Apparently Iboats WILL ship individual items if you contact them and ask nicely-but it takes a bit of sweet-talking. They thought that the shipping was excessively high until some of us pointed out to them that it's still a whole load cheaper to buy and ship than it is over here...

So where did the testing lead to?

What prop on a Tohatsu 50 ?

Trim tabs size and strut pressure?

gaviotapete · 26 June 2006, 19:07

hiya boatster and other sr4 hombres. i've just ordered the trim tabs and will post my results when i try them. so far though i was able to do 35mph @5900 rpm with about 140kgs/300lbs on board. i am curious though about whether or not these tabs are going to be a nuisance when launching and retrieving? have you had any problems? any tips?
thanks

Nos4r2 · 26 June 2006, 20:24

If you're doing 5900 rpm you sound like you need to go up a prop pitch. What are you using?

gaviotapete · 27 June 2006, 16:10

i dunno. could even have have hit 6100rpm for a second or two.
maybe i need a 14pitch? also wondering where to attach the smart tabs so that they're not too much in the way. any photos to show where they should be mounted?

gaviotapete · 27 June 2006, 16:49

Nos4r2, have you got any photos of the flooding hull flap arangement that you made? i'd like to rig one up for mine as well but i'm not quite sure
how. thanks in advance

Hi

Have a look at

www.ollysrib.741.com

some good pictures in the build sections

Nos4r2 · 27 June 2006, 19:37

I keep meaning to take a pic of that flap and keep forgetting...Eventually I'll remember...
I've done a (crap) diagramme here for you.

Have a look on Iboats.com forums for searider or search boatsters posts on here-there's more pics of Smart Tabs on an SR4 there.

gaviotapete · 28 June 2006, 15:55

thanks nos, i could'nt make out the diagram but will look on iboats forums

Nos4r2 · 01 July 2006, 02:13

Click on it Pete-it'll magnify

gaviotapete · 01 July 2006, 05:58

thanks for the tip 'bout the click nos. i think i've got it figured; its a 3 layered circular hypalon patch a bit larger than the transom hole that's glued to the transom just above that hole. or is the third layer merely
a rectangular strip that connects the transom and the round patch thereby creating a hinge? am i getting closer??

Pretty much but it's square rather than round-it just covers a round hole.It's stiffer that way.
All it needs to do is to be rigid enough not to get pushed into the flooding hull by weight of water when you stop but be flexible enough not to impede water getting out-hence the single layer as a hinge.

hey Nos, i just slapped on my version of your hull flooding inhibiter flap.
its more of a prototype really b/c i used sikaflex and some screws to glue the two pieces together and to the transom. will let it dry 'till the w/end
and then give it a sea trial. hope it works!?!

Nos4r2 · 13 July 2006, 03:48

Cool, that's pretty much what I've got on mine

hope it works for you!

after hearing about the trim tabs from boatster and then seeing how ollyit
installed his (on his helpful build page) i slapped some on mine and they are great. its an easy install and the performance of the rib is now better;
a bit faster, more stable and quicker to plane.
