  • 'Sprats and Minnows'
    ‘SPRATS AND M INNOWS’ SOME S & S SMALL FRY BY PATRICK MATTHIESEN Last year I touched on the ‘pocket cruiser-racer’ of approximately 30ft LOA which many had considered to be the smallest practicable size for minimal comfort and safety, particularly with the vastly more Spartan early designs. Yet, as has often been pointed out in the past, there is an equation which simply does not work and it is this: Enjoyment + HCF 1 = LOA + Beam + SA x (£+$+E). In fact there are many able mathematicians who would argue the converse and that is that maximum enjoyment experienced when sailing is the LCD 2 of LOA ÷ Cost. Thus, wise sailors have long known that they are faster onto the water, spend less time commissioning and therefore enjoy more sailing closer to the water if their boats are small. The headaches are lessened, equipment costs a fraction of that for larger vessels and most jobs can be executed on a ‘do it yourself’ basis 3 Manhasset Bay O.D. Construction plan Copyright S&S Inc. The very first S & S design #1, The Manhasset Bay O.D. falls into this category. The contract was arranged by Drake Sparkman, Olin and Rod’s future broker partner (the partnership was not formed till the following year) at the Larchmont Y.C. The boat is a daysailor/racer rather than a cruiser, but she was the first of the breed and S & S never lost sight of the impecunious family man who, by buying a pedigree product, might later move on to bigger, and some would say better, things.
