I very much doubt it would be the plane and simple answer

Can you even fit 4 divers + 1 in a 4.9m?

I would think it would .... eventually. just don't expect to water-ski off it at the same time

I had a 5.5 humber with a 60 towing a 6.5m rib + 5 divers on the plane from Angle to Dale in Pembrokeshire took a while to get going, just inched the throttle up bit at a time, it was glass calm though.

They should have had 2 batteries or switched off all electrics off while they were at lunch :P

I think it will, my old tornado 4.8m with a 50hp Yam triple did. It was 6 up with 30L of fuel and some other junk on board. Just took a bit longer to get up there...

dont see why not, we regulary have 4 divers and a cox in a 5m humber with a 60 yam on the back we all have to sit forward to get her on the plane but she gets up easy.

Is the 17x13 the right prop for a more casual load? If so, then you might consider dropping a couple of inches when you go to the "need another boat" diving load. SHould help quite a bit with getting on plane, but you'll need to keep an eye on max rpm when you're cruising.

I used to have a 5.3 with a 60 Yam and regularly carried four divers with twinsets and kit plus 75lts of fuel at 24knots.
Can't think why anybody would think a smaller lighter boat wouldn't do just as well...
