[Rhodes22-list] Planing

[Bill Effros]

Pete,

Q2 -- My boat has no trouble reaching 6.25 kts, both under motor and under
sail.  This is greater than the predicted hull speed, but not planing.
Under small craft warnings conditions, I have planed at 7-9 knots for hours
at a time, after factoring out the current (I've hit 10.5-11 over ground
while using the current).  At lesser wind speeds I have seen boat speeds in
the 7.5 kt range, and I have thought I must be planing, but things tend to
get complicated under those conditions and I have not been able to factor
out current.  I sail on Long Island Sound where the current is often around
1.5 kts so it often makes a difference, both when measuring speed over
ground and speed through the water.

Jay,

You've got enough wind, and little enough current to be able to test planing
almost any time you go out.  The main must be silly small, and you must play
with a 175 jib so that you heel as little as possible and all the force goes
into driving the boat forward to break the hull out of the water.  I find it
easier to do this single handing, because, as Roger mentioned, it requires a
very fine balance of a lot of powerful forces.

Roger,

If you put hydrofoils on the bottom of a Rhodes, and a large enough motor on
the transom, would it be possible to get the boat up onto the foils?

BTW did you notice that the New Zealand America's Cup boat is using a
(substantially more sophisticated) variation of the idea we discussed last
year of reversing and attaching a dinghy to increase the length of the boat
at the waterline in order to increase its maximum speed through the water?

Ahoy fellow list members!  I just joined you and have a few questions, for
any who would care to respond.

I've been racing my Tanzer 16 dinghies for 22 years, but no BBs.  However,
the idea of gunkholing on the Chesapeake or the NC estuaries closer to home
is quite appealing.  Maybe, with some luck and if there was no racing
involved, I could convince Tana to come along...

My father owned a Rhodes Continental more than 20 years ago on Lake Monroe
in Indy.  It was a great boat.

The Rhodes 22 looks very good to me. Here's what  you can help me with:

Q1    Is there a bulletin board anywhere listing used boats for sale?  Does
Stan make the market with his "recycled" boats?   Where should we look?

Q2    Do you know of anyone who has ever claimed to have "planed" their R22?
What speed was measured?

Q3    Under ideal conditions, say 10-12 windspeed and smooth water, what is
the most probable sailing speed?

Q5    Are these boats good ghosters?

Q6    Do R22 people get together often for group trips?  Is there a "class
association"?

Q7    What's the best launching area on the western shore of the Chesapeake
to depart for St Michaels in late June?

Q8    I am also considering a Santana 2023.  It appears not nearly as
comfortable as an R22, but likely quite a rocketship.  Any advice about
that?

Thank you for sharing your experiences and advice.
