A large number of drawings are available for the Ohlson designed 5.5s. However we are well aware that the list is still incomplete, so regard it as work in progress. 

For many boats there is a “master” design available. We have tried to display this as good as possible according to our understanding. As there is no design register for the design office the drawings will remain the primary source of information on our way to a complete design register. 

Groups of boats we particularly regular before the various Olympics as orders were plentiful and boats differ in what might be regarded as small aspects like changed keel designs and positions, modified sail plans and other changes. 

In rare cases only a sail plan is available but this may refer to a boat from another designer for which the office developed a modified sail plan etc. Still a design number was issued for this boat

With lots of help we have tried to depict the boats by their initial sail number to individual sailors. This was possible through explanations on the drawings but inconsistencies may remain. The best way to achieve clarity is to search the 5.5 m IC World Fleet Online Database with the adapted (new format) sail number, as this provides better information on each boat and its fate. As good as possible we have been able to match individual boats to first owners and yards who built the boats. 

AND…. we are missing drawings for some boats known to the fleet database but we are missing the drawings, This is most prominent for NOR 24, ILVA, which has been the reason for a court case on plagiarism as allegedly the hull plans had been copied to develop the ILVA class in Denmark. But plans for other boats are missing too. So we search more information on S15 SHA SHA V, D 9 WEB, US 23 GOSLING and S30 RUSH II

 We would be delighted to receive additional plans should they be available.
