This may really be a dumb question, but as I look at the 170 I notice that the 3 forward hatches; one big center fish hold and the two matching side units do NOT have latches to hold them down. Do you folks who run one see the need? My last center con really needed to have the twist lock latches engaged or I would get noticable slamming noises on my holds lids. Just think its odd, so I figured I would ask...........more trivia questions to come.
