Major hull modification?

Well in about 12 months we will be taking our yacht out of the water to do a complete bottom job. We will be going to the fiberglass, new awlgrip, new paint, new bottom paint. I have a fiberglass repair on the bow to do, do to our boat humping the dock when we lost steering. Its a 3' gouge, so its going to require some big work. So my question is this.
Should I use this opportunity to do a modification?
I notice most new boats have a blunt, sharp bow. It goes from the top to the bottom almost vertical, before sweeping back underwater. I believe it may have something to do with the ride quality. So this got me thinking, what if i added a bow with the same shape?

this is us now. What if i add a long thin (4-6") section, then sweep it back once 1-2' underwater? Would this make the ride better? I know this would give me 3' of water line length, and that would help with top speed. Has anyone done this to an existing boat?
I am thinking this may make the bow wave piercing.

Re: Major hull modification?

IMO it would make your boat look weird.. to virtually no gain in performance that you'd notice...

Besides, one of the most common complaints from owners of newer boats with plumb bows is the difficulty in retrieving an anchor, esp in wind or chop, without digging a chunk out of the stem. Your present sloped overhang makes that pretty easy..

Re: Major hull modification?

I was thinking of having a side drop, like they have on mega yachts, for the anchor. Would work great with a large danforth.

Re: Major hull modification?

I would think you would need to change the shape for a long way back from the bow to make the transition. More vertical bows produced recently may have more to do with rating rules and interior space than sailing performance.

Nah..... Don't do it, IMO the bow looks fine. A saw cuts better at an angle vs laying it flat. So a slanted bow slices water better than a plumb bow, your boat wasn't designed for it.

I think he said he tried to use the angled bow to saw through the wooden dock but the dock won. I think a flat saw has a better chance of sawing water then a angled bow does sawing wood.

REALLY, REALLY bad idea.

Re: Major hull modification?

So much wrong with this idea... Figure you would have to rebuild at least the front third of the boat to get the shape right. It would be cheaper, and much easier to sell what you have and buy what you want.

Re: Major hull modification?

Not sure what they were thinking on some sailboat designs. This era of design was probably inspired by swept wings thinking boat will go supersonic. Oh they only forgot to put very long spike like they did on early efforts. It is your boat and if you can fix it to make it better go for it. Who knows teachers might finally learn something from gifted student who tried to improve.

If you think a 3" gouge is a big job then what you are proposing must be considered a gargantuan task. To do something like this so it does not look like a patch job would likely take a highly experienced FRP tech a couple of months with no weekends off.

The hysterical laughter you hear as you drive a way in your"new" boat ..... is the seller.
