Equipment recomendations

Here is a list of gear recommendations you may find useful.

Spray skirts and replacement neoprene covers
Rasdex NZ manufacturer of Spray decks, cockpit covers, neoprene hatch covers and more.   Good quality, Good prices and fast delivery
Safety gear
WhistleNRS Storm Whistle
The loudest whistle made
KnifeNRS Pilot Knife
NRS Co-Pilot Knife
What particular brand is not such an issue, what is important is corrosion resistant, blunt tip to prevent self injury, ability to attach a lanyard and secure to your PFD.
VHF RadioUniden MHS127
Mine is 5 years old and still going and comes with AA backup option for those long expeditions away from chargers
Paddle FloatInflatable paddle floats would be my recommendation, I have found the buoyancy in some solid foam versions to be insufficient to self rescue.  These can be found online or ebay for around $50-60
Hand pumpSea to Summit 
The sea to summit pumps seem as good as any.   Just maybe avoid the cheap ebay brands.   Manual pumps are a good backup, but ultimately you really want an electric bilge pump for hands free operation.
Waterproof Mobile PhonesAGM M9
Aspera R40
IP68, old school buttons, works with wet hands.
Tow LinesKey criteria here is quick release at at least one end, floating line.   There are many systems though, my preference is a waist tow.
Contact Tow Line
Long Tow Line
Waist Tow Line
The cheap alternative is get 15m of floating line and learn the highwayman's hitch.   Very versatile, adjust the length.
CompassesThe simple solutions would be a Silva Kayak 58 compass, attaches to deck lines with bungee.   For a more permanent solution Silva 85 or Ritchie deck mount are good.   Alternatively a good base plate hand held compass can suffice.   DO NOT buy cheap compasses of ebay, these are essentially toys.   Spend the money on a good brand, like Silva.
