My father is selling his small 20ft yacht having finally decided that it's too much hassle to launch and recover - he's in his mid 70s now. However he would still like to be able to get out and potter around on the water now and again on a nice sunny day.
I've suggested that he considers a biggish SIB (3.5m - 4m) and while I know very little about them there seems to be a decent choice - something like the Excel Vanguard 395 or the bigger Honwaves would probably fit the bill for sensible money.
However the main element of cost is going to be whether or not he needs to buy a new motor. I've just come away from a Google search slightly open-mouthed at the cost of a nice four stroke 15hp motor, and I wondered how a boat in this sort of size range would perform with a small outboard - he already has a 2.3hp engine for his little tender. My 4hp aux will push about a tonne of Vipermax along at about 4 knots on a good day - what speed would 2.3hp achieve in a light SIB, 2 pax, total weight of boat pax and engine maybe 300-400kg? Planing is obviously not on the agenda but I wondered what is realistic.
Any thoughts welcome on choice of boat, suitability of existing motor or (if completely unsuitable) what sort of HP would be a sensible minimum so I can present him with some ideas and prices. Thanks
