Alan,

You really get a SM to tack through 90 degrees measured by COG?  Wow!  Who’s your sailmaker?  That’s a COG tacking angle I’d expect from a J-105!

What apparent wind angle do you have to pull to get that, and how do you do it?

In normal sea conditions, I expect to hold 35º to 37º to the apparent wind, which gives us about a 50º+/- angle to the true wind, but we haven’t counted for leeway yet, so I normally think I am doing well with 102º to 105º change in COG on a tack. If I get to 110º in small seas I know I am getting sloppy on my sail trim.  My autopilot tweaks the course while beating to optimize VMG, and it always settles down very close to those numbers--if the seas aren’t too rough.

In perfect conditions (10-12 knots true, flat water) I can pinch a little more out before the keel stalls and I start going sideways.  I’ll expect to get a little better with new sails, but nothing like what you see.

Hi James,


There are lots of messages in here about inner forestays...and pictures.
Ours was factory installed and is a furler on a permanent stay at the top spreader with dyneema running back stays. The furler is anchored fwd of the windlass to a 13mm SS plate under the deck that runs under the deck from the windlass to the bow fitting.
I'll try post some track pics from Maxsea that show the 90 degree tacks !

Perkins Prima M50 (Volvo MD22) fuel consumption on KALI MERA varies from 1,8 l/ hour with 1500 rpm (motor-sailing) and goes up to 4l/hour with 2300 rpm.  As we are not in a hurry with no wind we cruise with 5kn and ~ 1800  rpm and use about 2,2 l / hour.    If the prop is really dirty than add about o,5 - 1 l / hour

Bill,

   I am unfortunately not on my boat, however as I recall, on the bottom of my swivel are two eyes that line up with the two grooves in the furler.  These two eyes are the attachment points for the heads of my headsails.  One of will be used in the normal way with the head of my 150 lashed or shackled to it.  The remaining free eye which the head of the ballooner would normally be attached to if hoisted with the 150 is where I plan to hang the top block.  This should place the lift point directly above the slot in the foil for the ballooner.

Of course,Joel.  That reminds me of two other rules I've learned:

The 50-90 rule:  if there are two ways of doing something and you're not sure which is right, you have a 50% chance of getting it right the first time...and a 90% chance of getting it wrong.  It is amazingly accurate for me.

The boat list rule:  if you have 10 things to do, and you do 7 of them, there are only 8 on the list.

Hi Ric.  Yes, and thank you for that.  I carried the jerry cans on deck the first few passages South and back North between the Chesapeake and the Caribbean, but never needed a drop of fuel from them.  Finally gave them to a boat going transAtlantic.  If I ever do an ocean crossing, I might add another tank, just not sure where.  Kristy lists a little to port already, and is a little stern heavy, so the port deck locker and aft lazarette don't seem ideal.  It may be most sensible to carry cans on deck on the starbord side, since I wouldn't need or want extra fuel once I crossed.

I also average a little under 3L/hr when motoring.  I usually motor at ~2000rpm and motor sail at rpm enough to average 4+kts.

Bill,


   I appreciate your suggestions on the other possible downwind setups and am sure that your intentions were as stated.  I have found so far that usually when I think  through the options to improve something on my Amel that I usually come to the conclusion that the original design was either on target or certainly close enough to satisfy my needs.  In this case, I can clearly see that the upgrades to the Santorin and SM which allow instant furling of the twin headsails to be very desirable.  I think that I have a fairly simple idea of how to get my boat to function like the upgraded models that is easily reversible if I don’t like it which I plan to try first.  If I don’t like the results, I would like to look into changing the foil and adding the lock/unlock mechanism to do the full upgrade.   I am not so sure that this upgrade would actually cost more than any other new system that I can think of..does anyone know how much a new set of foils run?   This example of the differences between the earlier and more recent boats and shows me the natural and healthy evolution of these boats.  It actually surprises me when I look at boats that are 25 years older than Sueno and realize how much has remained the same, which tells me that either the designer got really lucky early on or maybe he was a pretty smart guy!  ( I am thinking the latter  (grin))  Regardless of how far Henri brought these boats, of course there will be room for improvement in some areas so I welcome new ideas.  I am however becoming more reluctant over time to make changes until I am really sure and with downwind twin poles on Ocean crossings, that is new stuff for me.

