caption_attribution_description: English: Colin Archer yacht JÆRBUEN II ex NANNA built 1898 by Archer in Larvik, Norway. Length over deck 43,6 feet, beam 13,5 feet (13,30m x4,10m). Sail area 140 sqm. Displacement 20 tons, Ballast keel 6 tons.
context_page_description: Colin Archer was a Norwegian naval architect and shipbuilder known for his seaworthy pilot and rescue boats and the larger sailing and polar ships. His most famous ship is the Fram, used on both in Fridtjof Nansen's and Roald Amundsen's polar expeditions.
context_section_description: Colin Archer built about 60 yachts, each to a unique drawing, half being double-enders and the other half with counter sterns. Many of both double-enders and the counter stern yachts have plum stems. All yachts have more undercut forefoot than the workboats, especially after 1897.
  The beam is 22-30% of the length over the deck. (As opposed to 33-36% for the pilot-boats and the rescue boats).
  All yachts, except the Asgard, and all pilot-boats, are cutter rigged (one mast). The yachts have their main boom extending the stern for several feet that with a relatively tall mast enhanced performance. (The pilot-boats' boom normally extends the sternpost by one foot. Only the rescue boats and a few fishing boats, are ketch-rigged (two masts)). The sail area for the yachts is in the range 100-125% of waterline length squared.
  On almost all boats, Archer spaced grown pine frames 2 feet c-c with a thin steam-bent oak rib between. This, together with thin, canvassed decks, made the yachts fairly light. The yachts have large ballast keels and normally no inside ballast, except a little for trim.
