What our clients say

Reviews

“Spike is a wealth of knowledge when it comes to high performance multihulls like my Gunboat 48. ”

Over the years, he’s supported me with resources, connections, and advice, it’s been invaluable.

John John Florence

3X World Champion Surfer, Olympian, Founder of Florence Marine X

“As a seller of a higher end performance catamaran, Rapide proved to be the ideal choice for me, for 3 main reasons. Spike brought to bear a really effective combination of in-depth product expertise, sound advice on pricing and position, and solid buyers well matched to the boat.”

High performance, blue water, catamarans are a very niche market. Spike’s years of experience in this field really set him apart from other brokers that don’t specialize in this area. For this reason he provides better feedback on positioning and pricing and most importantly finding qualified buyers that understand and appreciate and are willing to pay for the special capabilities of high performance catamarans.

Rich Schneider

Seller Balance 526 Blue Diamond

“Thank you for offering an alternative to all the shit brokers out there! We feel fortunate to be working with you.”

We came to Rapide looking for a safe, well-performing catamaran that could take our family around the world. As passionate sailors with a clear vision—and after a frustrating experience with another broker—we knew we needed someone transparent, knowledgeable, and truly on our side. Spike listened. He understood what we were after. It’s rare to find a broker who genuinely gets it, and even rarer to find one who truly cares. That’s why we’re so glad we found Rapide. Thank you.

World Cruising Dream

“In the world of performance yachts, no one matches Spike Abrams technical capability, commitment to excellence, and high level of customer service.”

Spike’s Rapide Yacht Group had it all together… from the very first contact he gave me solid advise and handled a complex transaction expertly at every hurdle and step. Engaged and responsive at all times, even after the close, I couldn’t be happier.

Edgar

Buyer Gunboat 60 Moementum

“Trustworthy, hardworking, and most friendly. What started in a search for a Gunboat, ended in a long-lasting friendship and relationship with the guy who sold it to us.”

It has been the longest time since my dad dreamed of owning a Gunboat. With the long dream came the longest road. There has been so much consideration, so much decision making and so many emotions involved in this process. It has truly been overwhelming and yet so fulfilling. With all honesty, if it wasn’t for Spike we would not be here and proud Gunboat owners. Every text message, every phone call, every trip to see a boat, every decision and indecisiveness we had -Spike was there, answering honestly with our best interest at heart.

Buyer - Gunboat 57 Vai Vai

“Spike's hands-on experience running and managing a similar Gunboat has proven invaluable as we embark on our adventures into the Pacific.”

As the proud new owners of a Gunboat, we required a deep level of expertise in managing our program. We engaged Spike early in our ownership to help with project set-up as well as develop ongoing systems and processes that simplify and optimize our ownership experience. Alaia has an ambitious cruising plan. Spike’s hands-on experience running and managing a similar Gunboat has proven invaluable as we embark on our adventures into the Pacific

Nick Thompson

Buyer & Seller Gunboat 60 -

“Spike Abram is one of the rare professionals in the multihull space who combines deep technical knowledge with real diplomacy”

Identifying and hiring a knowledgeable owner’s representative to protect a client’s investment during construction is essential. A strong project manager must balance technical expertise with clear, tactful communication. Spike is one of the few professionals in the performance multihull segment who brings both—and does so with integrity.
