Thread: Boat Trailer project

    Re: Boat Trailer project

    I will do some shopping around. I have only had one quote from a company on the northside.

    Shop around, I feel the $2.90 is not a cheap rate. Give them the sizes of the trailer and ask what the 3d rate is for that item.
    I think all galvanizers in Brisbane are running 10m + baths these days.

    Re: Boat Trailer project

    I have 12" DEEMAX SS brakes on my cat trailer - couldn't be happier. Been approx 12 months now and absolutely no dramas. The ventilated rotors and calipers I purchased from Ivan at FMS Trailer at Seventeen Mile Rocks. I priced Titan Brakes (which are Kodiak) at Cleveland I think, and what a ridiculous price he wanted. The DEEMAX are pretty well identical and a lot less. Just looked up my invoice from Ivan and this was the price.

    To Supply 2 x Dexter hub kits with 4 x dacromett 6 stud hubs 4 x stainless steel 12" ventilated rotors and 4 x stainless steel calipers $2014.

    Your welcome to give me a call anytime - just pm me and i'll give you my phone number.

    Also I had an Aluminium trailer built in Caboulture by Peter Winn at Winning Yachts.

    Re: Boat Trailer project

    Thanks for the information Adrian. Good to hear the brakes are good.

    It's costing me $2500 for the brake set up in full S/S and that includes the two axles which are stepped. The axles are about $300 each so the price from over the boarder is pretty good. Have your brake pads got s/s backing plates?

    I too checked the prices out on the titan brakes and it was going to cost $1500 a wheel and that was without hubs. They must be made of gold !!!!!!!!!!!!!! I am glad you mentioned the titan brakes as I was beginning to think that I had missed something as I too could not see much difference in the design or manufacture of them compared to others.

    I have seen a few of the trailers that Peter has built and they are nice gear.

    As for the pads no they do not have ss backing plates and Ivan did not know if they were available. Maybe a email to DEEMAXX in the US will confirm.

    good luck with the trailer build Brett, nice project for you.

    Just on the boat weight thing, the 7metre Cruisemaster on it's trailer, ready for cruising, is every bit of three and a half tonnes. As you know, these boats have everything aboard...including the kitchen sink!
    Great boat btw, very capable offshore as well.

    Yep your right about the weight Mal. I will be over the 3.5 ton so I am building the trailer for 4 ton. The trailer I am building is heavier as the production trailers are made of thinner wall materials to get them down to comply with the tow regulations but are not what I would be happy with towing any distance which is the plan. The gentleman that has lent the trailer to me also gives me the use of his 200 series landcruiser with a petrol v8. Only good for 3.5 ton and without even going over a weigh bridge it would be over. Just with full fuel and water it add another 500 kg on. Although the landcruiser tows it fine I will not be complying to Transport regulations and if I were involved in a accident my insurance would be nil and not to mention if someone was killed or badly injured I know where I would be heading. So the tow vehicle I will be purchasing will now be a small truck so I and other people are safe and comply to the regulations. I am in the process of looking for a small truck which I can also use around the house as I have a large block that the wife has filled with many gardens which I have been told I must maintain.

    Have had the boat out a few times and it does handle the conditions well. I got her so I could go out for a few nights with some comfort. Nothing better than having a hot shower and a hot meal. Not a boat to buy if you want to go sport fishing in a big way but I certainly don't have any trouble fishing 3 people with rods out of it. Have been slowly setting it up a little more for fishing tho. I turn it back into a caravan for when the wife and I go out for a run.

    You had much to do with them as I am using 42lph at 20 knots which I think may be a little high. I am running a 5.7 l mercruiser and produces 350hp.

    Just got price back to galvanize the trailer from industrial Galvanizers and they were very helpful. Do the trailer and all the bits for $1300. Works out to be $1.60 kg and not the $2.90 from another place. Did get a quote from NGI which was also good but their long bath is out of service until September, they were also very helpful.

    Yes mate, a number of blokes in our group have this same series, except with the smaller 5.0 litre MPI engines (Bravo drives), they all wish they had the 5.7L (300 hp?) for more grunt when fully loaded.
    Trouble is when you go for a test run, the outfit is usually light-ships and feels fine.

    Are you getting the fuel consumption figures via a SmartCraft digital readout? What sort of sea conditions were you running in at the time? Head seas and heavy trim tab use will cause fuel consumption to rise significantly.

    Depends on which drive (Alpha or Bravo), gearbox ratio, prop pitch and cruising revs you are running with, the Cruisemaster seems to sit up nicely around 22 knots (calm conditions) and use around 35-38 LPH.

    If you haven't already, consider fitting a Stingray (original) hydrofoil to the leg, as this alleviates the "lean" once up on the plane. They are also a boat which are trim tab sensitive because of the sharp, deep V, just takes a little getting used to.

    Remember to quickly raise the trim tabs fully, and lift the leg slightly when changing direction, running with the sea behind you to avoid "bow steering". This of course applies to any boat.

    Enjoy your boat Brett, you've got yourself a good, versatile and safe outfit.

    I am running twin Mercruisers 5.7l Mag Horizons (300hp) and return around 70-75lph (both engines) at 16.5knts so your figure of 42lph @ 20knts might not be far off the mark. What RPM do you have at this speed?

    I found this site was handy comparing RPM with fuel use on the Mercruisers

    Re: Boat Trailer project

    I bought a heap of gear from Huntsman also, very competitive. But they mucked me around with the shipping.
    I got a "your item has been dispatched" notification next day, 2 weeks later I rang to see where it was and they were "still waiting for the guards to be made" and would dispatch the order then.
    Not happy as i only got the guards to top up the order.

    I am sitting on 3600 rpm. If I take it to full noise she sucks 120 LPH.

    The 42lph @ 3600 RPM sounds about right but I thought your speed would be more than 20knts. Might need to look at how things are set up. What are you using to measure the fuel flow?

    The 120lph at WOT seems very excessive.

    I am running a flow sensor on my HDS. Totally agree with your statement. I should be moving a little quicker than the 20knts. I am going to start playing with props etc once I get the engine sorted out. Once I get down to 3200 rpm the boat falls off the plane also.

    Re: Boat Trailer project

    I say dont galvinise. when you get stone chips etc it gets underneath. And you have to drill holes through all your cross members and retap all your roller fittings and it costs a lot.
    I have made and galvinised a couple of trailers. Next time I am just 2pack tar epoxy painting.
    or there is another paint called light industrial coating (LIC)
    and filling with oil.
    My 22ft boat trailer I had to do this anyway over the galvinising after it started to deteriorate.

    I used to have a gal axle till I bent it and I replaced with black steel but wrapped in denso tape.

    Just in the process of looking for a winch and wonder what people think about this one on fleabay.
