Hi Phil, makes a lot of sense having an extended double tow bar on your trailer, bet it's saved you wet feet a few times! Also probably makes it easier to tow/reverse as shorter trailers are harder to reverse steer in my experience!

If you fast forward to near the end you will see how far into the water she goes and how much she floats. The rear bumper of the car is about 2ft from the waters edge...

* This picture shows you the weight of the boat on the roller and the bend in the hull as the result...
All these issues i am still in the throws of amending. If you building a trailer from scratch you can eliminate these through better design. One more important thing to take into account is, make the nose of the trailer longer than you think you need. Although on rollers, you will have to back it into the water a long way to get it to float....
Kind Regards

* Be careful with the design of your trailer, as when going over bumps the trailer will bend / flex and as it does the rear of the trailer will rise closing the gap between the trailer and hull. Its important to give a lot of support to the rear of the boat. As mentioned already, the axle position is very important.
Hope this helps
Phil

* The last keel roller taking the weight is too far forward due to the shape of the boat.

* Hello George, i too have a Navigator 18, with only a 50hp four stroke, and have had / noticed issues with my boat trailer. Firstly, the shape of the hull, actually the keel, on the Navigator stops about 2/3 ft short of the transom. This causes issues with the engine weight pushing the boat onto the rollers. One very good product to help with this is the 'transom saver' they are very good "if used correctly" (see pic).
Your trailer will need lots of support at the rear end and the multi or block roller combi's will help a great deal. Please see the pics for a better idea of the issues i encountered

Hi George,

I can not remember the exact weight of the Navigator, however, it will be about 950 kgs, on the amount of ballast it was between 50 and 75 kgs in weight..

Regards

Simon

Thanks Simon
I appreciate your help on this. Do you know what approximate weight would be in a navigator? And with regards to the ballast, how much would you advise and would I put this in the space just aft of the anchor locker under the seats?

Hi George,

Because you have a larger engine and the weight is higher than normal for a navigator trailer, I personal would go for the trailer set up for the Pilot as longer as the rollers and stands can be changed to fit the Navigator underwater profile and support the hull in the correct position especially aft where the support is needed to support the aft end of the boat on the road, if your Navigator does not have the ballast in the front of the boat I would put it in as a matter of course as it will help the sea keeping of the boat in rough weather or in a choppy seaway.

Regards
Simon

Hi Simon.
Thanks for that. It is a bit on the big side but I'll be gentle with it. My two trailer choices at the moment are a snipe trailer setup for a hardy 20ft (advertised here) and an SBS bunk trailer for an 18/19ft boat rated at 1600kg that's a bit more local. Do you think these would do the job?
Thanks
George

Hi George,

Welcome to the Hardy owners Club. I am a former employee of Hardy Marine from the time your navigator was likely to have been build. You say you have a Mariner 90 on the boat. As I remember we did not put such a large engine as that on the Navigator as we put a 75hp engine on the Navigator and that was powerful enough. When a large engine was fitted to the Navigator we did put about a 50 to 75 kg of ballast in the bow ahead of the cross bulkhead in the bow to keep the bow down and get the navigator on to the plane easier. As for a trailer any good trailer will do as long as the axle is well back on the trailer to counter the weight to the Mariner 90 on the back of the Navigator.

Yours Sincerely

Hi guys. Hope everyone has had a good Christmas and New year. I'm new to the club and am looking for a little advise with my first hardy. It's a navigator 18 with a mariner 90 on the back and I'm looking to see if anyone has any idea what this might weigh as I'm needing to get a new trailer for it. The interior is very basic so not much weight there.
Many thanks.
