Mast and Rigging Weights
Hello Jorgen.
The following may be of use:
The following weights, just measured, may be of interest for comparison purposes.
1. My carbon fibre mast with 3,5mm Oregon Pine veneer, mast head light and wiring, all fittings including all the blocks and shackles weighed;
= 10.90Kg
2. The standing rigging (wire rigging) weighed:
= 2.4kg
3. The running rigging (all halyards, topping lift, and shackles) weighed:
= 3.2kg (dry)
4. The Honnor Marine solid wooden mast with fittings (rigging band and tangs) weighed:
= 36.30kg
The carbon fibre mast with just rigging band and tangs, pivot bolt tube (as 4 above) weighed (from memory):
= 9.50kg
From the weights given above you can see there is a tremendous difference between the solid HM mast and a carbon fibre mast. So far, I have always managed to put the carbon fibre mast up un-aided. Taking it down is even easier. With the old solid wooden mast it often took three to get it up onto the boat and raised. Now I can carry it about easily.
Obviously the with the rigging the weight increases especially if the ropes get wet but for me is just manageable. I am considering making a tension device that makes that critical point (about 45 degrees-when you have to move forward on the coach roof) just that bit easier. It would be attached to the trailer but can be modified to use on the just the boat for “bridge Lowering”.
The reason for making a carbon mast was to off-set the extra towing weight of my inboard diesel but it also makes the boat now much stiffer! It’s a shame that HM didn’t continue to make the hollow “Bird Mouth” South African original design instead of just copying the Shrimper. Simon Head had one made in the UK in Bristol.
Hope the above helps.
