Me too, '68-'72 or thereabouts in my case. I've only put on 3 ˝ stone since then but I am only 5' 6"  Cry

Wooden masts back then, we used to go up to the club early to glue some wood to the sides or front to stiffen it up then next week we'd plane it off again  Confused rig tuning really meant something back in the day. As you say "happy days".

Yep.  Great initiative.

Good to hear that they have removed some of the rake from the rudder.  I used to fall in a lot on gybe marks as the boat would wheel around and then the boom would hit the water with inevitable consequences.  Happy days!

All credit to the OK Class Association and donors for making the loan boat happen.

Would hate to be the first person to put a scratch on it though.

Depends what you regard as being reasonably competitive Smile. Older wooden boats, assuming they are not rotten or anything seem fairly easy to get up to speed, usually just needing a carbon rig which allows the rig to move forward slightly (carbon masts put less weight in the bow compared to metal masts) and changing the older swept back rudder to the newer less swept back design. Moving the rig forward and changing the rudder help reduce the weather helm a good bit.
Older polyester GRP boats will no doubt be a bit harder to get up to speed as more likely to have gone soft or gained weight compared to a wooden boat.
How much you spend on a carbon rig will depend on what age the mast is as they have developed since they were introduced as you'd expect.

To see what can be done have a look at https://www.okdinghy.co.uk/news/demo-boat/
The boat is from 1993 and after the refurbishment seems as fast as anything else when people have sailed it at open events


nice to see what you can do with an old boat! I fancy a single hander to keep on the beach and use when there's no crew handy, I don't want to go laser, or solo, always thought OK looks nice.
in terms of "reasonably competitive" what I am looking for is something that will do alright in club handicaps, and not give me the feeling that the boat is holding me back excessively, I am probably not likely the turn out for open meetings, unless they are on my doorstep. A fundamentally sound boat, with whatever mast it comes with, I would probably invest in a new(er) sail and be happy to upgrade running rigging etc' Don't want to invest too much, in case I don't get on with it - if money was no object I would be knocking on Ovi's door

Yes; many classes do this ... it's quite and accepted way to trim your mainsail.

Tasar's are set up like this and this is much discussed in Frank Bethwaites book which is one of the best texts available for small boat speed ...

I remember an Aussie fireball in the 70s with the traveller from a yacht, when correctors are maxed, more weight was needed!

Hi Kazrob
A credit to those generous people and the work done. As I found for the Phantom if you ask politely and don't expect the marine trad people want to help.
