SIB Not planing

Hi to everyone, New here but hope to be on here much more often.

Just bought one of these,
Inflatable Dinghy River Boat Tender w/ Aluminium Paddles & Flooring Family Size for 4 Adults and 1 Child: Amazon.co.uk: Sports & Outdoors

And I must say, it seems a really well made bit of kit. As some of the reviewers mentioned, the floor plates doo have some sharp edges but 10 minutes with a fine file and all sorted.

Reasonably easy to assemble although the side pieces on the floor can be a bit of a pig to clip into place.

Also, the supplied pump seems to keep the valves open slightly so when you're inflating it, there is air constantly escaping which means you have to pump like crazy then quickly remove the adaptor before too much air escapes.

Apart from that it seems pretty good. However, on testing it this week with a brand new Chinese 6hp 2str, it wouldn't get on plane with myself and a teenager in it.

So, can anyone comment on whether I should expect this to plane with a 6hp or not and also, is the valve/pump not right??

I haven't tried it one up as the weather was poor later in the week.
I've tried shifting weight and still couldn't get it on plane.

Has anyone used Doel fins (or similar) and did you have any luck.

Don't really want to go to bigger engine as the weight of this one is about as much as is comfortable. I could carry more but it would make it become a grind rather than a means to an end!!!

Thanks in anticipation.

Paul

Thats a big sib to get on the plane with a 6hp motor.

Doel fins are marmite, love em or hate em, but if its just on the edge of planing they may work.

Lots of people will be along shortly to tell you their boat planes with a 3hp or similar, but my feeling is you need more power. 10hp should do it, but since they are similar price and weight, 15hp (Mariner, Mercury, Yamaha etc) would be best.

If you are going to stick with the 6hp. just enjoy the boat as it is, lots of fun still to be had at 6kts.

Yeah, there was a reviewer on there saying that theirs planed with 4hp and I remember a mate of mine 20yrs ago who had an inflateable that planed with the old evinrude 4hp twin cylinder. (I had the same motor on my little cathederal hull boat but it wouldn't plane except at full throttle with me hanging over the front and steering by leaning side to side!!!)
One of the reasons I bought it was because I wanted to get up on plane for a bit of fun.


I'll still enjoy pottering along but would like a bit of a thrash now and then, I guess I though 6hp would just about cut it based on a memory from 20yrs ago!!

As a kid I could plane a ZED 31 (Zodiac 310) with a 4hp, and a few years ago I got a Honwave T27 to plane with the same engine -by hanging over the bow with a loooooong tiller extension, but it wasnt very practical (and fell off the plane with the slightest headwind, wave or weight shift).

Your best option for power V weight is a used Tohatsu 9.8, they are only 26kg and should easily get your boat on the plane with 2 up.

hi, where are you, and where do you take the boat? my 3.2 planes ok with an 8hp on the back though i did have to put a smaller prop on it - may be worth trying as its like dropping a gear in your car to gain more acceleration

Landlocked, I'm getting a bit too old too lean over the bow and steer by leaning side to side these days!!!


Festinghouse, I've just been up to Keswick for a few days as the caravan site is directly onto the water. I'd like to find somewhere closer to home to use it though really.
I live in Chorley Lancs and on boatlaunch, there didn't seem to be anyhere close that took my eye.
We're only 200yds from the canal but it seems that a licence is not cheap to use on the canal so that's on a backburner for now.

By the way, a smaller prop may not be an option as this is some cheap Chinese copy engine so not sure what would fit!!

i would suggest knott end as the best local place to lauch. i too have thought about the canal as botany is just down the road from me but never had time to sort anything out over winter. best bet would be to take your prop to bill highams and see what they say

We must be neighbours!!!

Knott end sounds like an OK place but I've avoided the sea for now as I just want to convince myself of the reliability of this Chinese engine first. I'ts easy to row to the shore at derwentwater but easy to get dragged to sea with no power elsewhere!!!

So where is Bill Highams then? Might have a look/see.

its not too far from us - ten mins off the m61 and they literally have a room full of props all different sizes. if you want then fetch your boat down to holyhead and i will be your safety cover in case of breakdown
