The bar is up out of the water here in all but the crazy stuff you probably wouldn't be sailing in SOLO anyway...and even then it's good to go...my boat storage buiidings in the background.
the bar rides high and dry here on the 18 too, only contacting water that breaks over the crossbar anyway
I bungee the bar to the dolphin striker on the 16 which keeps it out of the water for hull flying on the 16
side view of bar nesting under the front casting on the 16...nothing sticking out to catch lines on or hurt crew.
the padded bar rests across the hulls and nests under the wing struts on the 18
the boxes on the ends of the bar are just chunks of treated 2x4 assembled with squares of outdoor plywood
I had to add small shim pieces to make the 2x4 blocks match up with the tube OD
the bolt heads, nuts and washers need to be countersunk into the wood to keep them from ever scratching the boat
seal the bar ends inboard of the bolt holes, so the tube itself adds to the bouyancy of the unit. 1/4 inch bolts are strong enough and lightweight.
I thought about riveting eyes on the bar to attach the line, but they might scratch my anodizing..so I settled on this big half hitch...glad I did. It's soft, and also allows me to quickly remove the line and use it for other purposes, like towing another boat or sailboard in trouble
The tang on the end of the bar should be one inch or less, that's enough to keep it in place on the 18 and you want it to just hit the BOTTOM of the deck lip roll on the other boats
The rear loop attachs here on all the boats. Used large diameter woven POLY line that floats, is high vis, easy on your hands, and has a good load capacity
The front loop works well here on the 18, but must be like 3 or more feet forward to center the pull on the mast for righting a 16
I found that a simple knot lets me adjust the Stainless Steel trigger snaps easily as they slide along the line
I roughed up the truck bed liner material that comes in a spray can for really great traction on the bar, the round tube is cheap, strong and safer than standard square tubing.
