The contested valuation evidence
23Two witnesses gave evidence as to the value of the motorboat. They were Captain Kysil, qualified on behalf of Mr Anastasopoulos, and Mr Munroe, qualified on behalf of Mr Seymour, who was in the same interest as the appellants. Captain Kysil's evidence as to the value of the motorboat was admitted over objection. There was no objection to the admissibility of Mr Munroe's evidence. Each of the appellants submits that the primary judge erred in admitting the valuation evidence of Captain Kysil.
24Captain Kysil estimated the value of the motorboat and trailer in February 2009 at $180,000. That valuation did not take account of the existing damage. It did take account of the fact that the motorboat required further refurbishment to put it in good working order. Captain Kysil estimated the cost of that refurbishment at about $20,000. In his oral evidence, he estimated the cost of transporting a replacement vessel to Australia at $20,000 (Black 562) and estimated the cost of replacing the trailer at $15,000 (Black 562). That oral evidence was not objected to.
25Mr Munroe's opinion was that the value of the vessel in May 2010 was $25,000. That valuation also did not take account of the existing damage but did take account of the fact that, prior to the accident, the cost of bringing the vessel "to a working condition" would have been about $20,000. Mr Munroe arrived at the value of $25,000 by reference to the prices (in US dollars) for which two 1967 Donzi 28-foot motorboats were being offered for sale in the United States. He was unable to identify any pre-1990 Donzi vessels which had been sold or offered for sale in Australia. Mr Munroe took the average of those "expected sale prices" in the United States, converted it to Australian dollars, added a freight allowance of $10,000, deducted $20,000 as the estimated cost of bringing the vessel to good working condition, and rounded the number up to $25,000 by adding a "small allowance" ($3,129) for the value of the trailer.
26The principles governing the admissibility of expert evidence under the exception to the opinion rule in s 79(1) of the Evidence Act 1995 are summarised in Dasreef Pty Ltd v Hawchar [2011] HCA 21; 243 CLR 588. The discussion in the judgment of the plurality (French CJ, Gummow, Hayne, Crennan, Kiefel and Bell JJ) at [31]-[42] emphasises the following matters. First, when addressing the admissibility of expert opinion, it is necessary to identify the fact or facts in issue to which the opinion is said to be relevant in the sense required by s 55(1) of the Act. Secondly, it is necessary to identify the specialised knowledge on which the expert's opinion is wholly or substantially based. It must also be shown that the specialised knowledge is based on training, study or experience. Thirdly, ordinarily the evidence must explain how the relevant field of specialised knowledge in which the witness is expert and on which the opinion is based, has been applied to produce the opinion propounded. Finally, a failure to demonstrate that an opinion is wholly or substantially based on specialised knowledge, which in turn is based on the witness's training, study or experience goes to the admissibility of the evidence and not merely to its weight.
27Objection was taken to Captain Kysil's valuation evidence on two bases. First, it was said that he had no relevant specialised knowledge based on training, study or experience which qualified him to give opinion evidence as to the value of the motorboat. Secondly, it was said that his evidence did not clearly state the assumptions on which it was based or explain how his conclusion as to value was arrived at or demonstrate that it was based upon any specialised knowledge. The primary judge delivered reasons for admitting Captain Kysil's valuation evidence over those objections. Although a recording of those reasons appears to have been taken, no transcript was produced. As a result this Court must proceed on the basis that the primary judge addressed and rejected each of these objections to its admission.
28In this Court the appellants argue that each of these objections should have been upheld and the evidence rejected. Before addressing this argument and Captain Kysil's qualifications and evidence, it is necessary to explain a little further the issues concerning the motorboat and its value.
29The respondent's evidence, which the primary judge appears to have accepted (Reasons, 17 December 2010, p 7) was that he purchased the motorboat in 1996 or 1997 for $70,000 and replaced the engines in 2002 or 2003 at a cost of over $20,000 (Reasons, p 30). In his evidence in chief the respondent said that when sold to him the vessel was described as a Donzi 28-foot "off-shore" racer built in 1963 or 1964 which was of "historical value". However, when pressed in cross-examination, the respondent said that he could not recall how the boat was described to him when sold (Black 72-73). The respondent received no documents at that time which showed the provenance of the vessel or its date of manufacture or specification. The motorboat itself had no permanent hull or other identifier which established its date of manufacture, specification or correct description. There were admitted in evidence, over objection, printouts from a website which stated that the Donzi powerboat was first manufactured in Miami, Florida, in about 1964 and that there were off-shore racing specification versions of the motorboat produced as well as production versions. The admissibility of that evidence was not the subject of challenge on appeal.
