Thank you for the warm welcome.
What SIB/Outboard are you getting? I'd love hear about you new setup once you had time to try it out
100 m of soft sand was probably a bit of an exaggeration. The 2.3 hp would push me along at 7 km/h and I would always choose the launching site nearest to my destination - no matter the condition. The 8 hp should get me on the plane and allow me to pick actual slipways or at least better launching sites further away from where I want to go. So even though the 8 hp is a bit heavier it will hopefully make launching easier.
There are a few places I want to launch but cannot park the car close by where a bow trolley could come in handy. I also use the SIB for spearfishing as and I would like to be able to load all the gear in the boat at the car which adds quite a bit of weight, especially if I'm out with a mate, and it's not always possible to place all the weight above the transom wheels, so I think a bow trolley would be very handy.
