Need Help with Venture 23 Boat Lift Bunk Specs/Hull Deadrise

SEdowneast

Hello Everyone, well I guess I will be part of the group in earnest soon, as we’ve just ordered a new Venture 23. Very excited about the adventures ahead!!

I will need to get my boat lift bunks built for the new boat and am looking for the specs for them. If anyone with a Venture 23 could help, it would really be appreciated.

I am specifically looking for the deadrise angles for the hull at the stern and the angle of the hull directly below the front of the midship cleat. The “level” tab of the “Measure” app on an iphone can be used to take angle measurements.

I am also looking for the centerline distance between the bunks if someone has those….or, even the same measurement of the back bunks of a trailer that has been set up specifically for a Venture 23.

Look forward to being active with the group in the future!

Thanks so much!!

Have you tried contacting NMI (Northwest Marine Industries) that is building your boat? I am sure they have all these technical specs since they set up the trailers for these boats as well.

I have asked the questions via the dealer but haven’t gotten a response yet. I think they are quite busy these days! Thinking someone on here might have already been down this road, this my post. Thanks!

Interesting questions: are you going to change the angle of the boat surface (upper surface), by the angle of the deadrise of the various stations in the hull. I am not sure I have ever seen that done. Certainly now many of the lifts are fitted for the deadrise aft--this is especially important in high dead rise boats, such as Contender (up to 26* at the transom.

I have a 25 year old lift, which I have put boats from flat botton, minimal dead rise, a 27' boat with 18* deadrise, a several 20 foot boats with 18 to 20 degree deadrise at the transom, and two different catamarans on--all the same: two 2X10 true dimensional salt water treaded timbers on each side. They have remained the disance apart most of the time--and that was for 8' beam catamarans. I would have had to build (custom wood work, which I would do my self with a power planer) for each boat doing that. No ill effects on any of those boats from the way the bunks were set.
