Women's Shipbuilding Day Brings out Talent and Enthusiasm, As Always
Maine’s First Ship Maine’s First Ship: Reconstructing the Fall 2019 Special points of interest: • Virginia’s sails under Women’s shipbuilding day brings out construction • “Beach Pea” peapod talent and enthusiasm, as always raffle supports launch • Caulking makes Virginia watertight • Spars and rigging • Traditional shallops dur- ing the Popham era • MFS volunteers sail on Portsmouth’s Gundalow • School groups visit MFS • Summer at Freight Shed series continues with lectures and hands-on events A sunny Sunday morning, following the wright Rob Stevens led plank, it was clamped into extra hour of sleep due the many hands in mark- place.

Standing rigging that supports a mast fore and aft. 1 The mast on a sailboat must either be strong enough to stand by itself under a full press of sail, or it must be supported by standing rigging. This section discusses shrouds, stays, and spreaders: the fundamental compo‑ nents of standing rigging, Figure 4–1. 2 A simple standing rigging, found on sailing dinghies, consists of two shrouds and a jibstay, Figure 4‑2. The ends of these supports typically have swaged terminals Jibstay Shrouds with an eye at the upper end and a turnbuckle stem at the Backstay Jibstay Upper Boom Shroud Crutch Lower Shrouds Figure 4–2 Simple Standing Rigging lower end. Swaging is a method of permanently attach‑ ing terminals to wire rope by deforming a steel sleeve to clamp it to a wire securely. The shrouds and stays are typically attached at the upper end to tangs that are a part of the mast, Figure 4‑3. The lower ends of the jibstay and shrouds connect to the stemhead fitting and shroud chain plates, respectively, through turnbuckles. Turnbuckles permit easy and precise adjustment of standing rigging, Figure 4–1 Standing Rigging Sail 28 4 – Standing Rigging Mast Ta ng Through Bolts Clevis Pin Swaged Fitting Shroud or Stay Cotter Pin Backstay Jibstay Figure 4–3 Shroud and Tang Assembly Shroud or Stay Swaged Fitting Right Hand Thread Tu rnbuckle Barrel Cotter Pins Left Hand Thread Marine Fork Clevis Pin Figure 4–5 Fractional Rig Sloop provide a better sail shape, is possible with a fractional Cotter Pin rig. -

Forestay tension Hints & Advice (H&A), (part. no: 595-540-E). The forestay tension is mainly controlled by tightness of the angled cap shrouds.

Rig Tuning Guidelines
RIG TUNING GUIDELINES Large books have been written on this subject, but we shall attempt to give you a concise set of basic guidelines. So here goes..... The aims of RIG TUNING are as follows: a. Ensure a straight mast athwartships b. Control sail shape. c. Achieve proper helm balance in a variety of conditions d. Spread loads appropriately on spars, rigging and boat. Different rig configurations require a different rig tuning process: --------------------------------------------------------------------- RIG TUNING - SINGLE SPREADER MASTHEAD RIG --------------------------------------------------------------------- 1. Fore and Aft Tune 1.1 Mast Rake Mast rake is determined by forestay length. Rake affects helm balance - raking the mast increases weather helm. As a starting point, use the designed rake on the sailplan (ask the boat designer, not the mastmaker). If no information is available, start at 1:30.(eg 50 cm rake on a 15m mast). To measure rake, tension the backstay approximately 60%, then check rake with a weight attached to the main halyard. (Boat must be floating level when you do this!). Adjust forestay as necessary to obtain the desired angle. 1.2 Mast Bend A certain amount of pre-set mast bend is desirable, to stabilise the middle part of the mast and thus minimise rig pump in a seaway. With a masthead rig, mast bend can be induced by tensioning the forward lowers (if fitted), or babystay (if fitted). See 2.2.3 below. 2. Transverse Tune 2.1 Centering the mast in the boat. Ensure backstay and upper shrouds are relatively slack (to minimise mast bend). Use the main halyard to measure from the masthead to the chainplate each side. -
