I see you getting more answers so suggest using logic. Pick the perils that you want to be most safe from. Is it typhoons, tsunami, theft, or being rammed by fishing
boats. Zoom in using Google Earth
on each location and pick your location.
Assume zero moorings and be sure your ground tackle is freshly galvanized, sized properly, and estimate how long is long then multiply by three. Likely you should find dive shop operation to dive your boat every 4 months. Anode so?
I am employing about a 200 kilo kellet system to reduce load on chain and anchor
. It is simply two fifty five gallon drums filled with gravel. Here there is a direct hit by typhoon just around 1 per 10 years. Taiwan
has far more typhoons than Palawan.
