It takes 2 of us about 20mins to set the boat up and about 10 mins to put it away again.
Go for a set of transom wheels - they are BRILLIANT!!!
I have seen nearly 30mph on the GPS on flat calm water - also uses only a tiny bit of fuel.
I agree that on engines of this size a 2 stroke would probably be a better bet although I am very happy with the 4 stroke - it does smoke for about 5 seconds on startup due to it being laid flat - it has been in the boot of the car since I bought it - about 3 weeks now.
Look out for S/H bargains - picked mine up for £1050 used 3 times!!!
They are very stable and great fun - have been out in 4 foot waves no problem - longest trip so far about 5 hrs covered about 60 miles.
Really only wanted the engine as an aux but got a boat with it - intend to take it to Spain/Gibraltar Chriostmas time - may pop across to North Africa!!!
as discussed the extra keel length makes the 3.4 a bit better in the solent chop.........
forget blatting around in anything too rough as the keel is so shallow it gets quite uncomfortable and it is not really shaped for cutting thru the water, but if you hold on tight and dig your feet in so to speak it is amazing how fast you can go in fairly difficult waters....but are best on a nicer calm day....great for surfing up and down nice big swells, chasing bigger boats that can only go a bit faster !!, jumping their waves, never gps'd mine but it does blat along, have a gps coming soon for it (handheld) so will be able to check out the speed.
i would say the slatted ones are probably slightly stiffer but when you are blatting around on an inflated rubber baloon they all give a fair bit anyway so given the choice i would stick with inflated floor for ease etc
now one issue i have had with the 15 yam is it sprays up at the back a bit over the tubes so i raised the engine 1 inch with a bit of wood and it is fine now,
also make sure they are selling you the latest model, the one with the tubes that taper down like in codder pic at the back so more tube is on the water. white with blue rope is nicer than grey but might get dirtier if left out
