Tony, it´s great that you are working at this monster of a scenario again. In the next version of SOE the restriction of torpedoing land units and improvements is solved in the following way: Subs with a lethal sea bombard flag and a bombard range of 1 for their torpedoes have the wheeled flag. Coastal water terrain is forbidden for wheeled units. These subs can pass from their harbors over the forbidden coastal terrain by deepwater harbor settings, done with the Quintillus editor. With these settings, that seem to work well on fixed maps (as it is for SOE and 1989), "land-torpedoing" by subs is nearly completely excluded (the exception is, when the sub is on a deepwater harbor terrain). But it comes even better. Paths with land-/sea-intersections of the flintlock patch are replacing the convoy routes from the US and Canada (and to Russia). All kind of land units produced in US and Canadian cities with the names "Convoys from the US or Canada" have different graphics of merchant ships. The land- /sea intersection tiles are not allowed for units with the wheeled flag. The land units with ship graphics are passing along these routes to England and North Africa (and Russia). When arriving in their destinations (per example at present it is working for Glasgow yet, the changes for Liverpool and North Africa still must be set), these units with low level A and D values are upgraded to their normal graphics and values and now per example the transported Sherman tank is looking like a Sherman and no longer like a freighter, but it now has the wheeled flag and cannot move back to its origin, but must stand in Britain and fight (in the later stages of SOE, when all land units don´t have the wheeled flag any longer, the tanks will have to move with their original graphics and values along the land- /sea intersections). The convoy routes now are flanked by deepwater harbor tiles, allowing subs to lethaly torpedo these land units, that are looking like merchant ships while moving on the land- sea intersections and additionally allow ships to cross this land terrain for escorting and attacking duties on the transport"ships". Additionally Flintlock has the limitation for sea units that cannot bombard land units and -terrain on his list.