30It was this evidence which caused the primary judge to record that there were "difficulties in establishing with certainty, in 2010, whether the first Donzi boat was made in 1963 or 1964 or 1965" (Reasons, pp 28-29). However, the primary judge went on to record (Reasons, p 29):
"... the thrust of the evidence both from [Mr Anastasopoulos] and from [his] expert Captain Kysil was to the effect that the first boats made by Donzi were off shore racing craft and [that this] boat is one of those boats."
Her Honour concluded that the motorboat was "rare" and likely to have the value attributed to it by Captain Kysil (Reasons, pp 29-30).
31Captain Kysil's evidence was relied upon to justify findings that the motorboat was an off-shore racer, as distinct from a production version of the Donzi 28 foot vessel, that it was manufactured in the mid-1960s, that it was for those reasons rare and that such a vessel had a value, in Australia, of $180,000.
32Captain Kysil produced four written reports. They were dated 21 February 2009, 23 June 2009, 20 February 2010 and 10 June 2010. The last report was in response to Mr Munroe's report dated 12 May 2010. The reports which contained opinions as to value were those dated 21 February 2009 and 10 June 2010. The latter repeated the opinion as to value stated in the former. The report dated 20 February 2010 attached a copy of Captain Kysil's curriculum vitae and the Expert Witness Code of Conduct.
33Paragraphs 30 and 31 of the first report and a concluding paragraph under the heading "Summary" set out Captain Kysil's evidence as to the value of the motorboat:
"30. Some research around the subject craft type indicates this significant early muscle boat classic example of the Donzie 28 may be very rare to find. Two 1967 examples of Donzie 28 muscle boats in the USA were found as comparitors. The subject craft may be one of the last remaining examples if not the only example of the 1963 Donzie 28 with an international reputation as a classic American offshore racing boat which represented the state of the art at the time.
31. Research indicates "Donzie boats connote images of speedboat excitement. Originally made for offshore powerboat racing, Donzie boats continue to make great waves among boating enthusiasts and even the boating media. Founded in 1963 by Don Aronow with a factory in North Miami, the Donzie boat served as an icon of America's greatness. Aronow, a legendary figure in the boating industry, applied his knowledge in building boats using fibreglass, in building the fist [sic] Donzie boats. Some of these notable designs that Aronow created for Donzie include the Ski Sporter 16, St. Tropez 19 and the 28 Sportsman. These models set Donzie's tradition for building boats with high performance and quality craftsmanship. To this day, Donzie boats are statements of quality workmanship, outstanding performance and distinctive styling.
...
Summary
...
Based on comparitors evident on international web sites, the standard having been achieved for the subject craft prior to being damaged, the stage of refitting the vessel that had been achieved, it's rarity internationally and it's credentials, the craft in my view including the trailer had an international value of about $180,000 AUD. On completion the craft would have had an estimated potential value of at least $220,000."

35What is readily apparent from a consideration of these qualifications and the form and content of Captain Kysil's valuation opinion is that the primary judge erred in admitting it in evidence. It was not admissible for the reasons put to the primary judge on behalf of the appellants.
36Captain Kysil was not shown to have had by training or experience any familiarity with the 1960s Donzi vessels which would answer the description "specialised knowledge" and enable him to express an opinion, by reference to the physical characteristics of the respondent's motorboat, as to its year of manufacture, whether it was an off-shore racer as distinct from a production version of the vessel, and whether by reference to the number manufactured or remaining in working order it was rare or unique. Nor was he shown to have had any "specialised knowledge" which enabled him to express an opinion as to the value of such an off-shore racer version manufactured in the mid-1960s; whether by reference to the price at which it might be bought or sold in the United States or on any other basis. His lack of those qualifications was a sufficient basis to require the rejection of his valuation opinion and any evidence he gave as to the year of manufacture and correct description of the vessel and its "rarity".
37Captain Kysil's opinion should also have been rejected for at least two further reasons. First, it did not as required by cl 5(1)(b) of the Code of Conduct, state the assumptions of fact on which it was based. For example, it did not state, if it was the position, that Captain Kysil was making assumptions as to the correct description and characteristics of the motorboat, as to the number of such vessels and as to the number remaining in working order. Presumably, assumptions along those lines lay behind his references to the vessel's "rarity internationally" and its "credentials". Nor does Captain Kysil disclose the underlying information as to the offer prices of the "comparitors" to which he refers or any specific characteristics of those vessels.
38Secondly, and more fundamentally, Captain Kysil did not give reasons for his conclusion as to value. In the absence of such reasons, his report did not and could not demonstrate that his opinion was based on any "specialised knowledge" which was in turn based on relevant training, study or experience. The reader of that report was left with no idea as to how the "international value of about $180,000" was arrived at or as to how reference to unspecified "comparitors", the vessel's "rarity internationally" and its "credentials" might justify such a value.
