Hi Dear H14 sailors,

I am new to this forum. I am a boatbuilder, now making a 41ft sport carbon catamaran, my costumer has a broken hobie 14.

So I have to rebuild the broken hobie 14 too....

my customer has an idea to make a wavepiercing bow for her....like wildcat has...
he thinks that it will gives more volume at the front, and will be less pitch poles...and Develop the inside face to a rectangular transom with foam, glass .....since he is around 90kgs...

it could be funny, but I don't have any idea it will work or not.....

by tha way we rebuilt an old tornado into a wp bow and it works absolutely great on these small but straigth waves...

do you have any ideas about it?

I made some scatches

the other question is the mast....

I have to put a square top main on it and a code 0/genaker. ..will I have to put a pair os spreaders to the mast, or it is stiff enough?

I is worth to use a mast rotator?

Thank You your answers,

Lafouchat

Search for info on the F14's. None in the US that I know of, but a handful in Australia.

You are better off buying or building another boat.

Wave piercing bows are a combination of profile (the lower forward protrusion) and cross section (wider down low, narrow on the deck).

A Hobie 14's hull is completely opposite to this, and trying to make it "wave piercing" will only add weight (where you don't want it).

Trying to make the 14 something it isn't is a guaranteed fail.

Thanx,

The costumer doesnt want another small boat, he wants to fix it...
The idea comes from the decision 35 class, where it has kind of sideview as it has redrawn.
The weight wouldnt be so much, app 1,8kg per hulls with vakuumated prepreg carbon with foam.
We give a try I think.

I agree with Matt, trying to change the Hobie 14 would be a bad, bad, bad idea. You couldn't come close to achieving what you want just by altering the bows. You would be better off starting from scratch to get true wave piercing bows--check out the A cats for ideas.

However, I have installed a screacher (Hooter, Code Zero whatever) on a 14 and it was a blast. It was a handfull, but I made it happen. Pictures are here:

The square top main was great in big wind, but horrible in the light stuff

If I was going to play around with this, instead of the wave piercing bows (which probably won't work out too well), I'd do something along the idea of anti-pitch pole foil instead. I'd also look into installing a front tramp to prevent the gennaker from going in the drink.

Best of luck,

Dan, what do you call that gooseneck type assembly in the boom for the outhaul setup? I'm thinking of a new main, loose footed, and that'd be nice... along w/upgrading to a rotator. Not sure the downhaul is worth it?

Thx,
Rob.

I think the rotator is really only important when sailing uni. When I had the jib or hooter and didn't sail dead down wind, the mast roatated just fine on its own. The downhaul is really important and the 'new' style adjustable on the fly is really nice.

I used an outhaul from a Prindle 16 on the 14 boom to get the adjustment on the loose footed sail.
