But you've already got the definitive Cherub for sailing with a pole kite... I just had a symmetric kite made by Caws, and you could get a pole made up for a fraction of what putting this one together would cost you...
I may try and look at this boat. Should it be the 1971 foam Jennifer Julian Shell its worth preserving, should it be a Forman8s its possibly worth collecting and making available for someone who wants a project. But should it be one of the horrible CSM glass boats that were made, as is most likely, then it really is a skip job.
If you want a pole kite boat then reasonable wood boats come up from time to time and are far far better... I've just put a new interior in my IC. I never keep the bills, because it depresses me, but I reckon it cost a good couple of grand, even with the same rig and most fittings. Putting a bare shell back together with no rig or gear is going to cost you at least 4K... You can start with this bare shell for 65quid, spend 4K and end up with a boat worth 1K, or buy a new shell from Bloodaxe for probably under 2K, spend another 4k and end up with a boat worth 8K. It shouldn't be a hard decision!
