To the Editor, Motor Boating
Dear Sir,
The recent article on power catamarans was excellent and very timely.
However there were a couple of , not really inaccuracies,but more
oversights, that showed up.
The French were not the pioneers in series production sailing catamarans
despite their current dominance. The UK had boats such as the Prout
Snowgoose, the McAlpine-Downey Iroquois, the Catalac and the Heavenly Twins
in volume series production some 20 years before the French juggernaut
started to roll.
The Manta 44 has protected propellers because Cortland Steck uses the "CS"
hull shape we developed in 1983 [See our web site].
Mr Caswell's comments on anchoring may be true for some power catamarans but
they are certainly not true of boats with our "CS" hull form. We often
anchor off one bow. The boats do not hunt when anchored like this. But they
do lie out to one side which can be a bit disconcerting for other boats. The
shape of our hulls means that our designs are not sensitive to cross winds.
A lot of power catamarans do, in fact, have a deeper draught than the
equivalent monohull. Essentially because they have no rocker in the hulls,
and have beaching skegs, our designs go wherever they are pointed
irregardless of the wind direction and strength. Quartering seas are not
really too much of a problem but beam ones certainly
can be.
On a lot of our designs [see; St John, NY51 and 57,IceBear, DeepSea and
Pacific Harmony etc] the cabins are actually up on the bridgedeck and have
walk around berths.
For photographs and images concerning my comments see our web site.
I hope this is of interest to you and I look forward to hearing from you. If
you should require any further information do contact me.
Yours sincerely,
