The factory installed bow chocks seem to chafe line that runs through them. I’ve also heard a few chafe stories from my dealer. I do have some chafe guards, but what the heck good are the chocks if they just chew through line? I don’t typically use the chocks, but am thinking of using them with the chafe guards when picking up a short term mooring.
 
Has anyone replaced their bow chocks with larger ones? Looking to do the same...

Thanks,
Bobby
 
In our 2009 R-25 Classic the factory installed bow chocks were never Intended to be used for mooring lines. The chocks angles (looking from above) were pointed to the aft of the boat. Running a mooring line through those chocks then angling the line forward to a mooring buoy will definitely result in chafing. I installed additional chocks at the bow with the chock angled straight forward.

I believe there was a post on these chocks some time ago.
Depending upon your dock line arrangement (angle of the dock lines) you might benefit from switching your chocks left-right.

That would improve the angle and reduce the chafing.
 
Consider applying Maxi-Jacket to a section of your bow lines.

I did it after it was recommended in a 2015 Practical Sailor article.

I measured and marked the sections of the lines that pass through the chocks and added a foot on either side. Brush the coating on over a piece of cardboard, work it in with gloved hands and hang the line up to dry overnight. The results have been impressive, and there has been no significant chafe since I applied the coating.

I formerly used rubber chafe guards, but this makes it much easier to get the line into and out of the chocks.
 
Hey Barry,

I should have contacted you directly. It was your boat I saw them on a few weeks ago that got me thinking. BTW, we are in Cuttyhunk right now. Are you cruising these grounds still?

Best,
Bobby
 
I too added additional correctly facing chocks. Factory-installed are set up for chafing lines, We should check if Fluid Motion owns stock in a rope company :lol:

Barry, I like your fabrication of the bow chocks. Are they thru bolted? and how did you do it?
 
It shows up over and again. Fluid optimizes cleats for a side-tie to the floating docks of the PNW. They are not well located for fixed piers more common on the East Coast.

Since you are located on the East Coast, its a worthwhile project to think through locations to add cleats that fit the area, and do them all, at one time. By that I am including the addition of chocks more forward-facing than the ones generally installed, that would be more useful for both an anchor bridle as well as bow lines in fixed piers. Remember, they have to be bedded and through-bolted. Which means that the locations have to be somewhere that you can install nuts from below deck.

Second, chafe is a fact of life in boating. You can't get away from that, and do need to consider strategies to minimize it. Docklines and anchor lines are just the beginning. Boats move. Even past the movements from waves, you have constant vibration when underway. Wiring and hoses can wear and chafe from vibration alone. Vibration can and does cause nuts to back off and loosen in wiring and elsewhere, and in some cases the nuts have been known to come completely off. I've heard of cases where bottled water vibrates against something and wear through the thin walls of that plastic, so if that can happen just think about something more important like wire runs. This is just one more reason why the advice is given often to make a top to bottom inspection of everything on a regular basis, at least annually. Build checklists to be systematic about it. Clean electrical connections and snug them up. Snug up hose clamps. Check for chafe. Use a meter to check power delivered to electronics. The stories are legion about weak battery output that causes people to suspect weak batteries, but it turns out to be no more than a need to remove and clean the battery posts and connections.
 
Hi Bobby. We are in Hyannis until Friday morning then back to Onset for a week before heading back north.

We installed larger, better-located chocks also purchased through Winter Island Yacht Yard. On our R29 Classic, the chocks were too far aft for mooring and were far too small to accommodate appropriate sized line dock or mooring lines. There are pictures in my album.

Thanks, all. Plenty of boating experience on my part, and I’ve had plenty of boats. My marina, as well as the majority I visit have floating docks. I don’t use the chocks. I just can’t figure out exactly what the factory chocks are good for. I was hoping they’d help with our short term mooring. I probably won’t use them, but if I do, I’ll use my chafe guards. Maybe ai’ll install some smooth chocks like we had on sailboats or reverse these.
 
Alice J, the chocks are thru-bolted and installed by my dealer.
