Apex, I merely suggested and they took my suggestions. I do not take credit. We dealers needed boats that would sell and easily trailered or useful to make sailing easier.. Called in a sense marketing.
Jackdaw and RGranger, thank you for supplying those photos.
Bamabaxter;
1. Remember the boat weighs 5000 with the keel on a keel tray to support the weight of the boat.
2. It appears that the dual axles can be slid on the frame which is good to distribute the weight equally.
3. Most states do not allow over a 6 ft. overhang from the back of the trailer.
4. Bunk board supports 3 minimum but four fantastic. You could go with three screw jacks.
5. Keel guide good but not to low or the wings will rest on top. Seen that with bent wings. Lead bendable but not much.
6. Figure the weight of the boat, gear and trailer with a 10% margin for safety in gross vehicle weight for safety
to prevent swaying even with a dual axle.
7. Make sure keel tray are resting on cross braces with a minimum of 2 inch clearance when loaded. Never bolt to
or weld to an axle to include fixed, drop axle or torsion bars.
8. Brakes required but you will have to check with your state if required on both axles. If transporting thru other states,
your trailer will be recognized as long as you are pulling with your vehicle. Strongly suggest brakes on both axles.
9. trailer extension if planning to trailer launch.
10. This boat has the mast raise system but you will need to measure the back end of the boat to make sure you are not
over 13 ft. 6 inches on the back end as the mast is tilted up. You can lower that if you simply take a treated 4 X 4
section putting it over the bow pulpit drawing marks where it sits on the pulpit and remove an inch. That way the
mast step end of the mast is raised up lowering the back end. You will have to check.
11. Make sure the tires/hubs are rated total weight carrying a minimum of 7000 lbs. and if not you will have to buy new
larger hubs and tires but check the clearance of the fenders.
12. On that trailer the winch stand with bow roller is too short. Replace with a
taller one
One thing you need to also remember. the center of gravity is much higher and when modifying a trailer and towing, much different from towing a 240 which had a lower center of gravity. Suggest that you do not speed and take your time getting there.
The photo supplied by Jackdaw was probably made by Magic Tilt. Road King had made some for me but my friend, Ron Frisosky, who designed the sailboat trailers for Road King helped me to design one at the factory with me there but Road King no longer has the design. Magic Tilt copied it. Ron is deceased.
I hope the above helps you. Feel free to call if you want any other help. You have my phone number
