Lesro Javelin
SLEC will sell you a Rapier plan, if that's of any use to you 200TDi.
As Bob and Harry have said, the hull is the same, just from the deck up that differs.
Alternatively, SLEC will sell you a Lesro Arrow plan, that's the Javelins' smaller brother of the same design.
You could then get that scanned and blown up to the same dimensions as a Javelin.

Far too many projects, nowhere near enough time or skill!