The original question (which I was trying to address in my comments) was what could be done to make a boat that was NOT rigged with a triple slot foil come as close to a fully developed Amel downwind rig as possible.

I hope if what I wrote was read carefully, you would see nothing was suggesting anybody change the system that eventually became standard on the Maramu and SM.

   Yes, I know that the twin poles have been around for a long time but I never considered them seriously due to the complications of quickly dousing if needed for a return to windward.  Amel seems to have mostly solved that problem and the reefing ability is a big plus in my book.  I think that I might have a solution of how I can use my existing setup but if it doesn’t work out I will look into upgrading the boat to the Santorin/SM arrangement.

James,


For a downwind rig without the $$$$ of a new foil, talk to Dave at Island Planet Sails.  He has suggested a pair of nylon ballooners on a rolling rope luff that would sheet through the double wisher poles.  I don’t know if he has actually built one, but it might be worth exploring.

It sounds like it would be easier to set and do everything the standard Amel rig does… except…  I doubt it would be usable partially reefed.  But might be worth investigating.

Poled out twin jibs have ben used by tradewind passagemakers long before Amel started putting them on their boats.  There are lots of ways to skin this cat. Amel's innovation was to make it easy to set the reef the sails and handle really big whisker poles.

Ian, Linda and the many others that responded to my questions about new sails..


   Thanks to all for the great input.  After sleeping on all of the information, I find myself drawn back to the original design concept of a 150 Genoa,  it just makes a lot of sense.  It just seems like the go to sail  the planned downwind passages using the twin poles along with a ballooner.  The addition of foam or some other bulking material to the luff to enhance the reefing qualities makes a lot of sense.  I have seen the permanent creases due to stretching that are apparently caused by rolling a shaped sail onto a straight extrusion and then loading that sail.  I don’t see how the 150 would be a good choice reefed as a storm sail and I would like to have aboard a smaller nicely shaped easy to tack jib for windward sailing and higher winds that would be more suitable as a storm sail. So it seems that I will just need to make some room to store one of these sails while the other is in use.  I wonder if by using the Hydranet if the 150 can be made a bit lighter so as to be easier to change with the understanding that the heavier smaller 100-120 would replace it for the expected parts of the trip where the winds will be strong?  Yes, there would be times when sailing through an acceleration zone etc. where I might be caught with the 150 in too much wind so I would need to be careful to not make the sail too light. A lot of the weight of my old 150 seemed to be in the sun cover.  Are there lighter UV covers available?

   I have a question about running twin sails on my Maramu using the twin slot extrusion.  It concerns me a lot having the need to lower the ballooner to furl due to the possible need to quickly turn the boat back upwind…  The concept of being able to furl both the 150 and the Ballooner seems worthy of adding to the boat from a safety standpoint if nothing else.  I was wondering if anyone has ever used a halyard running from the furler head to the furler tack attachment to hoist the ballooner and whether this work in lieu of the snap ratchet upgrade?  I am envisioning a continuous halyard line of small diameter using a small block at each end(high strength Spectra perhaps) that would roll up with the two sails.  The ballooner is so light and easy to raise on my boat that I don’t see why this could not work but what do you think?   The only other option seems to be to hoist both sails together on the same halyard which would be a mess dropping both at the same time, probably as the wind is coming up…  

   Ian and Linda,  Yes, I have seen the Santorins and think that they are lovely boats!  From a distance it is sometimes hard for me to tell them from a SM.  It is interesting to look at the various designs and to see the evolution of these boats.

The Santorin is a scaled down SM minus some kit because it has less room eg gen set, freezer, washing machine etc....
So the rig is identical including the triple groove foil and furler with the snap ratchet for the ballooner.

