Does anyone know the proper measurements for a Hobie 18 trailer?
I purchase a used HC-18 with galvanized trailer last fall. The trailer is outfitted for a catamaran but the hulls feel too close to the tow vehicle. When I need to make a tight turn (at the boat ramp, etc) the forward tips of the hulls get very close to my van. I’d like to know if my trailer (tongue) is too short or if I’m too cautious

.
I have the boat positioned over the axle to give sufficient tongue weight. The forward hull supports on the trailer are positioned just forward of front cross-bar, and the rear hull support is between the rear cross bar and the dagger board trunk. The rear hull support is as far back on the trailer as it can be.
The Tips of the bows are approximately 16 to 18 inches behind the tip of the trailer ball coupler. How far in front of the bow should the tongue of the trailer extend? Where is the best location for the hull supports? Is there a specification for a Hobie 18 trailer?
I can’t do much about the hull support but I think I can get a longer member for the tongue of the trailer.
