It is with these considerations in mind that I turn to the construction of the clause, and to the resolution of the problem in these cases, which is essentially whether the clause should be given effect to as expressly providing for an overall rate of discharge for the whole ship, the reference to "basis five or more available workable hatches" being treated only as qualifying that provision in the respects proposed by the owners, or whether that reference should be treated as overriding the provision for an over all rate of discharge, substituting for it a rate per available workable hatch. In truth the point is a short one, and it derives from the fact that the clause, which retains from its original form an overall rate of discharge which is then qualified by the words "basis five or more available workable hatches", has built into a tension between two different kinds of discharging rate. This gives rise to a problem which has to be solved as a matter of construction, but the meaning of the clause must also be to some extent a matter of impression. In this connection it is of some interest that, in all three cases, the construction favoured by the owners appears to have been unanimously adopted by the arbitrators. In the case of General Capinpin the arbitrator appointed by the charterer was Mr. Clifford Clark, and in the cases of Free Wave and Proteus the arbitrator so appointed was Mr. Cedric Barclay, both to hem commercial men and arbitrators of exceptional distinction and experience. Although there was disagreement between the arbitrators in the case of the Proteus, it is legitimate to infer (Since Mr. Cedric Barclay was also the charterer's arbitrator in the case of Free Wave, where there was an agreed award) that the disagreement in the case of the Proteus must have been on another point. It is plain that what really struck the arbitrators was that the clause did indeed provide for an overall rate of discharge, and did not expressly provide for a rate per hatch, despite the existence of well-known authorities dealing with clauses which so provided. They were simply not prepared to ignore the express provision for the overall rate; they preferred to treat the reference to "available workable hatches" not as substituting a rate per hatch for the expressly provided overall rate for the ship, but rather as imposing a qualification upon it. This was the reaction of commercial men, who must have
