641.1 | one view ... | MSCSSE::BERENS | Alan Berens | Tue Sep 08 1987 12:36 | 31 |
| My cruising experience (Maine, Nova Scotia, and Bermuda) with our 32'
cutter suggests to me that a cutter rig is ideal for shorthanded, long
distance sailing. We have found that a combination of Yankee jib (100%),
staysail (70%), and mainsail (three reefs) works well from 10 knots 'til
storm sail time. We very rarely change headsails, usually from 130%
genoa to Yankee or visa versa. We haven't yet needed our storm jib or
trysail. I would not choose a sloop (or a ketch or a yawl) for long
distance sailing.
While all of our headsails are hanked on, I might consider roller
furling for the headstay were we to get a 40' or larger cutter. Note,
roller furling, not reefing. And I would use one of the (very expensive)
models that worked well in the BOC race. A sailmaker from Doyle, when
pushed, agreed that hanked on headsails are probably better than roller
reefing/furling for shorthanded, offshore sailing. With a sloop, you
will sooner or later have to change a headsail. My impression is that
there is a limit to how much you can roller furl a headsail successfully
(say a 130% genoa to 100%). For winds over say 30 knots, a 100% jib is
likely to be too large. Handling even a hanked on 100% jib in 30 knots
winds and rough seas by yourself is difficult.
My view (not shared by others I'm sure!) is that roller reefing/furling
is acceptable for coastal sailing where there is little probability of
being caught in weather bad enough that headsail changing becomes a
major problem. My one personal experience with roller reefing some years
ago (a Hood system with a Hood sail) is that yes indeed, the sail cannot
be kept flat enough for good performance.

BTW: I like it. Four seasons, no problems. It doesnt permit proper
shape when "reefed", but the extent of that changes from sail
to sail and sometimes furler to furler. North has an interesting
concept, anyone tried one yet ?

641.3 | sails matter, not so much the system | RDF::RDF | Rick Fricchione | Thu Sep 10 1987 09:58 | 32 |
| The North system sounds like another gimmick/hype to me. Most
sailmakers have panned it, saying it does'nt do any good once the
first 6 inches of sail are rolled in anyway.. Its kind of the same
idea Harken had with the double swivel, trying to get the belly
of the sail to roll up first, then the ends.
I have had good luck with roller reefing for the last two years.
Prior to that I had a headfoil two and used to haul genoas and jibs
out on the foredeck in the middle of Buzzards bay with the boat
bounding and leaping.
The most important thing to me is the sail, not the system. The
sail has to be cut to allow roller reefing. You can't take ordinary
sails and reef them down, they will bag out, lose shape,and wear
much more quickly. Newer designs allow for things like bi-radial
construction and foam luffs that allow for flatter sails and better
shape when reefed. You still can't take a 130 down to an 80 and
expect it to keep its shape, I've found about 100% is the lowest
I'll take it with decent shape. I also carry an 80% bi-radial
that can be reefed nicely down to almost storm jib size. In both
cases the boat points nicely to windward, and has decent sail shape
on both tacks (roller reefed sails sometimes bag up more when you
are on the tack opposite the way the sail rolls up).
I wouldn't go back, the advantages to me are in convenience, safety
(I sail mostly with my wife) and the need for less sails. Often
times you just need to take the "bite" out of a 25 knotter by taking
in just a little. I'd rather not change sails in that situation.

641.4 | RR & BACKSTAY | CURIE::DONOHUE | | Thu Sep 10 1987 13:11 | 6 |
| I went to a Harkin Furling system this year. I had a 130 converted
with a luff pad and an 80 converted without the pad. I've yet to
use the 80. I've found that the sail shapes better when reefed
if I tighten the backstay. This flattens the sail out quite a bit.

Interesting, John.
Tightening the backstay should also tend to flatten the main and
reduce it's power. Sort of a demi-reef.

641.6 | always tradeoffs | MSCSSE::BERENS | Alan Berens | Mon Sep 14 1987 11:37 | 8 |
| Tightening the backstay is fine if you can do it easily, but once your
boat gets much over 30', an expensive hydraulic tensioner becomes
necessary (yes, there are some mechanical tensioners, but they are slow
and inconvenient).
I guess whether you choose roller furling or not depends on how much
cost and complication you are willing to accept to make sailing easier.
|
641.7 | more on backstays | CURIE::DONOHUE | | Tue Sep 15 1987 17:00 | 11 |
| I wouldn't want to give up my backstay adjuster. As Ed pointed
out, it is useful for flattening the main. In many cases the use
of the backstay and or traveler eliminates the need to reef or change
sales.
I would rather have a backstay adjuster than a stereo or oven.
But those are my trade-offs.

641.8 | twin forestays ?? | RDGE00::DAVIDW | Dreaming of lip smacking at Cactus | Wed Sep 16 1987 06:56 | 13 |

Thanks for the pointers on roller jibs , I must admit that I hadn't
appreciated that the sails were primarily roller furling with a
limited built in reefing ability . Maybe a solution is to have
twin forestays and have a roller furler on one stay for up to 25
knots or so , then hank on a number 2/3/4 on to the other stay
for winds stronger than that . Has anyone tried such an arrangement
??? IS it practical ???
Be pleased to hear your opinions

| RE: -.1
Very common on long range cruisers, either as a cutter rig, or in
some cases resembling a sloop (stays within a foot of each other
or side by side). I think it fits the cutter especially well.

By twin forestays I assume that you are referring to side-by-side
headstays. I've no personal experience with such a rig, and have never
talked to anyone who has. However, as I recall, Hal Roth tried them and
stopped using them -- too many problems. There have been other published
reports of less than satisfactory performance. Roth strongly recommends
a cutter rig (see 'After 50 000 Miles'). So do I.
One problem with what you suggest is that double or side-by-side
headstays will only have half the tension of a single headstay. This
will result in substantially greater headstay sag under load and will
make it virtually impossible to get enough headstay tension for proper
headsail shape. Unless perhaps you have a separate hydraulic tensioner
for each headstay and only tension the headstay that is in use. Navtec
would be delighted to take much of your money for this custom engineered
installation. There is still the problem of the headsail chafing on the
headstay not in use, particularly down wind.
Oh so rare is the good idea that doesn't have some less than ideal side
effects!

| Should you still be unconvinced that roller reefing is a dream,
then give me a buzz next time you are Geneva bound, order up some
of our local "Bise" (F7-8) & we can then go & try out roller-reefing
together. Rgds, Nick

641.12 | Euro-reefing continued ... | AYOU17::NAYLOR | Purring on all 12 cylinders | Thu Apr 14 1988 10:36 | 9 |
| Last year I sailed the Ionian Sea (Greece) for 2 weeks and with
winds that went from force zero up to 8 and back down to 1 or 2
within a period of a couple of hours, I became TOTALLY convinced
that serious cruising requires the use of roller reefing.
Racing .... now, that's a different story ....
