Agree with anchor weights but think you should go with all chain anchor cable on your main anchor of at least 60 metres - you can permanently attach a 20 metre rope rode after this for emergency/cut and run. The extra weight is not much (equal to a small person on the foredeck) and you will not wake up in the middle of the night when it starts blowing worrying that you are about to chafe through your cable (especially when near coral or rocks which slice through rope in no time)! A Fortress anchor can be used as a kedge with very little or no chain to heave off (and easy to handle in the dinghy) or with 10 metres chain and warp for a calm overnight anchorage.
