ADDITIONAL HEADS Proposed by the Master-Shipwrights of England, in order to amend Two Ancient Charters, dated Anno 1605. and Anno 1612. who, the better to accommodate Navigation, and for the safety of Shipping in general, were Incorporated one entire Company, with Power to practise their Art and Mystery in all Rivers, Ports, Harbours, and Roads of England and Wales.  
I. THAT the Master-Builders, Master-Yard-keepers, and other Master-Ship-wrights of England and Wales, may( all and every of them) pay an equal and proportionable Contribution of tonnage and Poundage, agreeable to their Stations, and the burden of the Ships and Vessels they Build and Repair( saving Their Majesties Men of War, which is humbly submitted to such Proportion, and to be paid in such manner as may be thought reasonable,) towards the support of the Company of Shipwrights of England, according to the first intent of Incorporating them, for the well breeding of able and skilful Workmen in that Art and Mystery, and to maintain their poor disabled Cripples, and superannuated decayed Members.  
II. That wheresoever the Master-Builders, or Master-Shipwrights of England make Yards for the increase and conveniency of Navigation, and to encourage Trade, they may have and enjoy their Ways or Graving Grounds before their Yards( as well as those in present being) and to lay before, Pass, and Float into, and out of all and every their respective Yards, all sorts of Timber-Plank, and fir for Masts and Yards, with other Materials: Provided, they be not detrimental to the River of Thames, or to any other River, Port or Harbour of England or Wales, with submission to the Lord High Admiral of England to be judge of it, in case disputes shall arise.  
III. That the Members of the said Company, for the conveniency and safety of Navigation, may be admitted to practise their Trade in all Rivers, Ports, Harbours, and Roads of England and Wales, as their Charters time out of mind, have directed: And, That the Certificate of the Masters and Owners of Ships, using the Trade of the River Tine, of Decemb. 1684. touching the intolerable practise of Shipwrights of Newcastle, may be considered.  
IV. That Apprentices Indentures, when Enrolled by the Shipwrights of England, or their Deputies in the Out-Ports,( agreeable to their former Charters) may be good to all intents and purposes. The Stat. 5. Q. Eliz. Cap. 5. among other Trades, expressly names the Indentures of Shipwrights Apprentices, to be Enrolled in a Town Corporate; and the Custom of Cities and Corporation Towns, for private Inland Trades, are to the contrary.  
V. That the Order of Council, of the 27th of March, 1638. and the same again renewed the 18th of March, 1684/ 5 against the Interest of the said Company, may with all submission be considered.  
VI. That the Members of the said Company may be Protected at their Trades, and not liable to be impressed by common Press-Masters, to Serve as Seamen; but that a sufficient number of able Workmen, as their Majesties Navy and Yard service requires, may from time to time be supplied by the said Company, and their Deputies in the Out-Ports.  
VII. That there be a Clause to empower the Members of the said Company, to observe and keep the hours of beginning to Work at Six a Clock in the Morning, and to depart from Work at Six a Clock at Night, as is, and hath been the usual Custom, with allowance of time for a Breakfast and Dinner, agreeable to the Season of the Year.  
And, Whereas Their Majesties Royal Ancestors have given and granted to the said Company, and their Successors for ever, and to their Deputies in the Out-Ports( thereunto Deputed under their common Seal) full Power and Authority to Survey the Building and Repairing of all Ships and Vessels of England and Wales; and all manner of Timber and Plank, and other Materials prepared for the same; and to Inspect into the Workmanship, and remove all Sappy and Red-Wood, and see that they be substantially Built, with two Orlops at convenient distance, strong to carry Ordnance aloft, and allow with a Fore-Castle close for Fight: And have also given and granted unto the said Company, and to their Deputies in the Out-Ports, and their Successors for ever, full Power and Authority to admeasure all Ships and other Vessels of England and Wales, and, as occasion requires, from time to time to lay them a ground; and, according to an exact Admeasurement of their length, breadth, depth, and draft of Water, so to Rate and set down their burden of Tons, and to certify the same under their Hands, and the common Seal of the said Corporation.  
