I keep extra bedding, (for guests) in some of the compartments under the v berth. And extra towels. These are completely dry and I have never had a problem. Also have the porta pottie, loo paper etc and extra chain for the anchor in other sections. I have a section near the bow which is open to the V berth and there I store extra wet weather gear, extra sets of warm clothing and towels.
Sonia from "Curly Tops" over Christmas completely rearranged my entire storage throughout "Sea Lady" so now I do have difficulty remembering where things are. But at least the same things are now in the same spaces. Handy when checking how much red wine is left
Also have netting hanging thingies that hang from the grab rails. Again - Thank you Sonia. (What a wonderful present.) Which are great for storing fruit, fresh vegies, bread, eggs etc
All the stuff that needs to be removed each trip.
Learned how important that is when I left a small bag containing left over fruit on board for 2 weeks. Bag and contents now in fruit heaven.
Under seats on the starboard side I have more bedding, clothing, TV and in another - booze.
Behind and under seats on port side. Non perishable food, bags, books, tools, BBQ, torches, batteries, cooking utensils.
In the 5th berth under the cockpit. The one you would only put people you don't like has a cockpit table, Shade awning, boat hook, 2 life jackets, autopilot, fishing rod, recharge site for phone etc and also stores the storm boards when underway. Also safety grab bag, containing flares, first aid kit, V sheet, waterproof torch, chemical lights etc
The hatch under the seat in the cockpit, has fuel and other chemicals and bailing bucket. (I have an outboard)
Under the ladder (companion way) is wet weather gear, extra life jackets, wet shoes, battery and extra lines.
Charts in the chart table.
There is an open shelf with racks above the port side seat. For depth sounder, radio, both fixed and hand held as well as cd/radio crockery, cutlery, T towels.
I have one of those Wilshire stay sharp knives in a sharpening holder glued to the bench in the galley. Also easy for grabbing if needed in the cockpit.
Esky and drinking / cooking water in a big 10 litre plastic container live under the chart table.
As I only use the ice chest when going out for a few days. (Again easy to forget what is in there.)
For day and overnight trips, I freeze water in 2 litre containers which doubles as ice and also provides fresh cool water for drinking. Always bring at least 2 x 2L frozen water on board. Use the tank water only for washing as it tastes yuk.
I have more than enough bedding and everything else for 4 people. Have 6 adult life jackets and 3 child jackets.
Cockpit cushions and fenders, which double as extra cushions live on the floor in the cabin when not in use.
Detergent, metho, citronella etc live under the sink.
All works well.
I generally sail solo and the extra gear, bedding etc is really only used occasionally when guests stay overnight on board.
I don't keep extra sails on board. They live in the shed at home.
