The boat had two bench seats in the cabin forward of the bridge and two in the one aft that could be used as berths. We added three hanging pipe racks with bed springs and cot mattresses forward and converted the seat backs in the after cabin into berths that were hinged to serve as both berths and seat backs. This gave us a total of nine berths. We carried cots on board for two to sleep on the bridge and four in the after cockpit, giving us accommodations for a total of fifteen.
As I researched Castro's revolution to write Rebels on the Mountain, I learned that he had attempted to purchase a P-250 Crash Boat like ours to transport his group of 83 rebels from Mexico to Cuba. I can't imagine where he would have put them. Indeed, the cabin cruiser he used, the Granma, was only about twenty feet longer.
We frequently observed the impact of artillery rounds on Pooles Island from a safe distance. However, there were times when a few rounds fell short of the island and sank a buoy marking the channel between the island and the mainland. The Coast Guard who had to maintain and replace these buoys were none to happy. They accused the Army of sinking them intentionally. If true, it represented an amazing feat of marksmanship.
As I learned later in my training as an infantry officer, artillery and mortars are principally used in batteries of three to four tubes. One tube fires a round for registration. A forward observer reports adjustments to a fire control team who calculate changes in the weapon's elevation and direction to hit closer to the target. In the case of mortars, they also have to calculate changes in the number of supplemental propellant packages attached to the fins of the mortar round to alter the weapon's range. Several rounds may be needed to bracket the target. When the observer believes that the registration round has impacted close enough to the target, he requests that the entire battery fires for effect. With three or four tubes firing simultaneously, chances are good that the target will be struck. If the target is a group of personnel, the combined bursting radius of all three or four rounds should spread a sufficient amount of shrapnel in their ranks to decimate them.
However, when we observed a buoy being sunk, the canon cockers at Aberdeen usually required no more than two rounds for registration and hit it squarely with the third round. Only later, when I studied artillery tactics, did I come to appreciate their accuracy. The buoys were no more than four feet in diameter!
