Some people say (to quote Clarkson) they were a heavier lay up. Some tales of some the newer ones hulls flexing - noticeable when lifting on drystacks. Possibly just the good old rumour factory though !!!
Electrics/wiring not the best ,,, usually standard auto bits in that era but I did my own. Have a look in the console and under the chaise longues
I do like my Cobra and it serves me very well. It's not the nautique like this one so a bit lighter ,, but with ropes anchors oil, half a tank of fuel and all the go withs it's 1200kg so i would expect this one to weigh even more .and as regards the 135 it could be ad others say a tad underpowered and thirsty. A 150 would be better but my old dive club runs a cobra with a 135 opti and lug 6 divers and kit around on it. ,,,, deffinitely no speed records
Sea trial :-)
