Here is a Helix 10 on a RAM mount
I currently run a SOLIX 15 on a TH Marine KONG.
When ever I mount any graph on the bow area I install a metal plate under the fiberglass to add support.
Here is my experience with large graphs on the bow. You want the ability to fold them down when running in any type of rough water. A wave over the bow will rip one right off.
It happened to my Solix 15 on Champlain this year. Luckily it just fell off the mount and on the deck. Was able to unhook it, finish the run, then get to my first spot and secure it with bungees and zip ties so I could still use it the rest of the day.
Im working a video that will cover how to install a Mini Kong and Helix 10 at the bow. It will be on my youtube channel. Should be complete in a week or two at the most.
