The 5.4 takes allot longer (or so it seems to me) to empty compared the 4m I had.

Yeah by 1.4m
What I'm getting at is you can't just zip up and off like you can in the 4m with the hull open. You have to build the speed up slowly.

I haven't helmed a Searider for ages, but I seem to remember the 4m that we used would take off with quite a "woosh" onto the plane. Back in those days Seariders were the only RIBs we had in service, and that sudden acceleration was recognised as a hazard, worthy of special briefing to people helming them for the first time.

Is this still a factor? I'm not sure how much that was due to the flooding hull emptying. It was explained as such, but of course we didn't have any non-flooding RIB to compare it with.

It will be a hazard if your not aware, I nearly fell off the seat yesterdat.
If you give it a fist full of throttle it points skywards, the water drains then you shoot off. It was great fun but i just let it drain slowly until I found my feet!

With the 17 inch standard Yam prop on my 5.4 takes off without any hesitation. With a 19 there is a slight hesitation but not very much. I have recently put my 50 ish litre tank in front of the consol which seems to have helped the balance as well. I will have to wait and see if there are any adverse effects in a large following sea.

With the 60hp I had on before it was a different story and very sluggish if you had more than 2 peeps on board.

I keep mine open BTW.

I had 5 gallon in the bow but next time I would take 10 gallon, either a 2 5 gallon tanks or a tank and a 5 gallon water container.

Hi,

i closed my hull , when rebuilding the transom.
My engine is a elder premix Yamaha 75HP with trim.
2 20Liter tanks in the back. My ownbuild console , now in the middle.
Console weight approx 60kg.
Prop 13 1/2 x 17

Accelleration is outstanding.When changing from 3000 revs to full it is dangerous without the backrests.
As a leishure boat it is not usefull. It is very unstable while laying in water. I tried to fish in the Croatian Adria last week with my brother. Every move will change the hull from left tube to right tube and back. With my load, the tubes will only touch at the end the water.
I think about open it again.

Unstable ????Bloody hell have you ever been in a hard boat the same size? if i stand on the gunwhale of my mates 17 foot mayland it leans over at about 40 degrees and everything slides over on the deck and makes it worse
