Planing with an f-rib

Hi. Looking for some advice please. I currently have a 4m aluminium floor honwave with a 15hp 4 stroke. Weighs about 140kg all in. Use it for Scottish West coast, islands etc. It's great but the usual problem of it being a pain pulling up beaches - i have to take engine off every time and so on.

I'm looking at getting the folding rib 360 (48kg) with a 6hp 4 stroke (25kg) so that I have that as an option when I'm staying close to shore with less people/smaller loads. I can also get it in boot of car no bother.

My question is do you think the 6hp would plane the folding rib with 2 adults and some minimal camping stuff? I don't want to get a bigger engine because the weight seems to jump quite a bit when they go 8hp+
Thanks very much

I'd ask the Gurnard - he's just up-rated the engine on his F-rib from 3.5 to a 6HP Yam. He's posted some great threads in the Rib Gallery about his boat & forays.

Hi duggie..thats an easy question to answer..and F-Ribs are very efficient boats..but there is no way a 6hp will plane the larger F-Rib..two up and camping gear...you will need to look at a 10 or possibly a 15 to make sure

My F-Rib 2.75 which is a good bit lighter ..and easily planes with just me and my gear...with a 6HP. I doubt it would plane two up ..but I have not tried

Soon as you go two cylinder you nearly double engine weight but you need the extra hp so it's a catch 22 plane or not to plane? But you will still save around 50 kg less than your current rig.

Cheers

It's true - still a good bit lighter than the honwave

Found a place in the channel islands that suggest they can sell a new 9.8 tohatsu 2 stroke - 26kg. I've emailed them to ask how I can buy one

Thanks guys

Mainbrayce? You order - they send. Simples.

Big money though!

Look at the Suzuki 9.9 38kg twin cylinder with a big foot option for heavy loads 1650 better on fuel so you can save on weight by not having to carry extra fuel plus 5 year warranty you will only get a year with the two smoke I would think and it's in the channel isles pain if it breaks OMO.

Cheers

Planing with an f-rib

A cheeky new 9.8 from Mainbrayce is a good choice.
Or a nearly new secondhand one here might be good if price is negotiable.

These little motors rock....26 kilos and run as sweet as a sewing machine.

Don't rule out the Merc/Mariner 15hp 2 stroke - speaking personally my favourite SIB engine and the lightest 15 at 36kg. 1100/1200 will get you a nice one and looked after you should never lose money on it.
