No chafe on the sail or the rigging
Make sure the sail edge is protected from UV. When we came back from our 1 year cruise I had to replace the edge material of most of the sail
Lowest relative wind ~80 but requires pulling the tack down
Max relative wind speed was >20+ kn which I don’t recommend and it was not under my watch!
I think the size of the sail is good for me.

Hi Eric, we are also considering purchasing a porta bote.  What model and size do you have and how do you store it while underway? Would it be possible to post a photo showing the dinghy dogs.
Thanks,
Elaine and Michael

Bill, I agree with you, we have not needed to use our dinghy to propel us yet,but review how we would do that,in case we need to deploy in an emergency. I also have rescued a sailboat just before it was going up on a reef on the south coast of Grenada with my rib and its 18 hp two stroke. We also dinghy miles to snorkel and get groceries . Our 10.5 aluminum rib only weighs 98 lbs. ,we love it and it can do 25 to 30 mph in flat water ,just measured by my brother next to me on his jet ski the other day. BTW, we store two six gal. fuel tanks tied to the stanchions ,one is normally in the dinghy.

One downside is that what you have will not propel your boat to safety when necessary. If you have considered this and are OK with it, fine. But, if you haven't considered this, you need to re-think. You are going to places that you will need to self-rescue, and/or move your boat when you have no wind and no motor. It is hard to beat all of the advantages of a traditional RIB with a 10-20hp 2 cycle motor. I know of 2 SMs which were moved away from dangerous situations with a dinghy lashed to the stern quarter.

Hi all,
Last year we built a 11.5 ft sailing/rowing dinghy in hopes that it would work as a tender instead of carrying gasoline and gasoline motor(s).  RIBs are nearly impossible to row, can’t sail them, but they are very stable and carry 4 people easily.

The Dink we built is a Chesapeake Light Craft PassageMaker design that was originally sold as a nesting hull.  It’s 11.5 ft LOA , rows easily, and sails well.  When both parts are bolted together it only weighs ~95 lbs.  Sounds great so far, eh?

Here are the down sides:
*It doesn’t truly nest.  So we’re now storing 11.5ft of hull in two parts.  The bigger aft part sets nicely on the aft deck,  we weren’t comfortable lashing the bow section on the forward deck, so it ended up on the aft deck over the lazarette...so we can’t access the lazarette at sea without moving it.

*It is so lightly built that it bounces around pretty violently when alongside Kristy in any kind of chop.  It is also under built and we had to add strength to the bulkheads where the pieces bolt together because of cracks that developed at the joint between planks and bulkheads.

*The rig is a gunter style Marconi sloop with a small jib.  It takes about 45 min to rig and derig.  It sails well but can’t be reefed as currently set up.  With the gunter spar it would take a major overhaul to rig for reefing and it would be an involved process, not something that would be easy and quick. When rigged and not sailing the boom is in the way of rowing.  

*It will carry 4 adults, but doing that and sailing would be impossible, I think.

We bought a Torqeedo electric outboard which pushes her along adequately, but it isn’t built tough enough for daily use in salt water.

i guess we will have to go back to the RIB and gas outboard.  Hoping someone out there has experience with a great nesting dinghy that’s truly built for use as a cruising tender.  There are a couple others that look better than the CLC PassageMaker but probably have many of the same issues.

Any thoughts greatly appreciated.

Hi Willem
No issues with the end cap.
Everything Maud sent fitted perfectly EXCEPT the woodruff key!
The slot in the new gear was smaller than the old one, so I filed the key down to make it fit.
Alexandre (NIKIMAT) had the same issue but he had the slot in the gear re-machined to make the key fit.
Otherwise no issues.

Hi Alan,

Yes, I know all parts of the kit need to be installed. That was done last October except the end cap.  But dit the end cap fit on the foot of your bow thruster or did you had to drill other holes into the cap? Have a look also to my reaction to Bills comment.

Kind regards,

Re: Bow thruster seals

Alan Leslie
 

When we first bought the boat we had leaks from the bowthruster in heavy seas.
After haul out and replacing all the seals and adjusting the lifting mechanism as advised by Bill, Danny et al, we have not had any leaks in 6 years now.
We replace all the seals every two years when hauled out for antifoul, C-drive service and bowthruster, and no issues.

