I pulled my copy of Jentschura and it does reference that the converted Momi class "patrol boats' did carry just one daihatsu, but other sources I have seen, including the Combined Fleet web page, claim that two could be carried and launched. It's a small matter, as I concur with your other remarks regarding the limitations of these fast troop transports. Certainly they were NOT capable of fulfilling Dabrob's claims of being able to carry ten daihatsus and and around 700 troops. I also agree that their engines would be worn out and probably not capable of anything like a sustained 18 knots. Instead of landing 4,200 troops, Dabrob's patrol boats would land, at best, around 240 troops armed with nothing more than their rifles and MG's and the ammo they could carry in their pockets. Instead of being a serious threat, the US defenders would hardly break a sweat eliminating these hapless invaders. But then, that is typical of his "research".
