When we have traveled from WL to Contemporary or FW it has always been on one of the larger boats, which is capable of taking an
ECV. My understanding is that on that route [WL, CT, FW] there are two boats at a time which make the loop and at least one at any time will be the larger style boat, if not both of them.
OTOH, for example, the boat that goes between MK and GF and Poly is almost always the small boat style that cannot handle an ECV.
Gap2368: The boat captains have radios and can call in for a larger boat to make a stop if needed.
