There are more than a few GRP displacement motorboats like this around, most can be had for not too much money, most have an inboard diesel and would make a comfortable if steady cruiser for the protected waters around the Solent.
If there is one drawback it's probably some of the details, notwithstanding the overall shape of the cabin roof and dog house, details like the rubber fitted windows to me are all too reminiscent of kit cars in the 1960's and 70's (apologies to US readers that particular motoring phenomenon probably and fortuitously passed you by).
None the less a sound little boat.