Re: Gears of bow thruster worn out after 12 times of use, two questions

Hi Bill,

After discussions with the mechanic here in Preveza and phone calls with Maud at the Amel factory the following is now clear (to me):

Last year in October I experienced suddenly a screaming noise and no thrust anymore. I went to the Ascar Boatyard in Cartagena Spain and after opening they showed me worn out gears, not having grip at each other. So I ordered the kit from Amel and the mechanic of the Ascar boatyard experienced problems with the installation of the new end cap (part of the kit). The screw holes in the cap not matching the holes in the foot and also a difference in diameter between the old cap (just fitting) and the new cap going in very easy (new cap 84,02 mm and old cap 84,34 mm). So he used the old cap, but did nit notice that also the inside of the new cap was 0,25 mm more towards the bearing, compared to the old cap. He installed without checking the play by pushing and pulling the propeller hub after installation. The mechanic here at the Aktio Marina boatyard told me that there was a very big amount of play causing the premature failing of the gears. So he suggested to use spacers to control the amount of play. After consulting an Amel technician, Maud told me that using the new cap of the kit will result in a correct, very small amount of play between the gear wheels, but using the old cap will result in a premature extreme wear of the gears. She also told me that it is possible that the screw holes in the new cap will not correspond with the wholes in the foot and that also the diameter of the new cap is somewhat smaller than of the old cap. The Amel technician agreed that a solution can be reached with using the old cap with placing a spacer of about 0,25 mm against the bearing to correct the difference in inside depth compared to the new cap.

I still find it a little strange that Amel is supplying a not fitting end cap with the kit they sell to replace the bearings and gears of the foot of the bow thruster. She offered me a 20% discount on the price of the new kit.

Best regards,

Willem Kroes

Re: Petrol questions/survey

Hi Alan,

I'm with you on this. Until you've seen big seas breaking over a boat you just cant imagine the power in them. Eric knows more about that than ost I think. We store our 4 jerry cans of diesel and one of outboard mix in the port locker out side the cockpit. No ignition source and a lid not locked down so in the impossible event of an explosion the lid would fly up, minimizing any damage, so long as you were not sitting on it at the time. grin

Fixed Port Lights - Maramu

Andy Croney
 

Dear Amel Family,

 a small question; 


We intend to replace all four fixed port lights in the coming months .

We see that the stainless cover / fixing plate is held with screws , not bolted through and there appears to be a “rubber “ gasket.  Doesn’t seem to be silicone ?  .

Can anyone advise what material was used by Amel?  

is there anything we should be aware of before attempting this project ????


Please see photo below by way of illustration:- 


Thanks again for all support, very much appreciated.

Forward holding tank inlet clogged- project summary

Thomas Kleman
 

Wow. Much more difficult day than anticipated. Clog in the outlet riser to tank resisted every tool so had to ram through it using prop puller to force steel rod through to top of bronze pipe. Quite messy despite careful prep. I'm still fearful that part of clog remains so I'm getting some muriatic acid in the morning to flush through the system. Bill Rouses drawing  of the holding tank plumbing  was important; needed to be sure the end of bronze pipe in tank didn't contain a bend, which would have complicated my brute force solution.

A couple of times we totally lost all wind and furling could be done poorly and had to be redone as soon as we got back some wind.

Re: supplemental downwind sailing configuration for Super Maramu

James Cromie
 

Looks great. This is exactly what I’m looking to for!  Thanks for your measurements.  It looks to me like you’ve had the sail designed so that the foot easily clears the bow pulpit, while your furler is down below and I’m assuming it has adequate clearance from the headsail furling motor housing.  

Any troubles with chafe up at the masthead?   

I’m thinking of using the Profurl Spinex 2.5 which will accommodate a sail up to 130 sq. m. 

How high into the wind have you used the spinnaker? 

Many thanks,
James

FWIW, I had a set of gears machined by shop in NZ.  Works well although we use it rarely as we anchor most times.

Dear Amelians,

After installing a new kit with gears and bearings from Amel last October and after using the bow thruster not more than 12 times the gears are worn out like in October.

The diagnosis of the mechanic with some experience with Amel boats is that there was too much play between the vertical and horizontal gears and that spacers or shims are needed add to the bearings in order to set the gear wheels in a proper fixed position.

First question: is Amel selling a set of shims with different thickness (0.10 to 0.50 mm)?

Second question: What is your opinion about what the mechanic told me?

Re: Gears of bow thruster worn out after 12 times of use, two questions

Willem,

Can you post some pictures of your gears to show us the wear that you are seeing?  I changed out the bearings on my bowthruster this past winter for no real reason other than the fact that they were 15 years old.  I was surprised with how loose the gears fit together and found that there was a lot of "play" or "slop" in them.  However, there was no appreciable wear on the teeth.  I sent a video to my surveyor Olivier Beaute showing the amount of play and he said it was what he would consider a normal amount of play.

Re: Gears of bow thruster worn out after 12 times of use, two questions

Willem,
When we replaced bow thruster parts in Fiji last year, Amel told us this :

-Bowthruster mechanism (see photo): the parts composing this mechanism cannot be sold separately as everything is perfectly adjusted together (especially the gears and shaft and black cap) to avoid any failure in the system. The price is 582.40 euros without taxes and without transport.

I am sure you can find the roller bearing locally. I can give you the exact SKF reference if needed.
