Dziś kolejny „plankton” :) Wymyśliłem sobie taki oto kuter mający pełnić funkcje patrolowo-dozorowe. Okręt jest próbą odpowiedzi na znaczne straty, jakie ponoszą w trakcie działań bojowych nasze dozorowce, które wskutek mizernej prędkości, w obliczu okrętów wroga zazwyczaj kończą na dnie. Nowe jednostki wywodzą się w prostej linii od kutrów torpedowych typu CKT-9. Do celu jaki im wyznaczono, okręty dysponują zwiększonym zasięgiem, który wynosi prawie 900 Mm i co jak sądzę jest niezłym wynikiem jak na tak małe jednostki. Oczywiście, wzorem swoich torpedowych protoplastów dysponują one też dużą prędkością, która ma pozwolić na ewakuację po ewentualnym dostrzeżeniu wrogich okrętów i nadaniu odpowiedniego meldunku. Napęd zapewniają podobnie jak w poprzednich typach silniki spalinowe, ale zrezygnowano z dodatkowych silników elektrycznych. Uzbrojenie zaś składa się z 1 działka szybkostrzelnego Hotchkiss kal. 47 mm oraz 1 karabinu maszynowego. Działko to model z 1884 r. a więc staroć, ale mamy sporo jego egzemplarzy w magazynach i grzechem było by ich jakoś nie wykorzystać.
Jednostki, jak w sumie eksperymentalne, powstały w ledwie 3-okrętowej serii. Od tego czy i jak się sprawdzą, uzależniona jest ewentualna kontynuacja ich budowy lub skonstruowanie następców.

Kolejne pomocnicze patrolowce...
Dziś wiele nie napiszę, bo i niespecjalnie jest o czym. Prezentowanymi jednostkami są kolejne pomocnicze patrolowce. Tym razem są to dwie jednostki powstałe z nieukończonych wskutek wojny małych statków pasażersko-towarowych. Okręty mają po niespełna 900 ton wyporności oraz przyzwoitą prędkość 15 w. Uzbrojony są w pojedyncze działo kal. 75 mm na dziobie i dwa 57 mm Hotchkissy na podstawach umożliwiających ogień przeciwlotniczy. Jest to taki eksperyment, czy udany, to się okaże. Oprócz tego w roli wczesnej broni przeciwlotniczej zamierzam wykorzystywać różne inne dostępne modele broni, jak Maximy, działka McCleana, karabiny maszynowe, Hotchkissy kal. 37 i 47 mm i co tam się jeszcze znajdzie w magazynach;)
Oprócz tego, okręty te mogą zabrać na pokład ładunek 40 min, które są stawiane przez drzwi w rufowej części kadłuba.

"Ciężkie" kutry torpedowe
Miały być „bieda-kutry”, a wyszło coś całkiem przyzwoitego. Nazwałem sobie to cudo „ciężkim kutrem torpedowym” (w skrócie: CKT), bo jest dwa razy większe od dotychczasowych jednostek, i ma na uzbrojeniu 2 torpedy. Do tego dochodzi działko MacLeana (czy McCleana – bo zapomniałem jak się ten konstruktor nazywał) kal. 37 mm. Oczywiście, tak uzbrojone okręty nie są nadzwyczajnie szybkie, ale też nie powolne – osiągają bowiem ponad 32 w. (oczywiście w ślizgu – jest to prędkość po korekcie o współczynnik 1,75 w stosunku do wyliczonej przez program). Napęd zapewniają silniki spalinowe, oraz dodatkowy silnik elektryczny, który może być użyty samodzielnie, do skrytego, cichego podejścia do celu na małej prędkości (np. w nocy). Okręty posiadają 3 śruby, z czego jedna jest napędzana silnikiem elektrycznym. Przewiduję dla tych jednostek pewną wielozadaniowość – jeśli by się nie sprawdziły jako ofensywne jednostki torpedowe, można by je używać np. jako kutry trałowe, małe ścigacze okrętów podwodnych )(po zamianie torped na bomby głębinowe) czy kutry dozorowe.
