I live in Mordialloc about 15-20min from Frankston. depending on which way the winds blowing we could have a run around Franger or Mornington. My SIB is on a trailer, I tried previously to go without one and it just made life too difficult. Even with the 340 only weighing 55kg the packing, unpacking is the very last thing i wanted to do at the end of a long day. I can assure that my quicksilver is in A1 condition, always garaged, no abrasions or patches. I have put in a layer of foam with marine carpet on the marine ply floor which make a big difference when being knocked around.
I'd probably go a 3.8 or even 4m quicksilver with a 20-25hp second hand, as new boats are a rip-off!! Im not really into importing goods, so id probably try to find something locally.
i'll pm you my number, im not 100% sure whether im selling up, but still happy for you have come out for a run and get an idea of this particular setup
