For interior space and comfort there are very few yachts of similar length that can compare with a VDS 34.
Mine is a steel version with deep keel and spade rudder which I believe is the original design configuration. Shallow draught and skeg hung rudders are an accommodation for inshore cruisers.
The alloy and timber versions are .9 tonne less in displacement but carry .2 tonne more in ballast and therefore have a better ballast to displacement ratio and should perform better than steel versions.
This assumes that the original design has been adhered to. Consideration should also be given to whether the yacht has the taller fractional rig or the sturdier mast head rig.
I spoke with somebody a few years ago who said the alloy versions sit too high in the water. This may or may not be the case but they would have a greater payload capacity which would offset it.
Unfortunately I have not had mine in the drink yet but I have been told there is not much to pick in sailing performance between a VDS 34 and an S&S 34.
Sounds like you had a great trip and with 5 people aboard and all that gear, you have done really well.
I look forward to hearing more of your adventures and having some of my own.
