Before I dive into Gords wonderful bounty of info I did want to say that I have been doing a bit of research
of my own. Well, actually I have been dock
walking and looking at bowsprits (boats make even boring research
). Anyways, I am amazed at how many bent, warped, or just plain broken bow rollers their are. The common denominator is that they were all production rollers (minus one). I have looked at a couple hundred bows today and none of the windlines or lewmars were bent. Tomorrow I had planned to take pictures of the custom bow rollers that could work for my boat. Saw a couple bent dive n dog, at least, I am pretty sure they were dive n dogs
. I also saw one warped or twisted seadog bowroller.
I wrote windline to see if they had any insight to which roller would work for my rocna
15 (or soon to be rocna
15, I am hoping I will get one for my B-day
). They wrote back to say they did not know. Rocna's website said that a fluke style roller works best.
Hope that helps,
PS -off topic but interesting (at least to me) out of all the production modern sailboat bowroller/anchoring platforms I saw today the Hunters had everyone beat, man alive those things are beefy! I bet you could pick the whole boat up with em, good job Hunter
