We sail to Portsmouth UK and check out the Selden Mast factory. They build sailboat masts, including the latest in high-tech carbon fibre. #seldenmasts

This “expert” guy hasn’t heard of the roll moment of inertia. Lighter masts do not improve comfort as he claims, instead they allow larger accelerations of hull and therefore more discomfort. Basic physics

The comport he is talking about is reduced heel.

If designed into the boat, a CF rig would be very comfortable. It would require less ballast to bring the roll moment into comfortable levels. On a boat like my seasprite 23 with over half it's displacement in lead, a lightweight rig would make the boat very "snappy" as it returned to level after rolling over a wave. A boat like my GP14 Dinghy, being an unballasted open boat, it would make her less likely to capsize.

Imagine a carbon mast on a trailer-sailer like the Catalina 22 or 25... could make raising/lowering the mast that much easier, as well as increase performance for the reasons stated.

Just out of curiosity, how much would a mast and boom for an,average 28ft sloop cost I wonder?
@mazdarx78873 жыл бұрын
I like the idea of carbon fiber but if the is damage, the mast is toast. At least wth aluminium, it can uaually be easily repaired

Great update! I've just been looking into carbon fiber masts for our boat.

Hi is it necessary to fully stay a carbon fibre mast?? Or can it be the case that it is only 'braced' in position by the foot of the mast and where it goes through the deck ?
@DistantShoresTV Жыл бұрын
Carbon masts can be designed as needed, either as a stayed mast with shrouds or unstayed.

I wonder what is the ratio of resin to fiber in the cured mast.
@mckenziekeith74342 жыл бұрын
Probably around 60 percent fiber and 40 percent resin by weight. That is the figure I have seen on other channels such as Easy Composites Ltd channel. Hand layup with excellent technique is maybe around 50/50.

paul, thanks for the educational video. one question, are all the carbon spars cylindrical? I see your new pole would be but what about masts and booms? non cylindrical mandrels? thanks and smooth sailing to you.
@DistantShoresTV8 жыл бұрын
I have seen some lovely carbon masts, built I believe with mandrels in the mast shape... but I am not sure about the method. Perhaps I can get Selden to chime in and answer your question.
@rolandbloemers99098 жыл бұрын
+jfelix I wondered that. I suppose a cylindrical mast is fine for a racing yacht but sailing yachts need all kinds of equipment bolted to them and a cylinder isnt ideal. There clearly must be a way to do it, after all many carbon fibre constructions are obviously not cylindrical
@DistantShoresTV8 жыл бұрын
+jfelix Yes Selden can also make regular mast extrusion shaped ones as well. They are still wound on like in our video, but the mandrel is mast shaped... then they bond on spreader bases etc...
@jfelix76508 жыл бұрын
+Distant Shores TV Paul, yes that does make sense as fiberglass and carbon fiber can be molded to almost any shape. Why not a mandrel of an oblong shape? Thanks for the follow up. Now get back to sailing and making excellent videos!

I have trouble imagining that the weight difference, about 40%, would make any difference at all. I could see it for extreme racing purposes, but for cruising, you're going to want aluminum.
@neil23857 жыл бұрын
It makes a tremendous difference. RIghting moment, weight aloft reduced. this and a few other huge factors which equal much better boat performance. Not just in speed but in handling and thus the helmsperson and crew tasks of sailing the boat are facilitated

huge in head and pocket. inertia reduce roll freq seasickness and capsize chanse but snobs love to belive vice
