Don't know about the fish on arches.Seems like they are kind of industrial looking.How many rod holders do you need,and are you mounting a radar on it?
You'll have to pay extra for the mounting plate and any additional rod holders.It's also nice to have some flat mounting plates on the Sides as well to hold other equipment.
I had a custom arch made by Atlantic towers for my 23 Tsunami.It set me back 1,800 bucks but I had extra rod holders installed on it,and that included delivery.They also make a fit all type arch for less money.
I searched a long time for an affordable tower and found that it wasn't uncommon to see prices of more than three grand.Most were from custom fabricators who do awesome work and also the install.
It was to rich for my blood,so I ended up at Atlantic.I'm very happy with it.
