My toolkit I carry on my AI contains:
8" Crescent wrench
9/16" box wrench
1/2" box wrench
7/16" box wrench
3/8" box wrench
Short #2 philips head screwdriver
5/16" allen wrench
3/16" allen wrench
1/8" allen wrench
All tools have a (string) loop on them to clip to a Hobie Gear Keeper (#72020001) mounted to my PFD
Also in a baggie:
Spare rudder pins
Spare plastic shear bolts
Spare drain plug
Small piece of 1/2" garden hose (for nose of Mirage Drive
Spare spectra line
odd and end bolts, nuts, washers & cotter pins
All tools and small parts fit in a loc-loc waterproof plastic box in the back of the seat.
I also carry a complete Aka Brace Assembly #79523101 with a cotter pin for quick change out on the water (in the hull).
Also a spare Mirage Drive if going more than a comfortable paddle distance from shore.
Be sure to leash everything in and on the boat (i.e. Mirage Drives).
Safety Items include:
A surfboard leashes on all boats (captains leash!) .
A waterproof Marine radio
Knife mounted on the PFD
100' throw rope bag
You can never be too safe (until the boat sinks from all the extras)
