So we bought a Pacer dinghy :) Thanks for all the advice from people last month: it was very much appreciated.
When I and my husband took it out for the first time (he can't sail), I managed to rip the main block right out of the centreboard casing. It was screwed into a too-thin piece of wood and it tore out as I shouted at him to Sit Down!!! Don't Move!!! Pull That Rope, No, THAT Rope!!!
(This, by the way, completely blew out of the water his claim that he "had sailed dinghies before"....)
So took it back to the guy I bought it from, who was lovely, and did a thorough fix. The second outing, kids in tow, was much smoother sailing :)
Anyway, now I've had a go with it I have identified some things that need fixing pretty fast, or they will drive me nuts. So I'm going to Whitworths tomorrow, but I'd appreciate some advice.
1. This cleat for the main/jib halyard is broken, but I can't find any like that on the Whitworths catalogue. A replacement will have to be rivetted onto the mast. I wonder whether something like this will do:

2. There are two pulleys around the bottom of the mast. Any idea what they are for? I wondered whether the one on the left of this photo, which is at the front of the mast, is to use to get more purchase on the main halyard, but that seems like overkill on a dinghy to me. The left one, which is on the port side of the mast I have no idea about. Any suggestions?
This bailer has a slow leak even when closed as tightly as I can close it. Any ideas? The kids find it upsetting to see water coming in...

This bung leaks, though the other one doesn't. Any ideas? I think I'll try cleaning it out and screwing it in really hard before doing anything else. Are these actually useful? I could seal it in with silicone easily enough, I think, but then we would have to leave it in all the time.

I also have to get me a new jib sheet (for sure) and new rope for the halyards (if I'm feeling rich). But those are easy enough.
Does anyone know of a paint shop where you can get sample sized pots of different coloured outdoor paint? When I looked I could only find sample pots for indoor paints. I think the outside (yellow) is an enamel and the inside (blue) is something else. I'd like to be able to sand/repaint a few obvious spots.
Thanks for any suggestions :)
