Argh - the old 2oz chopped strand mat and isothalic polyester resin - hand laid and choppered - labour intensive, sure! overly wet layup, you bet! a bit more costly (back in the days when cost wasn't the driving force)5/8" marine ply sandwiched load areas, boatbuilding at its zenith! But hey - no ossie even 30 years on! Who knows how long they will last?
Good one Reggie. |

That is great information on the E30s' Colin. I'm looking forward to meeting and discussing their construction with you and Reg at the October Regatta. I believe that we will be still sailing the Hagar when a lot of the Mum 30's etc have disappeared. Our refurbishment program will be neverending, however the new rig now means that we can go out and enjoy her without any doubts about the rig. We will be testing the sails and have the sailmaker out on her this winter and she is penciled in to go up on a hard stand in June / July and I hope to rip off all the old layers of antifouling, remove the redundent underwater instuments, re-install the baffles over the rudder as well as cut and polish the top sides. We will take time in deciding on any changes to the downstairs layout.
Colin, I would like to hear anything about the dates when the E30s' were built? Mark 1 vs the mark 2's etc. |

Last weekend there was no work conducted on the New Hagar. Rod took out his son & mates for Micheals birthday & they stayed out on saturday night. Rod reported that they had to go back to the mooring due to the plough anchor not holding. They had a good comfortable night, however our selection of the bunk beding was reported as being too hard. They got the mainsail up only & mainly motored as it was a bit gusty.
On Sunday night I picked up the timberwork again for more varnish & this Saturday the sparky returns to finish off the internal lights etc. The stove is not working and needs to be re-installed when fixed. Should be out on the water this weekend at some stage. Chris |

Keep up the good work Chris and Co!
On another note, we took "Caroline" up from our berth at Sandy Bay just up the river to Geilston Bay (in Hobart) this morning and found the "other E30" that resides down here. "Zero Balance" looked neat and we could sure see heaps of differences between her (Mk1 with wheel steering) and "Caroline" (Mk2 with tiller). Almost would not see a simularity unless we knew to look hard. Got a tip on where to find the owner, so will try to catch him. |

Good morning Leigh, "Zero Balance" is owned by Ian Marshall who also contributes to the Forum. I will email a contact to you. Ian & his wife are planning to come up for the October weekend. Some of the photos we have of "Zero Balance" really look good. (Previously called "Bee Jay")

Leigh,
Forgot to mention earlier that during the October Regatta we will be away from Home ourselves & be sleeping where we fall down, ie, aboard the Hagar. I feel sure that between the Splinter & Hagar there would be enough bunks for you & co if you need a bunk. However we give you warning that there are at least three good snoorers aboard the Hagar! We are going to hoist some sails tomorrow!!! Chris |

Gee Chris, you reckon you snoor, Maree reckon that I tear the paint off the walls. I don't understand as I never hear it.
Could be a great raft up!, just bring your ear plugs after a few beers.
Talk about the raft up, I have just put in a new CD & PM3 player in. Hey "Splinter" is just a big Jute Box now but with only '70 & '80 music. Lets enjoy.
cheers, |

| This afternoon Ian & I went out for a short sail from North Harbour into the Sound & down to the entrance of Middle Harbour & back home again. It was a very light & patchy northeasterly breeze. We had the new main & the number four headsail on. The rest of the headsails are under Rods' house & Ian will pick them up tomorrow. The number four is a yankee style header and would not sheet properly untill we raised her up. She is small & flat and will be good in the heavy stuff. The main is quite full & fully batterned. The boat felt good and moved with ease and with a light and neutral helm. Will be looking for more pressure & bigger headsails tomorrow. Chris. |

Sounds like all is going well. I originally had a #3 & #4 Yankee cut. I only have the #4 left although I must admit I have only had it up to pass Safety for Cat 3 races. I just hold it back as a heavy weather jib. The '30 will sail under all Headsails with little or no weather helm. I am waiting for the report on Sunday night after you through up the #1 and kites. You are going to have a ball.
I spent yesterday servicing my engine changing all filters, new oil & belts. Had a major spill of diesel so back to the boat today to finish cleaning up. (Hate that diesel smell) Will have to bring the cushons home to air them out. I was amazed to find how much crudd was in the filters, I will be changing them more often now.
I am having a minor problem with my anti-fouling as I am only 8 months since the last slipping and it's bottom is shocking. Will follow it up under the maintance forum.
Enjoy a magnificent day in Sydney.

