Are you going to use pneumatic actuated vent valves like Alec has on Shackleton or are you going to try and manifold the vent piping and have single MBT vent valves on the port and starboard side?</div><div><br></div><div>Back to Hank's question, are you going to have a VBT or are you going to handle variable ballast like I do by adding ballast weights at the CG of the boat?</div><div><br></div><div>What are you going to make the MBT segments out of, plastic like <span><span style="color: rgb(34, 34, 34); font-family: Roboto, arial, sans-serif; font-size: 16px;">polyethylene, polypropylene or layup </span></span>FRP?</div><div><br></div><div>Cliff</div><div><br></div><div><br></div><div><br></div>
