While many see the 65' Mac is a poor cruiser, some see the advantage of the long narrow hull as a plus! Both models (Pilothouse vs Non~Pilothouse) offer an area back beyond the ladderwell which can easily serve as a 'Garage' of sorts as it has been referred to by it's owners. There is a large area for storage, spares and whatnot.
I have said many times that I can see a Mega~Mac in my future, just haven't convinced my other half on the whole idea of long~range cruising as yet!
The non~ Pilothouse version even has a bathtub, and something that was a plus for the 1st mate actually. Just how many boats do you see even in that length with a doggone bathtub? Of course I have heard that it makes about the best cooler for beer out there also!

Actually a shoal keel, Pilothouse with a bathtub would be the ultimate for me, but alas, these are not available, but I imagine I could outfit one with a tub!
The boat mentioned in the 1st post here is 'Barking Spider' I presume? Nice boat and outfitted/preserved well.
Two were looked at by us here in San Diego, both non~pilothouses. One had some mighty huge blisters, above the water~line believe it or not. And the other sustained damge by what was described as a soft grounding and the area around the head door was tweeked between the inner liner and the lower deck liner in such a way that only removing the whole deck, popping it back in, and re~installing, would have cured!
The way I see it, is... even though 10 people could supposedly be berthed in a Mega~Mac, to cruise, it could only be done comfortably with about 5 or so, and all stores/outfitting required for any serious passages.
BTW, they can and have been trailered across the USA. Yes, they are on a flatbed, but knew of one that went from San Diego to Forida on a Semi~ride, so it IS possible!
I have talked to many people who brought these boats through Panama, and all Good reports were offered. Besides the naysayers who haven't done long passages on these boats, only heard the Bad and Ugly from them. One joker said he HEARD one split down the middle like a zipper. And he said that was because they were molded together. I called him on such a accusation, as I went to the factory several times in the '80's and '90's when they were being produced, have the brochures and saw all phases of assembly with my own eyes.
People perpetuate negativity when they percieve only one type of boat is right for them. In my opinion, no one has yet to build a similar~ faster, and sensible craft such as this Mac~Monster! But again, that's just me I presume!
I still revere Roger Macgregor as the builder of the best boat built for the buck, bar none, owned three models so far for over two decades, and can't see myself in any other brand!
Ahhh, the 65'.....Some day perhaps.......
In the meantime I am actively seeking a crew position, and will gain knowlede and experience hopefully so I can make a wise decision, and hopefully cast off my landlubber lifestyle for the South Pacific and beyond!
