To add to alenka's comments, all of which I very much appreciate, I picked up an interesting tip while talking to the Z-Spar people at the Annapolis Boat Show this week: whenever you wash down the deck and fittings after an outing, just stick the hose into the mast above the furling mechanism to flush out the salt and grime. The Aerorig is not patented as its been used for years by model boat enthusiasts. The dished end is usually used at both ends of the pressure vessel and welded with the cylinder. Boats need stays if the mast partner is not sized and supported well enough to resist all the sideways forces generated by the sail rig. Yacht rigging is done with oversize wire ensuring long life and a safety factor which exceeds the designed safe working load. 2P where L p radius to which the head was formed, measured on the concave side of the head P p maximum allowable working pressure S p maximum allowable working stress, using values given in Table 1A of Section II, Part D t p minimum. The word drascombe is also used as a generic term for any boat built to a design by John Watkinson. It seems to me that a unstayed 55ft mast, even in carbon, will weigh over 100lbs?? Especially as unstayed masts, by their very nature, have to be heavier than stayed ones. Use of Pressure Thickness Charts for Flat Heads and Bolted Flat Cover Plates (Figs. Unstayed Meaning.

On small sailboats, masts may be "stepped" (put in place) with the bottom end in a receptacle that is supported above the keel of the boat or on the deck or other superstructure that allows the mast to be raised at a hinge point until it is erect. A major oil company revitalizing an Iraqi oil field called on Becht Engineering to review several hundred pressure vessels containing thinned regions to determine their fitness for service (FFS) per the API-579-1/ASME-FFS-1 Part 5 process for analyzing Local Thin Areas (LTAs). Setup to race or cruise, many newer sails, running rigging, and deck hardware. The advantage of having a flat bow and transom is more volume and carrying capacity for the length. However, an unstayed mast must be of significantly larger diameter to compensate for the lack of stays. The answer is a `cruising chute'. Why is a Carpenter's Pencil Flat? And Other.

In the estimates we did or my cruising boat the unstayed rig is lighter. To be picky and see what we can learn, there are some wrinkles in the head of the mainsail (the "head" in a 4 sided sail is the edge tied along the upper spar - the top corner is the "peak") and they are a sign of me being lazy - but a few are OK when the wind is light and you are trying to power up the boat.

The work reported in this paper was undertaken to make a comparative study on the effect of unstayed flat head pierced concentrically or eccentrically by using ASME Section VIII Division 1 and to study the stress pattern in both the cases using Finite Element Analysis (FEA) as a referral methodology. of holes of 19mm dia. In the 1970s while on his first circumnavigation, Nick needed to replace his original 28' yacht named Wylo. Durable, production-grade thermoplastic is heated in an extrusion head and deposited in thin layers on a modeling base. The minimum required thickness of flat unstayed circular heads, covers and blind flanges attached by bolts causing an edge moment in which case the thickness shall be calculated by the following formula: Where, C = a. Dished head subject to internal or external pressure: Minimum required dish thickness and maximum flange loads-B5: Unstayed and stayed flat ends and plates: Minimum required thickness-Welded circular end rectangular ends-Bolted circular end rectangular ends-Stayed flat cover-U-Tube tubesheet-Fixed tubesheet-Floating head tubesheet-B6. The purpose of this second edition is to update the example problems to keep current with the changes incorporated into the 2013 edition of the ASME B&PV Code, Section VIII, Division 1. 1 table OR as per ASME Sec I-PG-31 (unstayed flat head and cover).