VIII. Now, to the end Surveys may be rendered more useful, and that Admeasurement be computed nearer the Truth, the Particulars following are proposed to be agreed upon, and settled by such By-Laws or General-Rules as the said Company shall appoint and order to be observed throughout England and Wales, and to inquire into the same at Surveys.  

Particular  
1. In Timbring of a Ship or Vessel, there be a general Rule, That the Floor-Timbers, the Futtocks, and Top-Timbers have a serviceable and sufficient Scarf to each other, with regard to the proportion of their Scantlings.  
2. In Planking a Ship or Vessel there be a general Rule, That the Planks from Butt to Butt, have a serviceable and sufficient Scarf to each other, with regard to the burden and length of the Ship or Vessel, and the substance and length of the Planks.  
3. A general Rule, That the Treenails, from the Keel to the second Plank, above the second Streek of Wales, Inclusive, be of seasoned young English Oak, fit for service under Water, and of a proportionable size to their length, agreeable to the burden of the Ship or Vessel; and that they Inspect into the well placing of them, with regard to the Timber and Plank they are to fasten and secure.  
4. A general Rule, That the Bolts, and other Iron-work, be of a proportionable size to their length, agreeable to the burden of the Ship or Vessel; and that they inspect into the well-placing of them, with regard to the Timber and Plank, and part of the Ship or Vessel they are to fasten and secure.  
5. A general Rule, That a proportionable number of threads of Hair, and of white and black Oakham, be appointed to be well driven and bottomed in the Seams, with regard to the thickness of the Plank.   
IX. And, Whereas there are great abuses committed by the ill Hewing of Timber; It is therefore necessary a general Rule be observed, That all Timber, when squared, may be so Hewed, that the Flat do contain both the Waynes( and not less): And, That in converting of Timber into Plank, it be full Cut, and hold out, according to its proper denomination in Inches and parts of an Inch, and to be Admeasured between the Waynes on the Wayney-side, and half the wain allowed in Admeasurement, according to the usual Custom.  
X. And, inasmuch as Surveys are of necessary and absolute use, for the preservation of the lives of Their Majesties Subjects, and the security of Merchants Goods from damage, which often happens to the loss of Mariners Wages, and Their Majesties Customs: And, for that the Master-Builders, and other Skilful Master Shipwrights of England, are often called and summoned to attend on them, and do spend much of their time therein, both a float and a shore; therefore it is thought reasonable, That when the Master, Owners, or Freighters require to have a Ship or Vessel Surveyed, they may then be liable to pay one Penny per Ton for the said Survey: And to prevent unnecessary Disputes, vexatious Actions and Suits at Law, in case of damnified Goods, or the Foundering of a Ship or Vessel; it is expedient, That the Masters of Ships, &c. have a Certificate from the said Company, to vouch for themselves and their Owners, that their Ships or Vessels have, by able and skilful Persons, been well Surveyed and Repaired, agreeable to the Rules and Ordinances of the Company of Shipwrights of England, and that they are fit for the Sea, and to receive in Merchants Goods for such a— Voyage.  
XI. That the said Company of Shipwrights of England, be required once a Year, or as often as may be thought fit, to present Their Majesties with a Scheme, or List of the Names of Ships, &c. the time when Launched, and Place where Built, the Master Builders Names, and Numbers of Shipwrights and Apprentices in the Ports of England and Wales, and also the Names of the Ships and Vessels that are Cast, and to be broken up.  
XII. On behalf of the said Company, it is most humbly prayed, That in the Amendment of the aforesaid Charter, there be a Clause for a small piece of wast Ground( in Their Majesties Gift) in some convenient Place near the River of Thames; and the like in the Rivers of S●vern, Medway, and Tine, in order for Alms-Houses to be Erected, that the Shipwrights of England may see the Relief and Maintenance of their poor disabled Cripples and superannuated Members.  
And it is further humbly Prayed, That the said Company may be admitted to amend or add such other Heads or Clauses as may appear to be of Service and Reasonable.
