I've just gotten myself a DF 95 and I'm putting everything together, including extra rigs.

What is the breaking strain of the 0.6ml Dyneema line that is supplied with the basic kit, please?

I have some other Dyneema, but I want to make sure that it's strong enough before I spend time using it to build the extra rigs.

Cheers and thanks!

What i've found in the past is it takes 100-130 test spectra line to not slip in the bowsies under pressure,that strength would be fine for any rigging job.I don't know what test the supplied line is.

Hi

Thanks for that. Looked up 0.6ml Dyneema and found some good quality stuff (from New Zealand) which had a rated breaking strain of 70 kg (that's just under 155 pounds). Not sure what the quality of the line supplied in the kit is, though.

Cheers!

I have found anything under a 100lb test will slip in a bowsie when it's blowing.And as said earlier 100+ lb line is more than enough for any job on a model boat.Another tip is i use bees wax to stiffen the string to get it in a bowsie as a single line i use 130lb and that's a tight fit,i have seen some use a fine wire loop to pull in the string,this in my opinion will damage the integrity of the hole as you drag two lines through the hole,this in turn decreases the holding power of the bowsie.Also as time goes by and you discover what a boat likes i will eliminate bowsies on the forestay in preference of a fixed line,nothing to slip in a collision.I've won alot more races sailing the boat than fiddling with it before every start.

Scam Alert - AMYA has been targeted!


All, .....Scam Alert.......

I do apologize that my first ever post to RC groups has to be one of this subject. But my intention is to always keep the AMERICAN MODEL YACHTING ASSOCIATION (AMYA) in a good/positive light. Many of you on Facebook may have already seen this post this morning, so please accept my apology once again to repeat this on your fantastic thread discussion. My IT staff here at the AMYA feels we need to get word out that this company named "FUNDLY", as well intended it may seem, may be hacking into accounts and create these scam campaigns. Or it could be some low-life computer hacker in a basement having his 15 minutes of fame. Please be aware that the AMYA will continue to investigate this and we ask that you please help us spread the word of this internet scam! ................... Good Winds...... Ray Seta - AMYA President


----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

On a serious note: SCAM ALERT
It seems that ever since I have become President of the AMYA I have become a target, as some would say, on the race course! Sometimes I can actually feel like I have a target on my back around the race course. Well it seems that now I have now become a victim of an internet SCAM also. As you can see in the pics below, some one has set up a fake campaign with an internet fund raising company named "FUNDLY". Whether this is an reputable/legitimate fund raising internet company or not, I don't know. Please be aware that I, as the President of the AMYA, have now been made a victim of this scam. Please do not reply to it or contribute any funds to it's cause. Please help me spread the word to your local Club members that this is a SCAM! I can only thank a member of the South Daytona Model Sailing Club for bringing this to my attention last night and now I am currently spending my Saturday morning doing some damage control here. I can assure you that I do not have a neighbor named Eric and I have certainly have not been the first contributor of $2500 to his cause.
Again......please do not contribute to this campaign!!!!!!

Sail on with good wind!

Hi

Thanks for that.

I'm going to go to a specialist fishing shop to see what they have. I'm sure the braided Dyneema line that they sell would have the line thickness as well as the breaking strain.

Like you, I'm not a fan of bowsies - I feel they can slip when under pressure. While I was sailing Micro Magics, I eliminated all bowsies from the forestay. (Micro Magics rules are very flexible where it comes to rigging options.) However I have two concerns with doing this on the DF 95:

1. The rules state that the boat must be rigged up as per the manufacturers instructions (I saw an earlier thread in this discussion where someone had a separate bowsie for the forestay and the jib hoist and they were advised that it was not strictly legal). Happy for someone with a better experience in DF 95 rules to correct me on this one, but I'd like to try to stay with the strict "one-design" philosophy of the class - even if there might be better ways to rig them.

2. These boats appear to be rigged with a lot of rig tension (as opposed to the Micro Magic). Dyneema is a very good line material, but it will stretch after a while, especially under constant tension. I would want to be able to adjust it down the track when stretching occurs. I'm using a fibreglass dressmakers tape measure to monitor the mast rake and backstay length as it appears what is recommended by the manufacturer is a very good setting. I've also sourced recommended settings for the B, C and D rigs.

I'd like to have good settings on my boat that I only occasionally need to check. Like you I prefer to sail the boat rather than always be fiddling with it.

Cheers!

First Sail in the DF 95


Hi All

Took my DF 95 for a sail for the first time ever yesterday. Turned it on, put it into the water, started sailing. I started in a race about 5 minutes later and raced for the rest of the day until worsening weather (rain and hail squalls) sent everyone either home or to the nearby coffee shop.

First impressions:

1. If you use the stock rig and the exact settings recommended in the assembly instructions, the boat is pretty perfectly tuned from the word go. The only things you need to play with are the leech twist (especially on the jib) and the foot tension. (Note that altering the leech twist raises or lowers the booms so you do have to re-adjust the sheets to regain the recommended close-hauled sheeting settings.)

2. You should make sure that the jib boom balance weight is firmly glued into the boom end (not just gluing the threaded end on as per the instruction). I had mine pulled out and lost after a collision and entanglement. Most skippers have glued the weight in place so that its nearest end was 5mm out from the boom end

3. It helps to check all the settings regularly on a new boat or with new rigs as the rigging line will stretch as it settles in. Even small changes in settings can have a noticeable effect on performance.

4. Set up the mainsheet bridle (including the extra line to the keel bolt) so that the ring sits as close as possible to the sheeting point on the main boom in the close hauled position. This maximises sail winch efficiency (and probably prolongs winch life).

5. This is one of the sweetest model yachts I've ever sailed. It's surprisingly maneuverable for such a long narrow craft and certainly accelerates impressively when handled properly in the puffs. Its relatively stubby "A" rig has a huge wind range.

Cheers!

Karl
