Captain Rolf – Technical Background & Marine Survey Experience

With a Bachelor’s degree in Marine Technology, I’ve spent my entire career in the boatbuilding and composites industry.
I co-founded Friendship Yachts, where we developed and built the Friendship 28 and Friendship 34.

From there, I worked on a wide range of composite-based projects, focusing on hull design, material layups (epoxy, polyester, carbon), structural integrity, and finish quality.
My work has always been hands-on—supervising builds, setting up production teams, and consulting on technical specs with naval architects and production managers.

Based in Friesland, I’ve been involved in the setup and supervision of yacht builds in the Netherlands and abroad. I’ve worked closely on design-to-production transitions, structural quality checks, and final fit-out phases.

Notable projects and collaborations include:

Polyfalk – composite construction and fit-out

Hoora – production and optimization

Novee – small boat composite builds

Venegy Yachts – prototype ,early production and support

ONY – startup assistance and build supervision

Rapsody Yachts – classic line detailing and build

Dutch-E – electric yacht integration

Koopmans Yachts – aluminum and composite builds

Sapphire Yachts – carbon performance yachts

Wind turbine blade fabrication – advanced composite applications
Carbon fiber light weigt dinghy model Nautix 330 in vacum infusion 

In my  mid 30s, I opened a small boatyard and *company Molding solutions  and continued my involvement in all phases of yacht construction—while also working as a marine surveyor.
I've surveyed a wide range of vessels (GRP, composite, and aluminum) for both private clients and insurance companies, focusing on:

Structural inspections and repairs 

Osmosis checks

Hull thickness tests

Rigging and deck hardware assessments /inspections and adjustments

Pre-purchase and post-incident surveys.


My technical background and decades of hands-on build experience give me a solid foundation to evaluate both new builds and aging vessels with a trained and practical eye.

Now im slowing down but still busy with boats .8 years ago i sold my business and move to my catamaran NOVA /currently in the Caribbean.
Im helping many sailors around giving my knowledge and giving helping hand if needetneeded
