As a new boater, I might suggest a few things.
Where do you plan to keep your boat? Your location states China.
If you haven’t boated before look at trawler training schools. That experience would go a long way towards helping you feel more comfortable. Then, I would suggest a charter, such as the Amy Ann, a 38e charter in the PNW.
Based upon what you have stated in your OP, it appears that a Helmsman would fit your plans the best. The support during a build, and after sales has been extremely good for us, along with several other owners who I have gotten to know. That goes a long way towards customer satisfaction.
We own a Helmsman 38e, but I have also spent time on three 43e’s. As you step up a size level, the storage space grows markedly, much more than you would expect. I have not been on Chanprr’s 46 yet, but imagine that it steps up the same way with space. The pictures bear that out. If you plan to live aboard, space does matter.
Another consideration is single handing. If you plan to do that very much, then consideration needs to be given to what size you would be comfortable with. The access through the PH doors works really well for this, for tying off for locks and for docking.
We also like using the flybridge for travel when the weather is nice. That is a feature that really “opens” the boat up. The windows are another great feature, allowing for a really good field of view when piloting at the lower helm station.
The final point is that the Helmsman team does a great job working on custom changes to make the boat your own. That is one of their best attributes, along with their first class technical training and service,
We have been really happy with our 38e, and if we choose to move up in a couple more years, we will be looking hard at both the 43e and the 46.
Hope that helps!
