Hello all,
Does any one have any good tips on Sanding hulls? I am particularly interested to hear about sanding on curves (concave and convex) and avoiding "flat spots".
Advice gratefully accepted.

Andrew.....very few have a robotic [3D] mind to sanding hand relationship, however a flat cork board for concave & a thin contoured cork board for convex profiles will always assist when sanding to achieve the perception of an ever changing flatness %% on these surfaces
Naturally the material being sanded always varies in our visual perspective ...wood can change colour/tone as the contour changes & create sometimes false visual impressions of smoothness or flatness
Same applies to fiberglass surfaces............one trick to consider is as the trueness to final shape gets close ....spray the surface with a suitable undercoat & let dry....this helps in hightlighting any contour defect & provides a witness in the reclamation sanding process.....sometimes you may remove 80% of your first undercoat...& need to apply successive coats.......good luck....Derek :-))

I have some rounded sanding blocks, and use these on convex curves.

Have a couple with garnett paper stuck onto chipboard blocks with double sided tape and some with the abrasive stuck onto hard foam rubber blocks.
Regards Ian.

All of the previous advice, tools and equipment plus my contribution:
Go steady, take your time and do a lot of feeling and stroking as well as looking - look upon it as a pleasure and not a chore.
Oh! and wear a mask....

Thanks everyone for the hints and the encouragement. :-))
A few therapeutic hours ahead of me very soon I think. %) %)
