Bobby.V Posted December 8, 2018 Share Posted December 8, 2018 Hey guys, Just bought my first boat. It's a pre-loved 3.7m tinnie. It's painted with house paint so I'm going to strip it back to bare metal and repaint but I am not sure what this bar is? Can anyone shed some light? Haven't seen it on any other boats... It's riveted in to the hull. Pics below. Thanks in advance Link to comment Share on other sites More sharing options...
kingie chaser Posted December 8, 2018 Share Posted December 8, 2018 (edited) Could just be a previous owner mod for some reason or a factory mod, probably to disperse wash although seeing the nice V of the bow it also could be to help lower in speed plaining?. That's my answer anyway Edited December 8, 2018 by kingie chaser 1 Link to comment Share on other sites More sharing options...
rickmarlin62 Posted December 8, 2018 Share Posted December 8, 2018 Its a spray chine to deflect water away from hull 3 Link to comment Share on other sites More sharing options...

Does it make a big difference? I've only got a 9.9hp on it so the boat won't be hammering along.. It's right in the way of the plans I have to paint and vinyl wrap the sides of the boat.. I'm considering removing it and plugging the holes with aluminium brazing rods.. Link to comment Share on other sites More sharing options...
kingie chaser Posted December 8, 2018 Share Posted December 8, 2018 It may not be in your 'plans' but its there for a reason. Id be testing how the boat gets up to speed & sits before taking them off. 1 Link to comment Share on other sites More sharing options...

zmk1962 Posted December 8, 2018 Share Posted December 8, 2018 +1 with @King chaser and @Sea Ranger. When it comes to boats I always choose function over looks. Looks will get you an ooh ahh from your mates. Function will get you fish and home when the conditions change. Cheers Zoran 1 Link to comment Share on other sites More sharing options...
Fab1 Posted December 8, 2018 Share Posted December 8, 2018 Another option is removing those spray chines and painting/vinyl wrapping the hull then replacing them again. I doubt if you completely removed them though you,d see much effect if any with such low hp fitted. Personally,id do what i mentioned above.

Hey @Bobby.V have you taken her out on the water? You may be surprised what your 9.9hp will do with a 3.7m tinnie (if correctly propped and trimmed). For comparison, I have a 15hp Aux on my 6.3m heavy fiberglass boat (with a 2500kg payload) and it will push me along at 10km/h. You may be pleasantly surprised what the 9.9hp will do with your 3.7m tinnie (2-300kg payload). I see that chine providing 3 functions - i. given the T profile it would significantly strengthen/stiffed that part of the hull ii. it would act as a chine - providing additional lift iii. it would deflect spray What ever you decide to do, I'd recommend it stays or is refitted after you wrap.

cfish Posted December 8, 2018 Share Posted December 8, 2018 I'd keep the spray chines on, you don't need to be going fast if you pushing into the wind and waves. Link to comment Share on other sites More sharing options...

Cheers Z Nope haven't even taken her out yet. Got it yesterday. I'll take it for a spin this afternoon 4 hours ago, kingie chaser said: Whats the boat anyway?? Looks like a Quintrex sportsman? Not sure what it is. Rego papers just say Telwater but obviously they own 8 brands under them including Quintrex, Stacer, Savage. It looks a little different to the Quintrex Sportsman. That has 2 ridges running alont the hull and mine only has 1. Anyone have any idea what It could be? Link to comment Share on other sites More sharing options...
back cruncher Posted December 9, 2018 Share Posted December 9, 2018 Hi all...if you going to take them off,i would mig weld the holes,oxy welding will put to much heat into the alloy and distort the alloy,migs alot cooler.if you put them back on i would sikaflex them back on.

campr Posted December 9, 2018 Share Posted December 9, 2018 Definately intended as a sprey chine but as it is riveted on I doubt it is original and my guess is its been added later in its life. Thats a lot of holes to put in a boat with potential to create leeks and electrolysis. Ron Link to comment Share on other sites More sharing options...
Sea Ranger Posted December 9, 2018 Share Posted December 9, 2018 If it doesn't leak now I don't think I'd take them off just to paint them. As above that would be creating a lot of holes Bear Link to comment Share on other sites More sharing options...
Great_White Posted December 9, 2018 Share Posted December 9, 2018 Could even be a stabilizer for when at rest .... I'd leave it on !!! GW Link to comment Share on other sites More sharing options...
Nolongeramember Posted December 10, 2018 Share Posted December 10, 2018 Looking at the spacing of the holes, I don’t think it was factory fitted. A past owner has added their own modification. You would have to question whether it does anything useful on that boat. Take it for a test and decide for yourself if you want it on there. Just curious, is there a matching one on the opposite side? Link to comment Share on other sites More sharing options...
kingfishbig Posted December 10, 2018 Share Posted December 10, 2018 I'd leave it there. You would be making a lot of work for yourself; either you will have to fill up a lot of holes somehow or find a way of reattaching it. Link to comment Share on other sites More sharing options...
zmk1962 Posted December 10, 2018 Share Posted December 10, 2018 Hey @Bobby.V just wondering if you have had a chance to take her out on the water and how she performed with the 9.9hp. That input would go a long way toward your decision I think. Cheers Z Link to comment Share on other sites More sharing options...

Didn't really notice the chines doing much.. although the water was quite calm when I took it out so they might do more in choppy weather Link to comment Share on other sites More sharing options...
zmk1962 Posted December 14, 2018 Share Posted December 14, 2018 Well that’s a great start - happy for you. Correct trim and weight distribution has a lot of effect on getting on a plane. The chines would definitely help planing if you had weight in the forward section of the boat regardless if it was choppy or calm. They would help deflect spray in a chop. Thanks for posting back and best of luck with it. Cheers Zoran Link to comment Share on other sites More sharing options...
Plethora Posted December 14, 2018 Share Posted December 14, 2018 it is a home made stabiliser - this function is built into later version of Stacer boats Link to comment Share on other sites More sharing options...
Bobby.V Posted December 14, 2018 Author Share Posted December 14, 2018 Just trying to decide what to do with them when I vinyl wrap it... I'll leave them on or re-fit, but I don't know if it'll be a mission to line rivet holes back up.. I used to wrap boats as a job so I'll see if I can slit the vinyl and wrap around the chines. It'll be a big mission but I'll keep everyone posted on the progress! Got paint stripper sitting on the paint atm, gonna strip it back to bare alum. Then vinyl wrap, casting decks. sounder, trolling motor and she'll be ready for a sesh! Link to comment Share on other sites More sharing options...
