I have the Honwave IE 3.8 + Honda 20HP and IMHO it is an excellent, robust and steady boat.
Many people in the boating community view these SIBS as glorified tenders which is a load of rubbish. I bet I spend more time on the water than most of the owners of a bigger vessel. When I go down the Hamble River on a nice day most of them appear to spend their entire weekends sodding about cleaning, painting, launching or rigging sails.
My little SIB takes 5 minutes to launch from trailer to water and back again...and that’s alone... with two adults up I have done some great all day trips 30 miles + and apart from the deep ocean I go where most of the bigger boats go along the coast and better – and all on a fraction of the cost of a bigger boat.
If I see a nice beach I simply land – flip the transom wheels and have a picnic.
I would not rate it as a bottomless pit either, once you have the kit – life jackets, flares, VHF apart from fuel, engine service and launching fees that is pretty much it.
