Wave Piercing Bows

I am revamping orig design (class is defunct) to accommodate modern gear etc, and will build to operate as intended, in case.

That odd beach surf, even on Lake Michigan, can drive bow into sand too fast to bear off to avoid it...so we have to work with what might happen and why the foam idea is a softy, at least to me.

Of course... I agree with you, but we weren't talking about beach cats here. We were talking about these bows on 45-50ft, (15 meter) ocean crossing, performance catamarans.

I had a feeling everyone was picturing different boats when they were replying. I guess you were picturing beach cats when formulating your replies, while I was picturing what I showed in the pictures and videos.

That's why we didn't agree. I suspect that has a lot to do with why there were so many different views.

Everyone was picturing a different boat.

Yes, again I agree, why I added the note some days back about use etc. Race/cruise and so on, vastly different.

No problem. I think those interested get or got the picture. We don't disagree, just have varied views. Beach cats, AC boats, C Cats, Cruisers...and beer haulers like me.

My invention for race cruise reverse bow cruisers is retractable/housing stanchions and pulpits. Carbon of course....Now those with the money can enjoy the best of both worlds, safety on deck at anchor and less drag when pushing the spray envelope. Hardcore racers will want the lighter manual versions, others can be powered by our compressed air system. (lighter than hydraulics and electrics)
Furling bow nets are of course another of the go fast, look slick and party safe features nobody with fashion sense will want to be without......Our dyneema lifelines and custom netting are available in different colours to complement your paint schemes..... these nonpatented inventions are free to use because money should never come between a boater and his vices or devices......Actual production versions made by my yet unbuilt factory will cost lots of investment money deposited into a offshore account....you will have to wait for delivery while I clear the horizon....

Corley, amazing stuff, that big bird of a tri. Tough to get my head around it. Looks more involved than designing and constructing a commercial aircraft...


I fail to see why no one has designed a simple, changeable bow boat...should be easy if the bow stem is designed to handle. A set of slides, moveable plate to which the bow material is attached...seems easy.

Great idea A yearly fashion update, add-ons for the sterns too or offer the option as spares... for when the bow gets bruised or scratched... & a reconditioning service..... fender bows.. for touch parking & wharf pickups...... payment plans.... buy one now.. the other later... run out sales BOGOFree

Yep, why not?

Or, configure for the water, have a few wood bows around to add on as required...really, would work, if it did not alter one-design loa/lwl limits where required. Instead of deer heads along garage, bows. (I live in Minnesota, USA.)

We'll make the Fisher Snowplow add on bow for MN. Good idea, though.

I,m right there with you, even just sell bows for like famous sailors/designers to sign & wall hang em, pay extra for AC collector bow/s & more for classic collision bows, options for clear coated carbon etc etc.......

I had inflatable replaceable bows on another thread. I wonder what has the most sex appeal for the advertisers- the blow up or strap on......

A natural bow shape will evolve from the projection of the hull lines as catsketcher has mentioned. If you look at BPV's floats you get a good idea of a clean fair line developing the shape they actually remind me (vaguelly)of an evolved version of Lock Crowthers trimaran float bulb bows. You can do this with a few battens to try and develop the block to fit into the shape thats natural, fair and looks good. Looking at Mojo's bow front view in multihull world I agree that the hull looks a bit "forced" into shape.

Your right on the Mojo bow looking a bit forced, but overall it looks kinda groovy with the styling relief aft. So far as "optional" bow shapes I think the market would be quite "thin" but a bit of fun to discuss. Regards from Jeff.
