Mainsail boom

Introducing the mainsail boom, whittled from an old rotting mast.  I've also changed the sheeting arrangements, moving away from the traditional Drascombe 'W' pattern to a straightforward double block arrangement.

Having previously enjoyed both making and sailing with a mizzen boom, I had no real intention of moving on to the mainsail.  The decision to proceed was based, in part, on some very useful descriptions posted on the Drascombe Association Forum regarding methodology.  Additionally, it helped that I had an old mast which was waiting to be whittled into shape.  Lastly, there's nothing like a summer holiday for proceeding with a project.
The decision was not based on any real expectation of an improvement in sailing performance.  Daisy II already sailed perfectly well and I knew of no conclusive proof that a boom improves things other than heresay.  There are no doubts that a boom prevents the sail from collapsing in downwind situations.  Moreover, there was a realisation that the boom would change the way the boat performed and discovering exactly how was certainly a lure.

Boom length 310cm.  I planed an old, rotting coaster mast to a diameter of roughly 5.5cm.  This, handily, already had a slot for the intended outhaul, although it would be necessary to create a smaller wheel for this.

The wheel was created from an old wooden kitchen chopping board; the initial disc was cut from the wood and then centred on a screw bit mounting for a Dremel which, when rotating, enabled various sanding jobs to be done, including the concave groove on its diameter.

At the other end, a set of jaws, hewn from pine, were shaped, sanded and then glued to the main shaft.  Finally, I cut a curve to match the diameter of the mast against which the boom will rest.

Not photographed are the leather protectors glued to each end of the boom.

Rigging decisions involving sheeting, outhaul, topping lift and attachment to the mast can be observed from the following pictures of today's maiden sail.

I took the opportunity to change the sheeting arrangements.  The traditional Drascombe 'W' arrangement has been replaced with a simple pair of double blocks, one on the clew and the other, with becket, on the slider.  The latter was purchased and, although slightly oversized, is very effective.  The improvement in performance is manifest.  Sheeting in is much less effort and, when paying out during gusts, the sheet slides through with ease.  A fantastic and unexpected bonus from this modification.

Following advice on the Drascombe forum, the block attaches to the boom by means of a sliding strap which I made from an old trailer winching strop.  The idea is that the strap slides along the boom to match the foot of the sail depending on how it is reefed.  This worked well enough.  Initially, I had the clew outhaul passing through a loop in this strap, but I may dispense with this and have  the strap running free inside the outhaul.

The clew outhaul passes through the slot in the end of the boom and then along the boom to a clamcleat positioned halfway along the boom.  This will enable easy tensioning of the foot.  At the tack-end, the jaws are held against the mast by luff tension and the tack downhaul.  A pair of stainless steel eyes from an eyebolt and an eye nut above and below the jaws enable these attachments.

Another view of the sliding strap and clew outhaul.

The boom also provides a great place from which to hang various plastic bags which hopefully help to deter wildlife whilst on the mooring.

Fitting the boom was made more challenging due to several passing showers.

Once fitted, the rain showers seemed to stop and the reward was a pleasant 'maiden' sail up the Orwell, during which time lugger Truant was having a splendid sail.

The maiden sail for the boom involved full main and a few rolls in the jib.  Winds were F3-5 and the boat heeled over nicely during the gusts, and the new sheeting arrangements for the main worked exceptionally well.  She certainly feels different to sail, the mainsheet is more comfortable to hold and the sail feels more controlled.  The downside is the obvious boom swinging just above head height in the cockpit area, although in time one supposes this will be an extra thing to grab hold of when moving around the boat.

Still thinking about the cruise

The latest upshot of last week's cruise is this video which gave me the perfect excuse to learn how to fiddle with iMovie software.

Yesterday, I popped down for a brief sail.  In truth, the purpose had been to play with a new boom, but that will have to wait until a delivery of various fittings is received.  That will be the subject of another post...  The other reason for going yesterday was that it was the only day spared from various summer storms which seem to be making tracks across the UK....ever more thankful that the cruise took place last week and not this.

The other good news is that the latest 'anti-seagull' device seems to be working well and no further mess has been left on the boat.

Summer Cruise, July 28th to August 4th 2014

Coaster Valentine sailing NW along the Blackwater from Osea Island

Participants: Drascombe Coasters Daisy II and Valentine.
Identified, active Drascombes encountered along the way: Longboat Cruiser Pen; Dabber Susie

This has been the most ambitious and, ultimately, most rewarding cruise undertaken in Daisy II to date.  A track log of 204.3 nautical miles speaks for itself.  In partnership with coaster Valentine, the voyage covered six estuaries/rivers (Daisy II covering a seventh - the Deben - after Valentine shortened her trip by a day returning directly to the Orwell from the Crouch), undertook three lengthy sea passages and, but for one night on a mooring in West Mersea and my final night at Woodbridge, enjoyed the spectacular freedom of spending all remaining nights at anchor.

