to his breach, unless he can prove that the insurer, by his conduct, has waived his right to invoke the breach, possibility provided in section 34(3) of the Marine Insurance Act 1906 (MIA). Furthermore, in the absence of express warranties the MIA will imply them, notably a warranty to provide a seaworthy vessel at the commencement of the voyage in a voyage policy (section 39(1)) and a warranty of legality of the insured voyage (section 41). Salvage and prizes The term "salvage" refers to the practice of rendering aid to a vessel in distress. Apart from the consideration that the sea is traditionally "a place of safety", with sailors honour-bound to render assistance as required, it is obviously in underwriters' interests to encourage assistance to vessels in danger of being wrecked. A policy will usually include a "sue and labour" clause which will cover the reasonable costs incurred by a shipowner in his avoiding a greater loss. At sea, a ship in distress will typically agree to "Lloyd's Open Form" with any potential salvor. The Lloyd's Open Form (LOF) is the standard contract, although other forms exist. The Lloyd's Open Form is headed "No cure — no pay"; the intention being that if the attempted salvage is unsuccessful, no award will be made. However, this principle has been weakened in recent years, and awards are now permitted in cases where, although the ship might have sunk, pollution has been avoided or mitigated. In other circumstances the "salvor" may invoke the SCOPIC terms (most recent and commonly used rendition is SCOPIC 2000) in contrast to the LOF these terms mean that the salvor will be paid even if the salvage attempt is unsuccessful. The amount the salvor receives is limited to cover the costs of the salvage attempt and 25% above it. One of the main negative factors in invoking SCOPIC (on the salvor's behalf) is if the salvage attempt is successful the amount at which the salvor can claim under article 13 of LOF is discounted. The Lloyd's Open Form, once agreed, allows salvage attempts to begin immediately. The extent of any award is determined later; although the standard wording refers to the Chairman of Lloyd's arbitrating any award, in practice the role of arbitrator is passed to specialist admiralty QCs. A ship captured in war is referred to as a prize, and the captors entitled to prize money. Again,
