Will they work; yes. Is it the best option; no. Do we always do things on our boats that is the best option; no
.
I considered these on my old boat, but decided to go with more rod holders across the transom instead. I've seen lots of fishermen get excited when a fish strikes. This leads to quickly grabbing the rod and POSSIBLY pulling the whole trident out of the gunnel holder and creating quite a mess. Hopefully, your trident is anchored with a bungee of some kind so you don't watch it fall to the bottom of the bay.
So; if you use them, just be carefull and know the risks.
