How does the 42DS have a longer LWL than a 45DS?

[jchan]

SailboatData.com has the specs listed as follows.

45DS
LOA: 45.11 ft
LWL: 37.57 ft

42DS
LOA: 42.42 ft
LWL: 38.06

This makes no sense to me. From just the eye test of looking at a 45DS, it doesn’t appear that there is nearly an 8 foot difference between the LWL and LOA. I want a 45DS, but it seems the 42DS should have nearly identical interior volume, aside from the difference in beam.

Has anyone been on both? Or can someone explain the stark difference in LOA to LWL ratios?

I agree this looks odd.

I know that 42DS is longer than the 43DS (both LOA & LWL) but I’m as baffled as you about the situation with the 45DS.

All I know is that I loved my 42DS and it sailed & motored very well. When we decided to go bigger we didn’t even consider the 45DS but jumped straight to 50DS.

Be interesting to see if anyone here knows the answer definitively!

"HOW MUCH NEWER" is the 42 vs the 45? Many of the new'ist boats have a vertical to the bow angling forward, giving a smaller boat more waterline. I want to say this feature is a "canard bow".
So reality is, a newer 42' boat, with an increase of width, bullet shape with the scow bow, said 42' may have more room than a mid 80's 50'! Along with being faster due to the DLW of 5-7' more.
Being as no years are being mentioned, it hard to say on the true why the DWL is longer. I do recall the mid 05 SO 35 having an inch or three long DWL than the SO 37. Locally the 35 was rated some 15-20 secs a mile faster due to a two year later design.

this is exactly the reason: a more vertical to the bow angle foreword.

the main difference between 42 and 45 is 10 cm in the aft cabin, exactly in the sofa of the AFT Master cabin.... and as a consequence 10 cm more in the cockpit and in the saloon ... nothing more, nothing less.
sincerely there is no difference between the two, a part from the fact that i found the 43 faster, but might be an impression.

In that case isn’t the 42 a smarter option than 45 as you might pay less for berthing and haulout fees (which are often per foot)?

Whilst it is true that length matters …. (Ahem!) ….. for a marginal speed increase, important for racers but probably less important for the average cruiser, there is the matter of increased beam that comes with increased length, my 35 may be a smidge longer at the water line than a 37, but it’s the extra few inches in beam that makes the 37 that little bit roomier, and comfort wise with more than two on board it is noticeable.

That's what I'm thinking. I was strongly considering the 45, but seeing that LWL and knowing it will be more expensive regardless has deterred me.

The 45 is actually newer, which is why I was surprised to see the stark contrast.

Yes it would bug me to own a boat that I knew was costing me more to own but was slower. Every time a marina / haulout facility / insurer / boat painter asked me “how long?”, I would feel a bit annoyed!