Well this afternoon, Sunday, Ian, Andy & Sally, Andys' wife & I went out for a sail at around 2.30pm. Ian bought down the No1 & 2 headies, but alas no kites. It was a steady little South Easter at around 10 to 12 knots. We went into the sound and out through the heads for about four or five miles to sea. The further out we went the stronger the breese was. It was up to 15 in some gusts. We had on the number 2 & the new mainsail. The main looks to be too full & was overpowering us & stalling us in the gusts & we cound not flatten it out enough. The mainsails cuningham is underpowered with the sail too long on the luff & almost scrapes the coachouse. Apart from that, the boat tracked really well upwind with just a little bit of weather helm. She is very high & dry with only the odd bit of spray on the fordeck. Downwind she was easy with no cavitation, even with me try to catch waves. We went home please with our first real sail.

Kevin when you next antifoul mix 100grams of the hottest chili pepper you can find (to 4 litres)Getting Zero Balance out for a clean up next week will try chili.the new main going very well,at 15knts very little weather helm.Got a win by 1 second.See you all in October.
Leigh heard you were in Geilston Bay will catch up with you soon.

Kevin,
What is on your agenda this weekend? Are you going outside whale watching or whatever?
Have not spoken the the boys yet. Still to contact the sparky to finish off the internal lights. We will be definatly be out on the Hagar over the weekend.

Good Afternoon Chris and all Endeavourers',
Would like to welcome another new Endeavourer, Greg Lacey who in his wisdom has purchased a '30 - "Magic Dragon" I hope he will join the forum. I suppose his handle would have to be "Puff".
This weekend I will be fiddling with "Splinter", and on Sunday going whale watching with the Port Hacking Cruising Group. I think about 15 - 20 Yachts
If anybody is interested here is the link
http://www.rmyc-porthacking.com.au/hello.trim/Coming%20Events.htm
and if anybody is interested, our Cruising Master John Barter, another ex Endeavour owner is preparing a Cruising Guide to Port Hacking.
http://www.rmyc-porthacking.com.au/hello.trim/Trim.htm
Chris, we will be leaving Gunnamatta Bay 11.0a.m., returning and anchoring up inside the Merries for lunch. I think I will stay on the boat Sunday night and see if I can catch a few bream. Then go for a sail on Monday.
Could have some great photos if we are lucky.
Enjoy the weekend all, the weather appears to be good.
cheers,

Well this afternoon Ian, myself & a friend went out for a cruise in the Hagar. Tested both of the original kites. They are both in good condition & have no marks, tears etc. The smaller is orange & with a black diamond, is flat and stands up really well & looks like a good kite for heavier weather. The big one is dark blue & red and is almost new, stood up well but could have larger shoulders & be a bit longer. Will have the sailmaker look at the boat & may order a larger number one. I do not care what women say, big is better! The Hagar slipped through the water really well in a light southeaster & downwind was as light as & tracked straight. You could leave the tiller & there was practically no weather or lee helm. Will take out the family tomorrow.

Chris,
Good to hear you got out for a sail on "Hagar" - sounds like she tracks as well as "Caroline" does. Keep up the good work

Sunday saw the Hagar out again, with SWMBObeyed, another couple & their two teenage kids. My kids have not been out yet, they think their dad is a bit of a pirate. It clouded over & was a light noreater. We went full main & No1 jib. We drove straight out to sea in an attempt to go whale spotting. We would have been about two mile from the hive of whale watching craft & the women began complaining about the cold & the sea. It was reasonably calm! Anyway we did not get to see the whales.
Our rig is somewhat slack. Does anyone have an idear of what tensions should be in the rig? ie, shrouds, inner stays, forestay & backstay? Should the mast be raked or straight up? & should it have bend or be straight in column?

