Patented convertible technology
Patented convertible technology by Van Diemen
The patented convertible technology from Van Diemen has electric windows and opening roof, which gracefully take any position at the touch of a button.
This technology converts a vessel from an inflexible form to a dynamic boating experience.
Versatility at the touch of a button
Fine tuning the guest experience for optimal comfort is achieved by raising and lowering the roof or windows, which operate independently or together.
Elegant and enclosed with the windows raised, guests are protected from inclement weather. This technology coupled with the best boat builders in the world, ensure that all who step aboard experience uncompromising style.
Convertible bowrider with T-top
The dynamic roof allows it to be raised seamlessly overhead of the guests when desired. The open form can be adjusted to embrace the invigorating ocean air and provide the perfect T-top shade when the vessel is at anchor or underway. In this form it is ideal for sports pursuits and fair-weather cruising.
Enclosed cabin
Transforming in seconds, the Van Diemen patented convertible technology accommodates comfort in any weather with the convertible electric windows rising to meet the descending roof to shelter passengers from the elements.
Compact
When stowed height matters, the Van Diemen convertible delivers. From open to closed in under a minute, the roof and windows are fully lowered and the console retracts which provides security and cover for the interior and low profile garaging.
