you are absolutely right in establishing the conflicts of a 30ft weather hull, especially as compared with the tris on the market. Im unsure how successful Farrier has been in other sizes since the initial 6.8m, but that first boat established the market and position for the now popular and competitive trailerable trimaran.


Tri Competitive
With 30ft weather hull the Internal volume is going to be tight, especially where you wish to obtain standing room. I think the existing configurations havent really optimised a four berth conducive to fast passage making and would offer this. The real working space is in the weather hull where headroom wont be contested. Maximising that length with just single berths on each end gives more length in the hull, but we are still stuck with stooped headroom saloon unless largish sliding hatch is offered, with perhaps a simple pram dodger on the weather edge.

Still within the saloon, there is still enough length on offer to situate pilot berths within the limited headroom space at each end. This neatly expands the working headroom to suffice a generous galley within the hull, stepping up into the open top under the pram with settees fore and aft.


The Cruiser
It gets considerably more difficult to offer standing headroom in a cruiser within a 30ft length. For the mostpart we have been attempting to work 2 doubles, a galley, a micro bathroom and a saloon. The result faces the same impediments as catamaran hulls in these lengths, it becomes boxy, tall, and may impact sensible bridgedeck clearance. I think people like myself have been trying to have too much saloon headspace which wouldnt be asked of a comparative 30ft cat where saloons are basic, and have standing room only as an isleway typically aft of a U shaped settee..

Putting it all back together, doubles each end of the hull, head/shower between, steps up to the saloon between head and cabins. Situate the galley in the transition space between the hull and the bridgedeck just slightly pinching bridgedeck clearance, with facilities somewhat protruding into the bathroom space as required. Its not especially different from Cruiser 60 in that respect, just scaled down.

Settees fore and aft with nav on one end minimises the headroom areas footprint to the area between the settees, declining to that stooped 4'-6" when fully fore and aft. It makes for a very dished cabin roof, but that makes it stronger too.

The displacement of a 30ft is barely capable at 0.75 x 9.1 x .831 x .277 for 3468 lbs. The slightest stretch to 10m 32.8ft gives 0.75 x 10 x 0.9 x 0.3 for 2.025kgs or a more comfortable 4.455lbs, but grows the lee hull to 49ft+ from 45ft.

People are going to find their minimum cruising boat within and around those dimensions, and the actual boat cost (subject to further discussion)  wouldnt be that different between the two which will tend to favour the 50ft. Basically the seakeeping and speed of a 50ft boat on 33ft cat numbers, whats not to like?
