to respond to yr questions:
1) the Javelin 16 is still on production (see BIMARE web page: www.bimare.net);
2) the quotation provided is valid;
3) the Javelin 16 is basically an unirig F16 (the sloop version is not offered).
It does not comply with with the F16 rule for:
1) its mast height (9,00 m instead of 8,50 m);
2) its gennaker (hooter) whose SMG is < 75% SF.
Other measurements are not at F16 HP limit:
for istance width is 2,25 m and mast and mainsail surface is 14,00 sq (instead of respectively 2,50 m and 15,00 sq).
In overall I would say that the Javelin 16 is better suited for solo sailing than a full compliant F16 HP (the furling gennaker makes life much easier).
As a consequence it should be much faster close to the wind al least until its "Code 0" can be unfurled.
