I don't think many will recommend the AZ3 tripod - one of the other alt/az tripods like GS alt/az(or bintel equivalent) or vixen porta mount might be worth a look. If looking at ocean yo will probably want an erect image diagonal - so you can look at things right way up and left to right.
Try looking at the bintel.com.au site &
