Crew weight for a Tazar?

The boats take a good range of weight, and also a good range of hull age.

Neil Spacagna was national champ at around maybe 30 stone up

I had a blasting day 34 stone up one day - we ran rings around RS200s.

In v.light winds with around 26stone we could get off the line quicker than 400s

The trick is to know how to plane up wind and to know how/where to keep the flow (qaurter wave) attached to in light. Design wind is 9 knots with about 20 stone if i remember right though. FB and IB designed it for man-wife or adult-teenage sprogg combinations.

A ligth crew will plane upwind at a lower wind speed but of course as it builds up the heavy crew will hold more power.  In very light breeze it's more about getting the hull trim right and the sails flat, and most of all , putting the boat in the right place and carrying way through the holes than outright weight.

If you are borrowing a very old tasar, I'd check the toe straps , the rudder pins and the wood inside that takes these, the shroud tracks, the main sheet block flange and the traveller,  and also the general deck bond- these are all a bit prone to breaking with heftier all up wieght as I found out!
