So I guess the question is, "What's the best use of a $700 safety budget for a coastal cruising boat?."
2. Chartplotter and AIS VHF
3. Assortment of jack lines, tethers and good PFDs
Number 3 is the answer, plus the following:
a. Inspect and replace as necessary all hoses below the waterline;
b. Inspect and repair electrical system to avoid accidental fire;
c. Inspect and replace as necessary all running lights;
d. Test and repair as necessary manual and automatic bilge pumps;
e. Buy paper charts for your area and proper navigation/piloting tools - learn how to navigate without electronics;
f. Buy handheld VHF and handheld GPS;
g. Buy storm jib and possibly trisail;
h. Buy and install any materiel to ensure your reefing equipment works properly;
i. Tow inflatable dinghy; and
j. Equip and ready ditch bag.
There, I just saved you thousands of $$$ in unnecessary electronics and toys. AIS, chartplotters and EPIRB are not necessary for coastal cruising on a 25' boat, although, of the three, the EPIRB would be the first I would spend money on.
