A Photo & Discussion Forum for Wharram Design Enthusiasts
I want to be sure we are talking about the same things here. I see the Tangaroa has a beam that goes from one bow to the other. I will call that beam the first beam. Then I see netting that is stretched from that beam aft to the next beam and I will call that the second beam. I am not the boat designer and you should probably contact Wharrams at firstname.lastname@example.org to ask Hanneke and James about this, but it seems to me that hanging your anchors over that second beam would be a good enough plan. The advantage of bringing weight aft and keeping the crew safer would a good idea. This is approximately where our Tiki 46 has her anchors hanging from the bow sprit just forward of our "second beam" which is located at station #3 in the Tiki 46 plans (our first "beam" is a wire). You may need a bridle to keep the chain and rode off the hulls, but we have never needed one on Peace IV because we use such a long snubber which is a heavy nylon line attached to the chain at one end with a camel hitch and to the "second beam" at the other end with a round turn and bosun's knot. We live on anchor so we replace our snubber annually. It takes all the pull of the anchor rode right onto the "second beam" so there is no chafe and no chain noise at night during storms. Where our snubber goes around the "second beam" we have it encased in a length of old fire hose. This idea came to us from Ken Hook, bless him.
While we are on the subject, we use a 66 pound French spade anchor and 200 feet of 5/16 hi test chain with 300 feet of heavy nylon rode to back it in case of extreme storm or depth of water. We use a wonderful electric windlass made by Ideal here in Rhode Island.
All the best, Ann and Nev
I used to have a Tangaroa and my anchoring arrangement was as you are proposing. I also had a bridle from the bows which I used mostly to attach to a mooring, but also used this to attach to the anchor rode depending on the anchorage. I found both ways fine, although anchoring from the bridle appeared more "stable", meaning not as sensitive to slight wind changes etc.
Something else worth considering is attaching a bridle to your second beam? Have not tried it myself but should not see reason why this should cause too much of a problem? This will prevent either hull from turning and touching the chain/rope. Cheers ~Carl