The foam luff... Because of the 'shaped' cut of the Genoa, when it furls the centre section does not wrap as tightly as the top and bottom. So the centre bulges more, leaves creases across the sail and does not drive as efficiently.
Three strips of foam padding(in gradually shorter lengths) are stitched in down the luff. As the sail furls this new 'bulge' gathers more of the centre of the sail giving a better shape that drives better in stronger winds.

As Bill says, it's an omission that should be corrected.

Hi Ric.  Yes, and thank you for that.  I carried the jerry cans on deck the first few passages South and back North between the Chesapeake and the Caribbean, but never needed a drop of fuel from them.  Finally gave them to a boat going transAtlantic.  If I ever do an ocean crossing, I might add another tank, just not sure where.  Kristy lists a little to port already, and is a little stern heavy, so the port deck locker and aft lazarette don't seem ideal.  It may be most sensible to carry cans on deck on the starbord side, since I wouldn't need or want extra fuel once I crossed.

I also average a little under 3L/hr when motoring.  I usually motor at ~2000rpm and motor sail at rpm enough to average 4+kts.

Ian is right, but I tend to motor at 2000 to 2200 rpm. I often motor sail for my 4 knot rule at lower RPM. I keep a fuel log as well. Bottom line is that 1 US gallon/hr is my safety number and voyage average is .75 gal or 2.75 liters/hour. I have installed 2- 35 gallon tanks in the aft lazzarette with a fuel transfer pump in the engine room that refills  the main tank instead of jerry cans on deck or spilling fuel. Yes it is heavy at first, but I don’t have to handle, drag around or buy jerry cans. Kent got some of them.

I haven’t done a detailed analysis of fuel consumption. We have the Perkins Prima 50 on our Santorin. I believe we get around 2.75 litres and hour, but our engine use varies greatly from running at 1500 revs for the the belt driven watermaker pump, to motor sailing at 1800 revs, or punching a head sea and wind at 2,200 revs. We try to avoid the last one!

I have worked on a range of 700 nm on a passage, and it seems to hold true. Because of the shaft alternator we find all our electrical demands are met when sailing above 5 knots. We filled up in Cape Verde before crossing the Atlantic and lasted the next 4 months before refuelling before lift out, we didn’t need to run the engine for battery recharging on the whole crossing. Because the Santorin lacks power hungry stuff like washing machines, freezer and air con the demands on the batteries are lower than the SM (hence no gen set as standard on the SN). Maybe other Santorin owners can chip in, but we use more fuel in Island hopping than on an ocean passage. We carried 100 litres of spare diesel which wasn’t required (but was reassuring).

Re: [Amel Yacht Owners] New sails

Ian,

   After I sent my last response to you I realized that I had made a mistake.  You did say sitting with your feet in the bow locker and I said standing…  The sitting position sounds like a good way to brace and I should be about the right height as well..I will give it a try.

   There is an eye at the tack fitting on Sueno with a lot of room to put several wraps of perhaps 1/8” line to secure the sail, so it would be quite easy to tension the luff of the sail in that manner.  That is a good idea to leave the tack loose initially and should make the tensioning easier.  I can’t imagine that the sail weights even 10 lbs. but there is some drag due to the wind load when hoisting.  I am glad to hear that you think that this might work,  I don’t loose much if it doesn’t.

Best,

Sitting with feet in the bow locker gives me a better downward pull on the halliard. It also means I can ensure the leach slides up the groove without snagging any sailcloth. Plus it's comfortable and leaves Linda in the cockpit to tend the sheets and steering.
Your plan may well work. Just an addition - I don't fasten the foot of the ballooner until last. It ensures the snap fastening engages properly, and then I tension the foot which is easy to do even with the boat on course and sail full. There is a rectangular s/s loop on top of the furled to thread the down haul through a few times to get a good purchase.
I'm not on the boat yet to send a photo, but if you fastened a snap shackle to the same place you could fasten your up haul loop to it and tension the foot afterwards. 
I don't know if the Maramu has this fitting, but it shouldn't be too difficult to have it welded on maybe?

Good luck.
