Re: How is your zodiac setup?
I don't have any pics at hand but here are some quick descriptions that might give you some ideas on how to rig your boat. Let me know if you need more details or specific pics.
Seats: Throwable floatation cushion (which doubles as a float for a current line). I sit on the cushion on the floor with my back against one tube and my feet up on the opposite tube -- my boat has tiller steering and this is a very comfortable position for cruising. If I need better visibility, I sit on the tube. The only time I've used a proper seat was when camping at Lake Powell. I bolted a folding bass boat seat to the lid of a sturdy plastic storage box. It was useful for extended cruising and fishing but it took up a lot of space and I don't use it when I'm diving.
Coolers: I only take a hard cooler if I'm camping. When I'm spearfishing and the weather is warm, I take an insulated fish bag with ice.
Anchors: 2kg bruce claw with 15' of chain and 300' of line in a small crate.
I made up a 6' bow line with a heavy stainless clip on each end. One end is clipped to the bow of the boat. When I anchor, I tie an butterfly knot in the anchor line and clip it to the other end of the bow line. This way, I don't have to go up to the bow to untie the anchor line when I want to move the boat.
The bitter end of the anchor line is tied off to a float with my name and contact info on it. If the anchor gets impossibly fouled or if I have to move the boat in an emergency, I can dump everything quickly and come back and retrieve it later. If I'm diving, my backup/emergency anchor is a weight belt tied to the current line. If I'm camping, I take a small folding grapple as a backup/stern anchor.
PFDs: I strap them under the lifeline that goes around the bow. They don't take up space, they are easy to get to and they are hard to forget.
Ropes: I have short dock lines with stainless clips on the end. They double as gear lines when I'm diving.
Gas tanks: My main tank is a 12 gallon tank (I got the taller version rather than the wider one so it uses less deck space). If I need more gas, I carry a 5 gallon can.
Main VHF and fish finder/GPS combo: Mounted on stainless steel brackets on the transom. When I first got the boat, I didn't want to carry a big battery, and tried to run the fish finder off a small 12v AA pack. After a while I got a small PWC battery and I think it's worth the space it takes up. Electric start is nice
Emergency gear: I keep all my CG required gear/emergency gear (aside from the PFDs) in a 5 gallon bucket with a lid -- cheap, tough and waterproof. Items include handheld GPS, flares, satellite beacon, navigation lights, flashlight, towing bridle, bilge pump, small hand inflation pump, fire extinguisher, first aid kit, waterproof coats, drinking water, energy bars etc.
Tool kit: Basic tools and repair supplies in a small dry box.
Handy storage: I put one of these mesh pockets on the transom for keeping stuff like the handheld VHF radio, sunglasses, whistle, sunscreen water bottle etc. The suction cups don't work too well so I modified with a hook.
Deck mat: My boat has an aluminum floor and stuff slides around on it. I got one of these rubber drainage mats and it helps a lot. Also protects the deck from tanks/weights and other abuse:
