I have a Bic Astro Rock and I'm woundering what is the biggest sail
I can use. Also what size and type fin should I use with it. I'm 6'
tall and 175-80 lbs. I sail in 10-30 kts. on a lake that gets choppy
after about 12 kts.
 I've been told to get a bigger board and use a 7-7.4 sail. I thought
that I saw someone say that they used a 7.0 before. I'm sure that it
has a lot to do with the person's size.
 Thanks for any words of wisdom or speculation.

I have an Explosion (roughly the same size) and normally sail with a
7.5.  BTW, I weigh 210 lb.  Much more sail and I would probably start to sink.

i routinely use a 7.0 and my 180lb friend uses a 7.3.

I used to have one before it was ripped off.  I would use a 7.5 on it
quite often and I still do on my replacement Presto, although I hate
using such a big sail.  I have a friend that sails his Rastro with a 7.0
a lot.  I'm 6'3" and 195 and he's 6'8" and 205.  What kind of fin are you
using  now?  Chances are you need to go bigger for the bigger sail,
probably around 14".

Hi
 I own a '91 Astro Rock, it was my first short board and is still my light
wind board, I weight 180-190 lbs and have been sailing about 5 years.  
I regularly use a Gaastra 7.5 M CS Pro, Dynafiber XL carbon mast and NP boom
to get planing in light wind (10-15 mph), with a 15" pointerfin.  This is a
big rig but is also very light for its size ( it helps make-up for my body
being the opposite!).  I'm very comfortable on the A-rock since I've sailed it
for so long, so that helps with the big rig.  I seem to be able to plane as
soon as anyone else does and before many, although I do seem to fall off a
plane sooner than people with more modern equipment.  I get a lot of practice
with light air here in the Chespeake Bay, especailly during the summer, just
remember to keep the board flat (ie hang your weight off the boom and use your
feet to keep it level sideways) and sheet-in.  You can plane even sooner if
you learn to "pump it up".

PS To those former A-Rock owners;

I'm pondering an upgrade to my A-rock.  I'd appreciate any opinions as to
modern replacements for use in 7.5 to 5.7 M conditions.  I'm looking for a
livelier ride, good planing ability and a modern cavity-type fin box ( so I
can put in a long fin without worry).  Or should I save My $ and remain happy
with the A-rock?

Thanks

John Q.

a mistral explosion provides an improved ride, higher speeds and a cavity
box.  A used one might cost about $500-600 depending on condition.  the
explosion II should be available soon (120L instead of current 130L), but will
probably cost around $1200.

My dad and I are both about 6' 180 lb. He has my old A Rock so he
has two now. He has sailed it with an 8.5 but prefers putting the
8.5 on his Seatrend 99. This on a small lake in Michigan.
With a 7.5, he's happy with either board. I just talked to him
last night - he sailed his A Rock yesterday with a 6.1 (10 mph with
gusts to 20 so mostly underpowered) and said the board is feeling
really huge now that he's put some time in on smaller boards.
In my opinion, a good modern 6.5-7.5 (or 6.5 and 7.5) is perfect
with that board for lake sailing. We have used 13" pointers (an
11.5" Finworks H12 felt small), 13.5" low aspect pointers, and
more recently a 14.5" True Ames Series II G10 blade. The big
low aspect pointers (H16 and T.A.High Volume II) are easy to sail
and seem to work well both under and over powered. Not as fast, but
not bad either with the big size sails we are talking about.
I sailed the 7.5 on the 14.5" blade when I was back a couple of
weeks ago and it worked very well. The biggest differences I noticed
were in the booms -- light, stiff booms (carbon) are a must. I also
played around with different masts in the 7.5 and liked a 460/25
constant curve better than a 465/30 flex top but both worked pretty
well. (Aerotech Pro Race 7.5 from 1992). We've also tried a 500/28(MCS)
constant curve and 500/28 flextop. These seem a little too stiff.
Probably the recommended 480/27(MCS) or so would be best for this
sail, and this size sail in general. The 460/25 that we have is a
Fiberspar World Cup 1-pc. with boom reinforcing that permits running
alot of base extension. We have a Fiberspar tube that extends a
mast 47cm and a similar ART tube that is adjustable and can go much
longer than 47cm (!!!). I feel pretty comfortable using these extensions
on the Fiberspar 1-pc. but not so comfortable with some of the other
masts we have. E.g. just noticed a bend in the aluminum ferrule(?) of
the North 2-pc. flextop.

I talked to a couple of guys sailing Windwing Twin Cam 6.7's on the
bay last weekend (Sat. not Sun.!). They look like great sails.
My dad's 6.8 Windwing Race (1993 proto) is _really_ sweet and has been
his main A Rock sail for a couple of years now. One good sail is better
than two crappy sails. Good luck.

try a Rainbow 15.5 " pointer. it should easily work with a 7.0m2

The Astro was my first short board and I still use it with a lot
of satisfaction whenever it's not windy enough for my Electric Rock.
I'm 65kg (145 lbs) and the biggest sail I use (most of the time) is
a 6.0 (2 cams) with a relatively small fin (32 cm (12.8")).
I found that if I can't plane with that, (almost) nobody else does,
even with bigger sails.

My largest sail is a 6.8, and my Astro Rock handles it well.  I think it's
capable of handling quite a bit larger.  I am a bit smaller than you are
(5'9"/165#), so bouyancy may be an issue as well.

As for fins, I use a 14" pointer (Hydrofoil) with my 6.8, and it seems to work
OK.  You'll need a big fin for such a large sail to get it planing.

Just my $0.02.

Regards.

I sail my Astro Rock most often with a NP V8 7m^2 sail, using a 14"
blade fin (which by now is down to 13" due to numerous beach-starts).
Cheers.
