I've been lurking a while without contributing much, so since I have taken a lot of tips from posts on here and elsewhere, I thought I'd share some pics of my Tarpon, rigged and ready to go. I've made pretty good use of the Slidetrax system and accesories that the Tarpons have, so that I haven't yet drilled a single hole.
Side view (I have since cut down my landing net handle as shown in other pics):
In the rear well I've got my cooler bag, and a small crate that holds my anchor, drift bag, tackle box, burley bucket etc, and has two pieces of pvc which hold my landing net, light/flag pole and also double as extra rod holders.
Here's the cockpit. I use the storage pockets for my knife, pliers, spare lures and whatever. In the centre hatch is a hatch bucket/container which normally holds a container with SPs, lures, leader etc.
Up the front I have a dashboard with two rod holders and fishfinder fitted to the slidetrax rails. Front hatch holds emergency equipment, consisting of flare kit, PFD1 (I wear a PFD2 anyway) and breakdown paddle.
When rigging up/down, the dashboard and fishfinder slide into the rails, and tighten down with an Allen key. Full length anchor trolley hooks onto existing paddle keeper/rear well bungies to include a bit of "give" in the system.
Fishfinder is a single all-in-one setup, with plastic container holding excess cable and battery (powered by 8 x AA batteries). Transducer is mounted to a sidearm that swings over the side when in use.
And that's about it. I like that at the end of my session when I've rigged down, I'm basically back to the bare hull without any additional rigging.
Thanks for the comments folks, this setup is still serving me well for coastal/nearshore expeditions.