Rigging foe E30
Chris from what i have found out so far a masthead rig like ours should have a 250mm rake aft with 50mm bend.I have the inner forstay fairly tight.When you get the rake right then play with the shrouds.

Re Riggs. This is greeat as I have been asking the same question for 4 years, but without another '30 to compare it against I have been flying blind. My mast is almost vertical or could have about 50mm of rake under pressure via the back stay.
Mast bend is fully adjustable and I can pull as much as we require. With my #1 & #2 they are reasonably full so we have about 100mm sag (or bend) in the forestay. As the breeze increases I apply more backstay and flatten both the Headsail & Main. The main is flatten mainly by the Inner forestay and the outhaul. I must admit I only put in inner forestay on at about 15 knots & building. #3 Blade comes in at about 18 knots.
Would like to hear from other '30's if they have tried various rakes and set ups.! I think October weekend will by very constructive for all as we all must have different set ups.
Would love to find somebody to tune the rig as mine is a sort of self taught, trial & error.
The one point of sailing that I feel we need to look at is when we crack to sheets and start to reach. Would that have anything to do with the rack in the mast?
cheers, |

The way that mast rake was explained to us in the yachtmaster course (and it may be wrong, but I believe I recall it enough to repeat the gist, even through this damned flu) is as follows.
Air flowing across a wing surface will always try to split, the majority will look for the quickest exit, while the remainder is drawn to the tip of the wing or foil, in the case of yachts this is the top of the sail.
Near the bottom of the sail, where curvature is greatest a good way from the leech, most of the air pressure flowing along the OUTER surface of the sail has time to smoothly release before reaching the leech and causing a vortex.
But the same width also allows more air to be redirected towards the top of the sail and flow at cross purposes to the driving wind (shown in lifting tell-tales). (This is only relevant where coanda effect, what makes wings work, is the principle driving force. None of this is relevant to the time that the sail is acting as a bag of wind and the boat is running)
Aircraft sometimes deal with this crossflow by having small vertical winglets on the ends of wingtips to break up this flow and redirect it backwards to reduce the drag of the vortex that forms just behind the wingtip if this flow is not controlled.
Some sailboats do it by raking the mast back and rendering the top part of the sail more effecient.
The direct air that hits the top of the sail has very little wing area to blow across, worse still, the release area is not clean as the leech is at its most pronounced angle in this part of the sail. So a vortex on the upper part of the sail is already likely even without the added factor of crossflow running vertically up the sail. Often the resulting sil flutter in the top of the leech is corrected by tightening the leech line, but sometimes this ignores the problem and merely makes a cosmetic correction.
Raking the mast back helps to make the leech at the very top of the sail more vertical, providing a cleaner release for direct air flow. This flow being stronger in turn better fights against the crossflow coming up the sail and better redirects it to flow off the leech instead of the tip. Thus it adds a very small fraction to accelerating the boat, but can add significantly to reducing the drag of having a vortex disturbing air at the leech of your upper mainsail.
As with all things, applications are limited. In the same way that some aircraft have swing-wings that can allow for a range of conditions by pivoting their attack and release angles, raking the mast lets you have a potential tool to maximise peformance in a limited band of conditions, leaving the mast raked out of columb as a standard will just slow you down most of the time.
Raking the mast is really only an issue in beating and close reaching, and even then sea state and duration of run need to be taken into account. For instance it makes no sense in a short course race.
Signs that it might be of benefit to consider trying mast rake are the top tell-tales on the main pointing up with no way of bringing them to level without depowering in some way (cunningham, outhaul and such), if the upper quarter of the mainsail leech has a consistent flutter in it, and the lower tell-tales are pointing somewhat upwards.
Finally, a vortex in the top of the main occassionaly manifests as lee-helm pressure. This is very design specific and seems to be an artefact of foil and bulb keel designs.
I think that is the sum total of what I am meant to remember.

Oh yes...for truly odd designs with mast rake...there is always this craft:

It is from a site on which the designer bemoans why this consept didn't take off and become the standard for oceon-going cats.