39It remains to consider Captain Kysil's oral evidence. It was accepted in argument before this Court that if, in the course of that oral evidence, Captain Kysil gave evidence of specialised knowledge based on his training, study or experience and explained how his opinion was based on that specialised knowledge, the evidence previously inadmissible may have been rendered admissible. He did neither.
40In cross-examination, Captain Kysil said that he had searched a number of websites to inform himself about the Donzi motorboat. That he did so was consistent with his having no relevant training, study or experience to express a view about the correct description of the vessel or as to its rarity. He explained that his conclusion that the vessel "may be rare" was due in part to the fact that the "information [he] received off the Internet was insufficient to give ... a more fulsome research background on the boat because there was insufficient evidence of the type of boat I was looking for" (Black 580). Captain Kysil did not identify or adopt as correct any information obtained from any particular website. Nor was it suggested or established that any of the websites to which he referred were sources of information which experienced valuers of Donzi motorboats treated as reliable and used when forming opinions as to value: as to the possible admissibility of such information, see English Exporters (London) Ltd v Eldonwall Ltd [1973] Ch 415 at 420; PQ v Australian Red Cross Society [1992] 1 VR 19 at 34-36; R v Fazio (1997) 69 SASR 54 at 63-64; Woods v Director of Public Prosecutions [2008] WASCA 188; 38 WAR 217 at [55]-[58]; Bodney v Bennell [2008] FCAFC 63; 167 FCR 84 at [92]-[93].
41Again in cross-examination, Captain Kysil sought to justify his conclusion that the motorboat was "about a 1963 model". He asserted that there had been off-shore racing models manufactured before 1964, that production models were manufactured from 1964, and that there were minor changes to the off-shore and production models manufactured from that time. He described those changes in very general terms and as being to the hull and cockpit shape to make the vessel "more efficient and faster in the water" (Black 587). He gave no evidence, however, which qualified him to speak as to characteristics of versions of the vessel manufactured between 1964 and 1970 which enabled them to be identified as manufactured at a particular time or as an off-shore racer rather than a production model. At one point Captain Kysil sought to justify his statement that "the profile of Donzi was at a very high level internationally" in 1963 as being "that sort of information that you glean over many years of being in the industry, working in the industry day by day" (Black 581). That answer does not describe "specialised knowledge" based on training or experience which qualified him to give evidence of the kind referred to. Ultimately, he accepted that his description of the vessel as a "1963 model Donzi" was based on what he was told by Mr Anastasopoulos which was "in addition to my own research" (Black 585). That "research" did not qualify him to express any opinion as to the year of manufacture or correct description of the vessel. What he was told by the respondent was an assumption only.
42In his oral evidence in chief (Black 561) Captain Kysil explained that his estimate of value was based on:
"... the crafts rarity, its design, specification, its origin, its uniqueness and status in the American boat market particularly as a significant early model offshore racing craft". (Black 561)
He agreed that the two comparable vessels to which he referred in his written report were 1967 28-foot Donzi vessels. Each was advertised for sale in February 2009, one for US$39,900 and the other for US$52,900. Those vessels were the same as those relied upon by Mr Munroe except that Mr Munroe had taken offer prices for those vessels as at May 2010. By that time the former was offered for sale for US$12,000 and the latter for US$49,900. Captain Kysil maintained that these vessels were in a "different category" to the respondent's vessel because it was an off-shore racing vessel whereas they were more standard production vessels. Ultimately he accepted that the defining characteristics which he had assumed the respondent's vessel had which those vessels did not have were that it was an off-shore racing vessel manufactured in 1963 and "rare". He was not qualified to express an opinion as to the correctness of either of those assumptions.
43I conclude that the primary judge wrongly admitted Captain Kysil's written and oral evidence as to the year of manufacture and correct description of the respondent's vessel and as to its value. The primary judge relied upon that evidence to support the findings that the vessel was one of the first boats manufactured by Donzi in the mid-1960's and was an off-shore racing version of the vessel. Mr Anastasopoulos' evidence considered alone did not justify those findings. That evidence was hearsay and, as is noted above, in cross-examination the respondent conceded that he could not recall how the vessel was described to him when sold. In the absence of any evidence which established its year of manufacture and that it was an off-shore racing version, and for that reason "rare", the vessel's value for the purpose of awarding damages could only be assessed on the basis on which Mr Munroe valued it, namely as "an early - probably 1960s Donzi vessel" (Black 653).
