Default Deadrise in a WA

I've been comparing boats with small cabins in the 25-30 foot range. Fishing is secondary to cruising for our purposes - lots of anchoring on the beach, some 1-2 hour trecks to the US Virgin Islands from PR. Everything is a trade-of, overall I'd want as much deadrise as possible to navigate rougher seas but is it so that lower deadrise will make the boat more stable when still? Will we sleep better in small cabin, in say a 26 footer on a bay, with a 20 deegree deadrise or one with 23? Does added weight of a WA compared to a CC make deadrise any different of a factor?

Get a grady white with the Seav2 hull.

Like you said, everything is a compromise. In PR you need deep v and weight. It’s rough there. More weight = stability = more fuel consumption. 20 and 23 deadrise are both deep v. 20 will be more stable on the hook and drift. 23 will be smoother when at high speed. At cruising speed on those seas on your way to Culebra or VI, the entry and midship deadrise are more important than the angle at the stern. Don’t get stuck on the numbers, and just sea trial any boat that meets your layout needs.

Thanks for the replies! Makes sense micura, agree with what you're saying.

Re: Grady's - I know they're great boats, maybe the best for what I need. I'm looking at used boats, years 2003-2010 most likely. There's the Islander, the Journey, Sailfish?, and the 26 Express from what I've seen. Don't love that they all seem to have black bottom paint and not the most stylish in my opinion. But I would want to check any rotting in wood, since I believe all Grady's have wood, unlike the others l'm considering - Robalo, Hydra-Sports, Century.

BW and GW are obviously at the top of my list but a big pricier and not crazy about the look of either of those brands, for those years. Also, I may be wrong, but I see them as more hardcore fishing boats, with the fishing looking chairs and fishing space, when I prefer more seating room and seats that recline or convert into longer charms for lounging.

get big deadrise for nice ride in seas but big chimes to reduce roll at rest.

Sailfish are variable deadrise similar to seacraft, they work very well
inshore and “offshore”
they are setup nicely and people seem to like them.
fit and finish is not top tier, but good value.
only non custom boat that has a 27’ wa pilothouse option!

Is this going to be your first boat? Where are you using it?

The difference in deadrise will only make a difference to stability (and ride for that matter) if EVERYTHING else is equal - there are much bigger factors than deadrise to affect stability - the relationship of COG to COB will be a greater consideration and no spec sheets will tell you that. Ultimately the only way to know if it’s acceptable is to try it for yourself.

Second. I have a 2001 Hydra-Sports 20 LTS, the smallest of the vectors. For a beginner boat it's been great, I don't hesitate to take it out below 5 foot waves, though usually don't go too far. But having one engine and a small size aren't ideal to go to the US Virgin Islands, which I'd like to go to a bit more. I use it in northeastern Puerto Rico mostly, Fajardo, and have made several trips to Culebra and Vieques with no problems, those are nearby islands about halfway to the USVI (Culebra is about 26 miles from Fajardo). Looking to step up to 1) longer boat with twin engines, 2) a cabin because my gf wants one with a bathroom, kitchenette, and place to sleep. Unlike me she grew up in boats and understands a small cabins are not the most comfortable. I don't plan on sleeping on it much, will stay in hotels when I can, but would like the option. Otherwise a center console with a bathroom would be my other option, but I can see us using the kitchen and v-berth more than most.

I'm not very familiar with the conditions in Puerto Rico, I imagine many here are not. Your GF is right in that small cabin boats are not pleasant to stay in, they mostly turn into places that people store their junk. If you are determined to have a cabin I would want to maximize space inside, an express instead of a WA. The weather in PR seems quite warm, to the point it would likely be uncomfortable to sleep in a cabin without air conditioning? Then you would also want to look into something you can fit a generator onto as well.
As far as the trade offs between ride and lateral stability on the drift, this is your second boat and you've been in the seas there long enough to know what's usually bothering you more when you're running your boat. Do you have mostly situations in which you feel like you're struggling just getting where you're trying to go without being pounded? Or are there more situations in which you're drifting or stopped and the boat is rolling too much side to side? Weight of a WA or express doesn't help with the ride, if anything they usually run a bit worse than the equivalent CC version of that hull because the helm is further forward and the boat is more top heavy. Going bigger will help too with both. You could also look into a catamaran. Then you'll have both quite a lot of lateral stability as well as an excellent ride in head seas. I'd get a ride on one if you can.
