PRODUCT INFORMATION: HS-250 SPORT

The statistics presented for the various Hyper-SubTM models are estimates based primarily on engineering calculations and do not reflect empirical test data at this time. The Hyper-Sub proof-of-concept prototype is complete and is currently undergoing testing and refinement, and follow-on testing of a production model prototype will be necessary to determine real-world performance. Marion Hyper-Sub does not warrant the calculated performance estimates.


The sleek profile of the Hyper-Sub prototype's bow turns heads at any marina. 

The Marion Hyper-Sub HS-250 Sport is designed with individual owners and charter operators in mind for recreational and tourism use. The HS-250 Sport delivers robust surface and submerged performance with 180-degrees of view through its all-acrylic canopy.

The HS-250 Sport is built to the following minimum specifications.* Each Hyper-Sub is completely customizable to the customer’s needs, and both surface and submerged performance can easily be significantly enhanced and additional capabilities may be added with optional components.
