The first sea trials of Knierim’s new P 33 had been eagerly anticipated - and the boat’s performance did not disappoint either spectators or the test crew.
During the sea trials, “Zephyr” - the silver-coloured first edition of the new Knierim model - reached its target of 7.2 knots upwind speed in a moderate breeze of 12-13 knots on flat waters. The required power was provided by a square-headed mainsail of 37.8 square metres and the 7/8th size code 1 jib. More than 50 percent of the 2.6 tons displacement is ballast. The stainless steel fin and the lead keel bulb were milled in the company-owned 5-axis milling machine of Knierim Tooling, as was the mould for the hull. It is constructed in carbon fibre of SGL in a sandwich technology. Line drawings came from the Judel/Vrolijk design office and were based on VPP and CFD calculations.
