Over-the-Horizon (OTH-IV) and Long-Range Interceptor (LRI-II) rigid-hull inflatables on stern of USCGC Stone
Above is a screen grab that I thought might be interesting, in that it provides a comparison of the two boats carried by National Security Cutters, the eight meter OTH-IV to the right and the eleven meter LRI-II to the left on the launch ramp.
The LRI-II is only carried on the Bertholf class National Security Cutters. The OTH is carried by various classes of cutters including the 154 foot Webber class (Fast Response Cutters).

What I would have given for either one of those back in 87-89 during my time on the Gallatin. We had the dreaded MSB and 19′ RHI. Radar??? We were lucky if our radios worked back to the ship during line of sight ops. Glad things are much better today.
