovative EYOS-founded program that recognizes the majority of ocean scientists struggle to get vessel time at sea, and that yachts can be effective science platforms. By matching top-tier ocean science projects with yacht owners willing to provide a temporary research platform, YFS enables owners to host small teams and support vital ocean research. And Enigma XK's clients could enjoy exclusive and engaging access experiences.

EYOS Marketing
Enigma XK.

Marketing is a core EYOS competency. While the tools we use—a website, social media, advertising, editorial and PR—are also used by our competitors, our industry reputation is our superpower.

As we've explained, top industry brokers look to EYOS. If we're endorsing a vessel, they know they can trust our yacht selection, our management, and our ability to deliver an exceptional experience for their clients. Simply stated, most inquiries, whether through brokers, direct clients or travel agents, come to EYOS.

It's why we currently operate approximately 95% of all Antarctic yacht expeditions and about 90% of all Arctic yacht expeditions. And why Enigma XK can rely on EYOS for consistent charter sales.

However, we offer Enigma XK even more—our proprietary in-house Media Studio, a team of professional photographers and videographers who work exclusively for EYOS, documenting our Expedition Partners' yachts and expeditions. We have created an unrivaled library of superb images and dynamic videos that are never generic or cliché—expertly wielded by our marketing team to capture prospect attention and drive interest.

Our team and our credentials have made EYOS the go-to source in expedition yachting—a powerful resource we offer as Enigma XK's Expedition Partner.

EYOS Marketing

Website.

The EYOS website was refitted in 2023 with a focus on large-scale, high quality still and motion imagery and expanded content.

Underpinned by newly implemented, best-in-class SEM & SEO initiatives, our marketing is dynamic, and prospect-focused, not merely a passive listing site.

In addition to the Enigma XK webpage, the yacht will be supported by blog posts, prominently featured in the EYOS video library, in destination-centric videos and in social media Reels.

Advertising.

Our advertising ranges from ads promoting image/brand and destinations to ads for specific yachts. Because we are selective and work with a limited number of best-in-class yachts, we can focus our advertising dollars to drive interest for our clients. The following are some recent examples of ads run in BOAT Magazine, where EYOS maintains a regular advertising and editorial presence.

Depending on the contract, we can create standout advertising for Enigma XK given our Media Studio's outstanding archive of proprietary images.

Public Relations.

EYOS engaged a new PR agency in 2025 that has enhanced our ability to attract attention—for our company and our clients. Since our partnership began in mid-2025, EYOS has received the Condé Nast Traveler Bright Ideas award for our work with Camp Dominica. We've planned two press familiarization trips on two yachts for winter 2025–26 and are preparing for next year's annual Explorer Yacht Summit, exclusively sponsored by EYOS. Spanning the world of both the yachting industry and luxury travel, the EYOS team appears at a variety of events each year, from PURE and Do Not Disturb in the luxury trade, to Monaco Yacht Show and the Antigua Charter Show on the yachting side.

We have received over 98 press placements this year, with features in Forbes and Robb Report, among others, generating high-impact media attention. More importantly for Enigma XK, we're not just seen by the world's press as a yachting company. We're seen as a luxury travel company—greatly increasing our market reach.

Projected Revenue

A deployment schedule built to maximize revenue.

We are confident in our ability to create a deployment schedule that will maximize revenue. For example, EYOS has successfully operated several 'single cabin' scheduled departures, a strategy we could employ to extend Enigma XK's operational windows and increase revenue opportunities.

Anticipated revenue is based on Enigma XK chartering for 12 weeks in Antarctica every year and 15 weeks in the Arctic at 290K EUR per week plus expenses. Alternative, Arctic only deployments may also be considered.

Peter Butz
Chief Operating Officer

Peter Butz has a rare past in expedition travel beginning with an improbable first job in the industry. In his early twenties, planning to quit a dull reservations job in New York City, he was tapped by Lars-Eric Lindblad, considered the pioneer of expedition travel, to head to Antarctica immediately and begin the (seminal) job of driving Zodiacs.

Peter's bona fides in expedition travel are unassailable. He has been everywhere in the adventurous world, including Antarctica, the Great Barrier Reef, the Arctic and the Amazon. Through extensive hands-on experience, Peter has developed a deep understanding of the complexities of expedition cruising. He has progressed from his beginnings in the field through positions of increasing managerial responsibility, culminating in COO positions, including at Lindblad Expeditions–National Geographic where he managed a fleet of six expedition ships that carried thousands of clients annually to far-flung destinations worldwide.

Since joining EYOS, he considers the best part of the experience, for clients and their guests, to be "the part they never see." His penchant is for the planning, the tailoring of every expedition EYOS operates specifically for the participants of that particular trip—their individual interests, their abilities, and their preferences. He believes there is no cookie-cutter approach to any aspect of EYOS Expedition Management. He's participated in developing hundreds of expeditions—to Antarctica, the Arctic, Melanesia, and other remote corners of the globe—and takes professional pride in the behind-the-scenes preparation that makes our clients' charters exceptional.