The only minor blot came afterwards, when downloading track data and realising that we had travelled too far for the memory of my previously trusty Garmin GPS, which dutifully deleted the tracks from the first six days in recording the seventh.  Having realised something was up, I recorded my final, eighth day on a Motion-X GPS App for the iPhone.  Hence, I've had to draw the rough outline of the first six day's cruises on the map below.

All but the white and blue tracks are 'best guesses' plotted onto the map after the GPS deleted the real tracks

The final two days - in white and blue - are genuine, the remainder are best guesses and, naturally, miss out the many passages where we were beating into wind, such as north from Colne Point to Mersea Stone Point and a particularly arduous stretch south west into the Crouch after having previously passed through the Rays'n Channel.

Monday 28 July
Left mooring at 2pm, sailed upstream briefly for rendezvous with coaster Valentine.  Sailed downstream and then up the Stour for evening anchorage off Harkstead Point.

Tuesday 29 July 
Left anchorage early, taking remaining ebb out through Harwich harbour, on to past the Naze Tower, and joining the new flood tide down The Wallet.  We turned into the wind past Colne Point, beating along to lunchtime beaching and afternoon anchorage at Mersea Stone.  Later in the afternoon, motor/sailed up Brightlingsea Creek, and then tied up to public pontoon.  Early evening sail along the Pyefleet Channel to evening anchorage adjacent to Maydays Marsh.

Wednesday 30 July
Returned to the Colne, past Mersea Stone and then SW down the River Blackwater.  Late morning beaching at Osea Island.  Lunchtime encounter with LBC Pen (which is based at Marconi SC) off Osea, then sailing in dwindling winds up towards Heybridge.  Returning with the ebb past Osea and on to West Mersea for evening meal in West Mersea Yacht Club, and then borrowing one of their moorings for the night.

Thursday 31 July
Left West Mersea, after briefly calling in once more at West Mersea to deal with Valentine rudder stock issue.  Sailed around St Peter's Flats, then south through the Rays'n, finally beating SW into the River Crouch. past the Inner Crouch buoy.  Then, dropped sail and motored up to public pontoon at Burnham-on-Crouch for early evening meal.  Finally returned down Crouch, into River Roach, anchoring in Brankfleet.

At the cunningly named 'Brandy Hole Yacht Club'.  Contrary to information in the otherwise excellent Imray publication, East Coast Pilot, there is no official club pontoon.  We had to scramble ashore to gain permission to pull up here.

Saturday 2 August
Morning trip to Burnham, picking up crew and returning to River Roach, sailing up the Roach past Paglesham, where we had a rendezvous with Dabber Susie, and on to an area just beyond the entrance to Bartonhall Creek; returning for mid-afternoon snack at anchor.  Returned past Paglesham, into Devil's Reach and then south into Yokesfleet Creek, clockwise around Rushley Island, taking in the view of Havengore Bridge and Creek and the rough seas beyond.  Past Sutton's boatyard, returning down Yokesfleet, along the Roach, and then returning crew to Burnham for evening meal.  Return to Brankfleet for final anchorage.

Isn't the outboard sort of ..... cheating....?!

Prequel post - East Coast Cruise, 28th July to 4th August 2014

From the vantage point of The Anchor Inn, Woodbridge, it's clear that locals cannot quite believe that a Drascombe Coaster is capable of sailing, in a single day, the 39 nautical miles from the mouth of the River Roach to Tide Mill Quay towards the navigable head of the River Deben.  The photo is proof of the ending; the author's word will have to suffice regarding the veracity of the start.

We left the Roach at 5am in still conditions, but forewarned by an inshore waters forecast of S/SW F4-5, occasionally 6.  The outboard motor was deployed as far as the mouth of the River Crouch.  Thereafter, the simultaneous occurrence of morning wind and sunrise resulted in full sail being set.

The only major issue was a brief dalliance with the Buxey Sands as we approached the Swin spitway.  Otherwise, we proceeded without mishap until winds began to reflect the forecast off the Naze Tower.  My companion in his coaster Valentine was set for the Orwell.  I was bound for the Deben.  Between then and the Deben Bar, sail was systematically reduced, and it was with much relief that I entered the Deben with a scrap of jib and the help, once more, of an outboard for the final few miles.  Seas by this time were ridiculously heavy - F5 winds over tide.  

So, I sit here with no real right to have negotiated the final passage, and deeply grateful to the late John Watkinson for his genius in designing such wonderful boats.

The cruise report will be forthcoming as soon as I reach terra firma.  184 nautical miles to date.  So far, in fact, that the GPS had run out of memory and an iPhone app will have to do tomorrow in place of the usual means of recording tracks.  Let's hope it does its job as well as Daisy II does hers.
