Danny how old is your boat ? the reason I ask is I think you have the older XR24 hull; which personally I think was the nicer looking boat rather than the Lynx. Notice the full bow rather than the later concave bow of the lynx.
You might be interested to read the fourth paragraph down.
Although when I spoke to him recently about the Lynx he did say he didn't design the XR series. They first appeared in 92 with the 18 and 20, followed by the XR24. They were always a fast boat designed on a "delta Conic" shape. XR24s were built by Damen Bloor and Peter Kidd down in Falmouth. XR18 and 20s by Osprey in Standish, before they sold off the business. Worth doing a search on here for XR24 as we have discussed it before.
The hard nose has a number of advantages, storage space, good way of securing the tubes to the front of the boat and possibly cheaper to manufactuer the tubes, certainly easier and cheaper to replace one side tube if it were ever seriously damaged rather than the whole lot.
The viper series can be traced back to the Osprey Falcon range and from there to Fletcher in the late 80s.
I would have thought the XR/Lynx with its lighter and narrower hull should have been faster, it certainly has a big flat running surface to make it go.
