[QUOTE=ldrhawke;174608]Actually we continue to attempt to compare apples to oranges. Your 435, now stretched a couple of feet in hull length to be a 455, is a relatively small boat compared to most Chris White Atlantics. The Atlantic 48 is physically much much bigger boats and over 2' wider and carries 50% more sail area.
Your FastCat 435 is dimensionally is almost identical to an Atlantic 42 in width, water line length, and sail area. Although your 435 surprisingly draws nearly a foot more draft
for being 2 tons lighter.
We can talk numbers all day, and accomplish little, the proof is in actual sailing weight and real life sailing performance, which is what all this keeping it light talk is about anyway. This big old heavy Atlantic 42 shown below is sailing at over 20 knots, not surfing down a wave, and has a stated displacement of 15,500 lbs by the builder
. You state your Fastcat 435 and 455 weigh nearly 2 tons less in the water than an Atlantic 42, so 435' and 455's should be performance screamers.
Do you have any photos like this or comments from Fastcat owners as quoted below? If FastCats are as light as you state when under sail they should perform even better. You have stated in a "Cruising World" write up that the max speed of your 435 is only 14 knots when loaded to 14,000 lbs.
"Weight is kept to a minimum, and the performance data included with the boat spec sheets graphically illustrate what happens to potential boat speed when you pile on weight: It drops from a max of about 14 knots at normal half-load displacement of 14,000 pounds to 10 knots all up with full tanks, full complement, and all the goodies heaving it up to 22,000 pounds."
“Sailing with my children
we reached 21 knots boatspeed under main
in about 26 knots of wind
, it’s incredible”. Dave Penfield, ATLANTIC 42 owner.
Below is a another photo
from an owner on a big old heavy Atlantic 48.
Off topic....do you ever have complaints about bridgedeck clearance wave slap from the large low protrusions in the hull for your double width beds? I just cannot imagine it isn't a Hallo IDRhawke
I did not do the write up in the cruising world
I do know that we have hit a top speed of 26.9 knots on almost flat water with 34 knots of wind 130 degrees app.
The best day ( 24 hours )was good for a little over 440 NM
The draft is almost 2 ft more with the keel
but 4 inches less in the dagger board equipped version.
The bridge deck
slamming is almost non exhistent and that is largly due to the light weight so the waves gett followed better.
The protrusions have 550 mm clearance with a half loaded boat and that is plenty.
Unless you load up your complete family
, full water , full diesel and all the foad and stores for 2 months on the water you will never reach 22,000 lbs.
Just calculate with me
an empty weight for the electric
version of 5800 kilo or 12,800 lbs
75 us gal water 280 kg or 600 lbs
75 us gal diesel 230 kg or 500 lbs
and 4 crew o 550 kg or 1200 lbs
makes a total of 1060 or 3300 lbs
for a total of 6860 or 16,100 lbs total weight now if you make an ocean crossing
add another 800 kilo or 2000 lbs and you are still 4000 lbs short of our recommended weight
I have attached 2 pictures taken during a test sail by a customer of 21.5 knots , unfortunately when moving at 26.9 I was holding all the lines and no opportunity for a picture but it will come.
