I’ve never used the tower clamp mounts, but I’ve had similar struggles trying to secure a GoPro in awkward spots while boating. I once improvised with zip ties on a railing, and it was such a hassle keeping everything steady. Eventually, I got a sturdy clamp-style mount that locked into place, which solved the problem, and now I can just focus on catching good angles without worrying about it falling apart halfway through the trip.
