I recently re-filed my PHRF certificate to get +6 seconds for a roller furler.
Subsequently, I just had the luff my Mylar/Kevlar 155 cut down to fit on the
furler. My sailmaker cut a bunch off the foot.
I was chatting about loosing the sail area with one of the really good sailors
in the clu
Dennis,
My limited understanding of aerodynamics is that if the foot is not on the
dock then the higher pressure is allowed to "leak" under the foot to the
low pressure side, diminishing lift. That's why they now have tips on
airplane wings. If the cabin causes upward deflection, that may be mor
Dennis: Now if you want another 9 secondsditch the spinnaker pole and
declare “no pole” and go straight to your ASYM…Ron C.

Being concise ...
The setup on the older C&Cs is fairly bad for bulk charging of a larger house
battery bank.
1) Wiring
The path had the alternator output running the distance back to an ammeter on
the instrument panel,
then back usually to the starter post, then possibly through a switch and
Calypso's headsails were also cut for a furler with the higher foot, now about
18" off the deck.
We still get a significant "speed bubble" in the main at the mid to upper wind
range for the light and heavy #1s. The bubble shows up 6' to 25' (off the
deck) on the mainsail.

Martin,
"end plate effect" is what I was thinking about. The deck is the end plate
for a sweeper.

I don't know about your PHRF area, but Chesapeake requires that the furler
drum is above deck AND you have the UV patch (heavy cloth) on both the foot
and leach of the sail. Then you get the six seconds.

Thought a furler was 3 seconds, not 6? Have to check our PHRF site.
Less area but the higher foot makes it easier to skirt over the lifelines, too.
When ours gets caught, I have the crew tension the sheet and I tap the
lifelines from the wheel and the sail rolls right inside, and they fine tune
Thanks to everyone who chimed in about these issues--a good example of the
expertise on this list and your willingness to share it! It's also an
illustration of the adage "...be careful what you wish for".
There are so many ways to address my mixed battery issue that my head is about
to explode
Gary,
You are right about the above deck furler. I'm in the Gulf Yachting
Association (gya.org) Here's the rule:
"The PHRF committee may allow +6 seconds per mile in rating for a roller
furling headsail and +12 seconds for an optional IN-MAST roller furling
mainsail. Boats must have a SA/DSPL le
I’m going to insert a comment here on keeping perspective with PHRF ratings. I
recently had a conversation with an individual affiliated with our local
ratings and he commented that 3 secs equates to approximately 1 boat length for
every mile raced. So as nice as it is to get 3 or 6 secs, IMHO
My boat came with white plastic tubing on the babystay, which I am told are
called shroud rollers. I was told that it protects the genoa while tacking.
The tubing itself is cracked in various places and I am thinking of replacing
it, but can’t find anything similar online. Does anyone know a
David,
I'm pretty sure I've seen them in West Marine stores in a variety of sizes with
caps.
All the best,
