After yesterdays race at North Harbour we returned to the mooring and undertook a few small jobs on the Hagar. Firstly, Rod had procured a new toy, a guage for measuring rig tension. We found that the port & starboard shroud and baby stays are the same and that when we tweek up the rig using the back stay and baby stay tensioners both sets of stays adjust equally. This was a bit of a revelation as we assumed that something must be out of sinc. This is due to the great differences in boat speed which show on our instruments when racing to windward. Yesterday we got her up to 6.2 knots of the port tack but could not do any better that about 5.6 knots on the starboard tack. So its back to the drawing board. The rig looks upright, having taking a good look last weekend while tied up alongside the marina.
Oh, yes, and I can vouch for the strength of the aft deck tie fittings? I forgot to east the tie line aft and we snapped one of the marinas lines as the tide dropped.
We will next be looking at the instruments which continue to play-up and are not reading the wind speed and direction correctly. This could be related to our boat speed or just the log position in the hull. The mast level looked OK last week & when we had her up on the slips in August the log appeared to be centred correctly.
The second problem is with the wind direction needle which is swinging around and is accurate upwind about 50% of the time and does not read off the breeze. These two problems may both be an electrical fault or bad connection.

Hi Chris,
I guess your speed transducer is not lined up correctly. Average the two readings and thats probably the speed you were doing. I believe the GPS gives more meaningful readings. Its certainly free of underwater effects.

| If your wind instrument is linked into your log so it can display in true wind as well as apparent wind, an error on the log (ie; gunk in the speed transducer under the boat or simular) can cause an error if you are looking at true breeze. Not sure if this explains all of the issue with the wind instrument you mention though. |

Adrian,
In reply to your solution, the answer is that we have already tested the boat speed with Rods' GPS instrument and the results were that we are slower on Starbord and quicker on the Port side tack. We also remove the log after each days racing and it has only been clogged with weed once and it was noticeable at once.
One of the old chums in our club said that it was most likely the jib sheeting positions and we may have them sheeted at different angles.
We will keep looking. It would be nice to have her going at 6.2 knots on both tacks.

Hi Chris,
After posting the last note I thought of someting else. It is posible that the direction of the waves can cause similar variations in speed. On one tack the yacht might be moving more into the waves than on the other tack. This is particularly evident when you get a lift on one tack. As a result you travel much faster on one tack than the other.

No Adrian, the Hagar is consistent in most sea and non-sea conditions, in that the boat is always quicker on the port tack and slower on the starboard tack. However I'll get Rod to take out his GPS instrument next weekend and give it another test.
Our three electronic read-out instruments are all integrated and we suspect that there is a fault in the system but this has nothing to do with the port and starboard boat speed problem.
The instruments are old Navman Instruments labelled Horizon with three dials which from left to right being:
1. The depth,
2. The speed across the water as well as apparent &
3. The wind speed & direction.

Chris,
Could I be so bold as to suggest that during the tests you did that Rod was helming when you were on the port tack and you on the starboard?
I am surprised Eric H did not suggest this! |

Please explain??
Leigh, for what reason do you suggest that we test sail with Rod on the one tack & myself on the other?

| Only a joke Chris - port was the faster tack, just thought Rod may have been steering on that one! |

No Leigh,
The Hagar will always go quicker when I'm steering, naturally! Rod is a member of the "federated forward hands union". And I'm most dedicated blunt end person. Tactics & steering are my go. However Rod has come a long way since taking to the helm of Endeavours, he has also mastered navigation and done a number of Sydney to Hobarts as well as having won three E26 nationals on the trot and beaten all the fancy freebooters from North & South. Not bad for a forward hand!
Anyway, if you have any sugestions regarding our electronic and speed problems please give your suggestions.

Eric,
You never disappoint us and it is that time of the year so feel free to let it all out and give those sneaky southerns a touch up with your charming wit.
Have you got the new carbon stick in yet?

This weekend will see the Hagar racing in the Friday night twilighter at Manly and on Saturday morning we are booking into the work berth at the local marina to finish off a lot of timber work. This includes the head timber edgeing, a teak step for the WC, a teak step to go over the entrance to the companionway as well as a teak plague for attaching the emergency knife & tools. Rod has some other bits to do as well, while I'm the timber man.
We will be again racing Sunday in the North Harbour Islands Race which takes us up to Drummoyne and back.

This afternoon Rod & myself went down to the Davis marina and for about the fourth time found that they had double booked the work berth with the old Eos enjoying her fiftith birthday. We did a deal with the other boat owner and took his marina birth and worked on the Hagar for the afternoon.
Rod bogged up all the cavities about the new SS gunnel fittings as well as filling some other old gaps in the gunnels. I cut out a new foot tread in teak for the entrance to the hatch. We glued and screwed it down and cleaned it up. I then cut out a teak plate for the emergency knife and deck tools as well as measuring up and cutting out a new teak step for the WC. Not all completed but we got a lot done in the time allowed. Racing at North Harbour tomorrow.

The past weekend saw us only sailing on Friday night with no race at North Harbour on Sunday. Rod went down to the Hagar on Sunday afternoon and tightened up the shrouds and lowers, having tightened the forestay on Friday. This should help to power her up as we suspect that the rig has slackened off with the heavier breezes as well as us pulling hard on the backstay when we race.
Rod also installed some new timber work for the emergency knife & tools.
Also pleasing is the clean bilge following the tightening of the engine sump nut & with a new soft washer. The boat hardly leaks at all with only some rainwater getting in around the chain plates. The starboard side plate is still to be replaced.
We will be racing next Friday as well as again at North Harbour on Sunday.

Rod rang me this evening from up the coast somewhere on work related adventures with the news that he has at last contacted a former E30 yacht racing campaigner who raced his boat extensively offshore in past years. I will get all the good stuff off Rod when he gets home on the weekend. He tells me that this boat had 2000 lbs added to her which Rod described "to stiffen her up", as well as increased sail area for better performance. He used an old number one kite off the eighteen footer KB. Can you remember back that far? The contact will be faxing down the IOR rating which will give us the sail areas as well as other dimensions.
All good stuff to know and perhaps make us go quicker. The contact also said that he was as quick & quicker than the E26's downwind?

Chris,
I have sailed on a few different few half tonners over the years, including cat 1 and 2 offshore races. In comparison to those racing boats, our Endeavour 30 MkII was already quite stiff and heavier. Not sure about needing the extra 2000lbs mentioned above.
My present boat just has the standard Northshore 38 keel and a fractional spinnaker - she appears to run as quickly as her sisterships with the deeper lead shoe keel (600kg) even when they fly a masthead kite. Would have thought the extra weight in the boat you mention would have made her slower downwind, but the more righting moment should be an advantage upwind in a heavier blow though. A real matter for tradeoff on what the "normal" conditions you race in are. |

Hi Leigh,
I agree with you about the extra wight in the boat and I would not be keen about adding anything to slow the Hagar down off the wind as she is slow enough now! We need a bigger fuller shouldered kite of the same shape as the number ones used in the E26' and with our extra six odd feet of mast height it would certainly help us.
However this is the second time that I've heard of extra weight being added. The owner of the Mk2 E30, Santana up at Lake Macquarie reported removing a heap of lead ingots from his oily bilges when he was cleaning her up.
The argument is that the extra weight increases the boats righting moment and as our boats perform better on the wind this argument can be justified especially if you are beating into the Bass Strait.
