As I write this I can only think of three cases for which a dagger-board in each ama should be considered.

Trimaran ama. The main one is when one is sailing a VERY light trimaran probably of all carbon fiber will high buoyancy amas that will frequently be pushed to sail on one ama. Multi-hulled sailing vessels are a special class of boat. This is because even when it is filled with water the buoyancy of a single outrigger hull or ama can easily keep the entire yacht afloat.

And the cat type 6 beam 23ft. The high buoyancy planing geometry is highly resistant to burying the bow at any speed. Close-hauled with slight heeling and the windward ama side hull in the air even in heavy seas you feel safe and the boat is easily controlled.

The ama offers greater resistance to the boats and unlike monohulls trimarans rarely sink. Semantically the catamaran is a pair of Vaka held together by Aka whereas the trimaran is a central Vaka with Ama on each side attached by Aka. What it means is that this particular vessel is composed of three hulls that aid the boat during sailing but also provide interior spaces for the crew and guests to enjoy.

Not good for steering also the trim pushes the bow of the ama under. In the UK the main hull of a trimaran is called simply the main hull or. Timelapse gluing amas together.

Ama Shapes These hulls are a direct descendant from Aoteas amas which have worked brilliantly. In the beginning she was a bit timid with her tri. Ama to Ama sun awning that zips to the mainsail boom bag.

The trimaran Type 3 high buoyancy amas has an overall beam of 32 ft. Given two boats of the same length the trimaran has a shallower draft a wider beam and is lighter than a typical monohull. It really depends on the type of trimaran were considering.
